The logic for looking up an array mapper seems to have a problem if you have multiple array mappers which act on the same key/attribute name (though in different classes).

I think this needs a class reference check also?

Hello!
Is there any way to track the progress? Because I have a few megabytes json file, so it's going to take time and I want do draw a progress bar.
Thanks.

Hi all,

I'm having problems to parse a JSON Structure like that:

    "_id": "556cedaf0cf2bfc0f5ba1820",
    "name": "Easter",
    "description": "Easter Moons"
  }
}

]

I have a Moon class defined in this way:

@interface Moon : NSManagedObject

@property (nonatomic, retain) NSNumber * moonId;
@property (nonatomic, retain) NSString * imageUrl;
@property (nonatomic, retain) PMCategory *category;
@property (nonatomic, retain) Coordinates *photoCoordinates;
@property (nonatomic, retain) Coordinates *textCoordinates;

@end

And a the corresponding DCParserConfiguration setup for this class is:

-(DCParserConfiguration*) getMoonsParserConfiguration{

DCParserConfiguration *config = [DCParserConfiguration configuration];

DCObjectMapping *mapId = [DCObjectMapping mapKeyPath:@"moonId" toAttribute:@"_id" onClass:[Moon class]];
DCObjectMapping *mapUrl = [DCObjectMapping mapKeyPath:@"imageUrl" toAttribute:@"imageUrl" onClass:[Moon class]];

DCObjectMapping *categoryToMoon = [DCObjectMapping mapKeyPath:@"category" toAttribute:@"category" onClass:[PMCategory class]];

DCArrayMapping *mapperPhotoCoordinates = [DCArrayMapping mapperForClassElements:[Coordinates class] forAttribute:@"photoCoordinates" onClass:[Moon class]];
DCArrayMapping *mapperTextCoordinates = [DCArrayMapping mapperForClassElements:[Coordinates class] forAttribute:@"textCoordinates" onClass:[Moon class]];
DCArrayMapping *mapper = [DCArrayMapping mapperForClassElements:[PMCategory class] forAttribute:@"category" onClass:[Moon class]];

[config addObjectMapping:mapId];
[config addObjectMapping:mapUrl];
[config addObjectMapping:categoryToMoon];
[config addArrayMapper:mapperPhotoCoordinates];
[config addArrayMapper:mapperTextCoordinates];
[config addArrayMapper:mapper];

return config;
}

I've added the following line to config trying to fix the problem, but I think that shouldn't be there.

 DCObjectMapping *mapUrl = [DCObjectMapping mapKeyPath:@"imageUrl" toAttribute:@"imageUrl" onClass:[Moon class]];

This line is confusing for me, I imagine on my first approach to this library that the mapKeyPath is the server response JSON key and the attribute is the Model attribute, but seems to be that they must go swapped?

 DCObjectMapping *mapId = [DCObjectMapping mapKeyPath:@"moonId" toAttribute:@"_id" onClass:[Moon class]];

Otherwise I have an error validating the key into the DCAttributeSetter class implementation, the line that validates the value fails with the first attribute If the line above is not present. Anyway I couldn't solve the problem at all, now with the second attribute imageUrl (named identically on the hash) is failing on the same line.

if([object validateValue:&value forKey:attributeName error:nil]){

I'm really stuck with this and any help to try to solve my issues is really appreciated.
Best,
Hernan

Hi there, after the latest modifications you merged from my pull requests, some features need a version bump to be correctly referenced by Cocoa Pods.
Could you create a tag 1.4, please ?

Hi,

I got some issues when converting NSDictionary / NSArray from JSONKit with DCKeyValueObjectMapping library because it does not support NSNull representation.

By default when a object is nil, JSONKit will use NSNull.

I fixed it in DCNSDateConverter, but there may be more cases.

1 - Data loader code (Loads Facebook repositories on GitHub)

Note: Some repositories don't have push date. In this case JSONKit sets NSNull in dictionary when deserializing the data.

AFHTTPClient *httpClient = [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"https://api.github.com"]];
NSURLRequest *urlRequest = [httpClient requestWithMethod:@"GET" path:@"/orgs/facebook/repos" parameters:nil];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:urlRequest];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSString *jsonString = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSArray *json = [jsonString objectFromJSONString];

    DCParserConfiguration *parserConfiguration = [DCParserConfiguration configuration];
    parserConfiguration.datePattern = @"yyyy-MM-dd'T'HH:mm:ss'Z'";
    DCKeyValueObjectMapping *parser = [DCKeyValueObjectMapping mapperForClass: GHRepository.class andConfiguration:parserConfiguration];
    NSLog(@"Data loaded");
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

[operation start];

2 - GHRepository code

#import "GHOwner.h"

@interface GHRepository : NSObject

@property (nonatomic, strong) NSNumber *identifier;

@property (nonatomic, strong) NSNumber *forks;
@property (nonatomic, strong) NSString *full_name;
@property (nonatomic, strong) NSString *language;
@property (nonatomic, strong) NSString *name;
@property (nonatomic, strong) NSNumber *open_issues;
@property (nonatomic, strong) NSString *url;
@property (nonatomic, strong) NSNumber *watchers;
@property (nonatomic, strong) NSDate *pushed_at;

@end

3 - Code to fix NSNull in DCNSDateConverter class

- (id)transformValue:(id)value forDynamicAttribute:(DCDynamicAttribute *)attribute {
    BOOL validDouble = [self validDouble:[NSString stringWithFormat:@"%@", value]];
    if(validDouble){
        return [NSDate dateWithTimeIntervalSince1970:[value doubleValue]];
    }else{
        NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
        formatter.dateFormat = self.pattern;
        /* Code to fix the issue here */
        if ([value isKindOfClass:NSNull.class]) {
            return nil;
        }
        return [formatter dateFromString:value];
    }
}

When parsing an empty array from a property it crashes, it asumes it can check objectAtIndex:0 but does not check if the list is not empty.

DCNSArrayConverter line:38

Is this possible?

Not worked on Swift

Hi dchohfi,
I really don't know how to deal with core data object mapping using DCCustomInitialize.
Could you please write a few sample codes for me? THX : )

can I use this with os x application? since podspec doesn't specify os x version requirement I can't install it using pod.

Like so:

+ (DCKeyValueObjectMapping *)mapper {
    static DCKeyValueObjectMapping *mapper;

    if (!mapper) {
        @synchronized([self class]) {
            if (!mapper) {
                DCParserConfiguration *config = [DCParserConfiguration configuration];

                [config addObjectMapping:[DCObjectMapping mapKeyPath:@"id"
                                                         toAttribute:@"repositoryId"
                                                             onClass:[self class]]];

                [config addObjectMapping:[DCObjectMapping mapKeyPath:@"description"
                                                         toAttribute:@"descriptionText"
                                                             onClass:[self class]]];

                mapper = [DCKeyValueObjectMapping mapperForClass:[self class] andConfiguration:config];
            }
        }
    }

    return mapper;
}

+ (Repository *)instanceFromDictionary:(NSDictionary *)aDictionary; {
    Repository *instance = [self.mapper parseDictionary:aDictionary];
    return instance;
}

Will my calls to instanceFromDictionary: be thread-safe?

I have a JSON like your Tweet example - that includes simple attributes and Array of complex type (includes several attributes too).
I'm able to parse it into the object pretty well - my parsed object contains NSArray with items of my custom type.
But when I'm trying to serialize this object back to the JSON string (through the NSDictionary) I have some troubles:
it creates NSDictionary that contains key with array of my custom type and i couldn't convert it into the NSString using NSJSONSerialization (got an exception 'Invalid type in JSON write (MyPhotoModel)')

Since @property without memory attributed use strong for memory storage, converter property in the class DCObjectMapping should be marked with weak attribute to avoid potential memory leak.

This

@interface DCObjectMapping : NSObject <DCMapping>
..
@property(nonatomic, readonly) id <DCValueConverter> converter;
..
@end

Should be changed in this

@interface DCObjectMapping : NSObject <DCMapping>
..
@property(nonatomic, readonly, weak) id <DCValueConverter> converter;
..
@end

Hi,

I've imported #import <DCKeyValueObjectMapping/DCKeyValueObjectMapping.h> as suggested but DCParserConfiguration, norDCArrayMapping` are visible.

Do you have some header in this pod that includes all other headers? Would you mind adding some header with the following imports (and other if necessary):

#import "DCKeyValueObjectMapping.h"
#import "DCParserConfiguration.h"
#import "DCArrayMapping.h"

As part of Apple's big refactor job in iOS 8 one of the things they've changed is to turn the -description method in the NSObject protocol into a read only property.

If we have some JSON that returns a field named "description" the library will throw an exception (full stack trace below). This is because it's trying to set the readonly description property on NSObject.

Now I don't think this is really an issue with the KeyValueObjectMapping code itself. Its just that now "description" should be treated as a restricted keyword like "id" and it should be handled by developers with a custom DCObjectMapping map key path.

That being said, it's probably important to make people aware of this. "description" is a far more likely JSON field name than "id" or "alloc" or any other reserved keyword. Maybe you could throw your own exception which could contain a more helpful description than Apple's.

I have model with enum property and server returns the string at same property.
When I try to parse it fails to convert the same string to enum property. Is there any possibility for this ?

Sometimes the json data type and the type in the model does not match. For example something you expect to be an array is a string. In these cases the parsing should have a error parameter, so that we can get a sensable error if that happens.

Please enable bit code for the project to effectively support App thinning in iOS9 and WatchOS

When model class has an NSURL property and there is an input string associated, which is url and which has a space in it, then it is not converted to a NSURL object, but been left as NSString and been assigned to an NSURL property.

Hello, I use KeyValueObjectMapping for getting data from database.
Everything works pretty well but it doesn't assign value to custom class fields containing the char "_" and this is very strange.
Can this problem be solved? Thanks.

Automatic KeyValue Object Mapping for Objective-C, parse JSON/plist/Dictionary automatically

Hello,

I'm new to KeyValueObjectMapping so my question might sound easy: how to create the two relationships of a one-to-many relationship?

For instance, let's take the example of the User that has many tweets:

• 1. There's a NSArray of tweets in the User model
• 2. There's a User property in the Tweet model

I figured out to do 1) very easily but can't find a way to do the 2) link. Is there any way to do that?

Cheers,
Martin

Hello,

since you are using [NSDate dateWithTimeIntervalSince1970:(NSTimeInterval)] in the DateConverter class, you need to pass this interval in SECONDS, not millis.
Do you prefer to stay with seconds (and change the documentation where you say milliseconds) or /1000 the value? I can send a pull request for the second one.

Any idea about this?

/Users/wu/Library/Developer/Xcode/DerivedData/KeyValueObjectMapping-biwhysvlufvbppeijvcbwdgyamen/Build/Intermediates/KeyValueObjectMapping.build/Release-iphonesimulator/KeyValueObjectMapping.build/Objects-normal/i386/DCPropertyFinder.o

Building the project, dragging and dropping the .framework into a new project results in this error.

Is there a scheme that could be shared for running the tests? when you first clone this project, you can't verify that the tests work because you don't have the scheme to run them. :)

I am receiving this kind of response from my server

}

How do I parse this ?

Current DCParserConfiguration supports addArrayMapper: and addObjectMapping:
I think it could be nice to introduce addMapper:(id)mapper that supports both object mapping and array mapping in single API. 😄

Hi,

I had a look at your library, and I thing it can help me a lot. But I would like to use it for filling properties of an existing object.

Something like
MyClass *myObject = [[MyClass alloc] init]; NSDictionary *fixture = ...; [myObject parseDictionary:fixture];

But I did not find how to do it? I saw then custom initializer, but I prefer to create directly my instances.

Regards,
Quentin Arnault

Could You please add Tag 1.5 and update the podspec file? It would be nice to download actual version using Cocoapods

Restkit supports multiple datePattern. It would be great to support multiple date patterns as well.

It is mainly needed when parser configurations are merged.

Unix Timestamp is in milliseconds while dateWithTimeIntervalSince1970: takes a NSTimeInterval in seconds. Currently the conversion is 1000x off.

It should be possible to parse an array of objects even if the corresponding value in the dictionary is not an array. A use case is as follows: you parse xml that is designed to be an array but only has a single element. The xml parser has no knowledge of the array intention, and most will just parse this to a dictionary, not an array of one element. This library, however, can actually convert these properly with no additional configuration as it knows the target property is an array type. To clarify further with an example:

This json can be parsed into a user with an array of one tweet:

{
"name": "Diego Chohfi",
"tweets": [
{
"id_str": 190957570511478800,
"text": "Tweet text"
}
]
}

However, this too should be parseable as a user with an array of one tweet (provided you specify an array mapping for property "tweets" of course), but I don't see a way to do it currently:

{
"name": "Diego Chohfi",
"tweets":
{
"id_str": 190957570511478800,
"text": "Tweet text"
}
}

Hey,

In your podspec is written that you support work with CoreData, but in practice I cannot find it in the documentation, nor the tests.

Could you provide a simple example how's that supposed to work?

I thought it would work out of the box, but this is what happens:

MyNSManagedObjectSubclass *contact = [mapping parseDictionary: myDictionary];

in this line I get CoreData: error: Failed to call designated initializer on NSManagedObject class 'MyNSManagedObjectSubclass'.

I know that this in CoreData should look something like:

MyNSManagedObjectSubclass *contact = [NSEntityDescription
                             insertNewObjectForEntityForName:@"MyNSManagedObjectSubclass"
                             inManagedObjectContext:backgroundContext];

.. but I don't know how to populate all the properties in my NSManagedObject with your library.

Thanks,

Kex

It would be nice to have a class like "DCArrayMapping" for NSDictionary, because I have a JSON like this:

{
    "_id":12345,
    "localizedContent":{
        "en":{
            "name":"english name"
        },
        "es":{
            "name":"spanish name"
        }
    }
}

... with an undetermined number of languages, so I'm trying to map it to an object like this:

@interface MyLocalizedContent : NSObject

@property (nonatomic, strong) NSString *name;

@end


@interface MyObject : NSObject

@property (nonatomic, strong) NSNumber *identifier;
@property (nonatomic, strong) NSDictionary *localizedContent;

@end

... and I don't know how to do it without this "DCDictionaryMapping".

The dateFormat is changed to datePattern. Please update the document.

error appears on method:

- (BOOL)canTransformValueForClass:(Class)class;

Expected identifier
Expected ';' after method prototype

In the readme of this github project, we have the following nice and correct example:

DCArrayMapping *mapper = [DCArrayMapping mapperForClassElements:[Tweet class] forAttribute:@"tweets" onClass:[User class]];

But on the website of Cocoapods https://cocoapods.org/pods/DCKeyValueObjectMapping
The same code sample is wrong:

DCArrayMapping *mapper = [DCArrayMapping mapperForClassElements: :[Tweet class] forAttribute:@"tweets"] onClass:[User class]];

There is a useless : before [Tweet class] and and a useless ] after @"tweets"

Edit:
I just found a new error in both this readme and cocoapods:
The following code sample doesn't compile:

DCParserConfiguration *config = [DCParserConfiguration configuration];
[config addArrayMapper:mapper];

DCKeyValueObjectMapping *parser = [[DCKeyValueObjectMapping mapperForClass:[User class] andConfiguration:configuration];
User *user = [parser parseDictionary:jsonParsed];

andConfiguration:configuration must be replaced by andConfiguration:config

The mapper crashes if a NSNull object is passed into DCNSDateConverter

My code looks something like this:

static DCParserConfiguration config;
if ( !config )
    {
        config = [DCParserConfiguration configuration];

        [config addArrayMapper:[DCArrayMapping mapperForClassElements:[UnicomAPIProposalsResponseProposal class]
                                                         forAttribute:@"results"
                                                              onClass:[UnicomAPIProposalsResponse class]]];

        [config addArrayMapper:[DCArrayMapping mapperForClassElements:[UnicomAPIBankProposalsResponseBank class]
                                                         forAttribute:@"results"
                                                              onClass:[UnicomAPIBankProposalsResponse class]]];
    }

    pFunction( resultClass ? [[DCKeyValueObjectMapping mapperForClass:resultClass andConfiguration:config] parseDictionary:responseObject] : responseObject );
...

But results of UnicomAPIBankProposalsResponse becomes UnicomAPIProposalsResponseProposal instead of UnicomAPIBankProposalsResponseBank!

DCAttributeSetter assingValue:forAttributeName:andAttributeClass:onObject:

Line :

[object setValue:value forKey:attributeName]

The issue appear when i work with subclasses of NSManageObject

In DCDynamicAttribute initWithAttributeDescription:forKey:onClass:attributeName:converter:
findTypeName: return @"" because the description of a dynamic property doen't end with the name of the instance variable associated : @"T@"NSString",&,D,N"

I've tried pod 'DCKeyValueObjectMapping' but when I do #import <KeyValueObjectMapping/DCKeyValueObjectMapping.h> the file cannot be found? How am I supposed to use this ? What am I doing wrong here?

Implementation provided may be improved, but it works well for the projects I work on.

1 - Interface

@interface DCParserConfiguration (XBAdditions)

-(void) mergeConfig:(DCParserConfiguration *) parserConfiguration;

@end

2 - Implementation

#import "DCParserConfiguration+XBAdditions.h"
#import "DCArrayMapping.h"


@implementation DCParserConfiguration (XBAdditions)

-(void) mergeConfig:(DCParserConfiguration *) parserConfiguration {

    for (DCObjectMapping * objectMapping in parserConfiguration.objectMappers) {
        DCArrayMapping * arrayMapping = [parserConfiguration arrayMapperForMapper:objectMapping];
        if (arrayMapping) {
            [self addArrayMapper:arrayMapping];
        }
        else{
            [self addObjectMapping:objectMapping];
        }
    }

    for (DCPropertyAggregator * propertyAggregator in parserConfiguration.aggregators) {
        [self addAggregator:propertyAggregator];
    }

    for (DCCustomInitialize * customInitialize in parserConfiguration.customInitializers) {
        [self addCustomInitializersObject:customInitialize];
    }

    for (DCCustomParser * customParser in parserConfiguration.customParsers) {
        [self addCustomParsersObject:customParser];
    }

}

Hello All,

I tried to integrate KVOMapping with Realm but it is giving nil value inside the Realm Object...Please have a look on this...

In the json:
{ "holidayhome": {"home_facilities": [ { "facility_description": "Delivery To Park", } ] } }

In the class:
NSArray *homeFacilities;

Because of the underscore split string, the conversion does not work. It works for everything else, only for arrays of objects it does not work. DCArrayMapping

Here is my little model:

@interface Employee : NSObject

@property (nonatomic, copy) NSString* name;
@property (nonatomic, copy) NSArray* tasks;

@end

@interface Task : NSObject

@property (nonatomic, copy) NSString* title;
@property (nonatomic, copy) NSString* desc;
@end

Now, when using the @synthesizelike

@synthesize tasks = _tasks;

the parser no longer works:

-(void) testCustomMap {

    // set up some "faked JSON parsed Dictionary"
    NSMutableDictionary* task1 = [NSMutableDictionary dictionary];
    [task1 setValue:@"Title1" forKey:@"title"];
    [task1 setValue:@"Description1" forKey:@"desc"];

    NSMutableDictionary* task2 = [NSMutableDictionary dictionary];
    [task2 setValue:@"Title2" forKey:@"title"];
    [task2 setValue:@"Description2" forKey:@"desc"];

    NSMutableDictionary* employee1 = [NSMutableDictionary dictionary];
    [employee1 setValue:@"Matthias" forKey:@"name"];
    [employee1 setValue:[NSArray arrayWithObjects:task1, task2, nil] forKey:@"tasks"];


    DCArrayMapping *mapper = [DCArrayMapping mapperForClassElements:[Task class] forAttribute:@"tasks" onClass:[Employee class]];

    DCParserConfiguration *config = [DCParserConfiguration configuration];
    [config addArrayMapper:mapper];

    DCKeyValueObjectMapping *parser = [DCKeyValueObjectMapping mapperForClass:[Employee class]  andConfiguration:config];


    Employee *matthias = [parser parseDictionary:employee1];


    STAssertEqualObjects(@"Matthias", matthias.name, @"");

    NSLog(@"\n\n\n==>%@\n\n", [[matthias.tasks objectAtIndex:0] class]);

}

The class here is __NSCFDictionary. When using the @synthesize with out applying a value to it, like

@synthesize tasks;

The class is Task

I can't mapping id param in JSON to calendar_id in Calendar object.

accessRole = owner;

colorId = 16;
defaultReminders = (
