Like in Flipboard loading view, there is a dismiss button to cancel the loading.

Hi,
I have used JGProgressHUD to show loading progress on login page. When user input wrong user/password, then i want to show error message using JGProgressHUDErrorIndicatorView.
But it occurs error:
2014-09-04 16:15:30.734 SPS[3839:60b] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'HUD is currently transitioning'

How can i solve this problem?
Thanks.

This is the only message i get:

Failed to read file or folder at /private/var/folders/mp/1x8f09w51rz2ghkxy3zkglwc0000gn/T/carthage-archive.w4JYoc/__MACOSX/JGProgressHUD.framework

PLS HALP!

It seems should add observer for UIKeyboardDidHideNotification, and reset keyboardFrame to CGRectZero in the callback

Hi Jonas

Found another issue.

I've got a "portrait-only" ViewController, which is called from a normal (portrait and landscape) ViewController. Now when I am in landscape mode and go to the portrait-only ViewController, the ProgressHUD is displayed quite wrong.. This issue also appears while changing orientation.

Thanks for your great code anyway. It's a very cool HUD :)

Hi, thanks for making this awesome piece of UI.

The current behavior of JGProgressHUD due to the NSAsserts is that it will crash when

• showInView is called but it is already on view
• dismiss is called but it is not on view

I wonder if such situations can be better handled by simply ignoring the command and produce a warning message, instead of immediately crashing the program. Is there any disadvantage in doing so?

I'll be happy to make a pull request if you think this is a good idea.

I'm experiencing a crash in 1.4 on a iOS 10 device that says:

-[UIView setEffect:]: unrecognized selector sent to instance

I don't see anywhere in the source where setEffect is being used. Any clue?

Sorry for bothering you again.
Current HUD transition between states without text and with some text/details (and when changing visible text/details values) does not really look good -
text/detail labels are floating over the HUD borders. Is it possible to somehow fix these transitions (to make text labels appearing from the center of HUD and not crossing the HUD borders)?
Here is the example video: http://youtu.be/IVEkKvK_wRs
Thanks.

ERROR ITMS-90087: "Unsupported Architectures. The executable for xxx.app/Frameworks/JGProgressHUD.framework contains unsupported architectures '[x86_64, i386]'."

I notice that when device is moved around, the hud moves as well, mimicing the parallax on iOS backgrounds.
I suggest allowing an option to enable/disable that named something like "enableParallaxEffect".
Additionally it may be good to provide a mode of 3 types:

• Off: Parallax always off
• Device: Parallax is based on whether user has reduce motion turn off/on http://stackoverflow.com/a/25453082/4698501
• On: Parallax always on

Hello! Have a question.
For some reason I prefer not to dismiss keyboard while showing HUD and seeking the simple way to deny user possibility of pressing the keyboard buttons while making some network request in background.
Is it possible to somwhow display HUD to cover the visible keyboard?
Thanks!

Hi,

You should remove or catch the asserts in the show and hide methods. It's not cool that the app crashes if you try to show a HUD twice. It should just fail gracefully.

Hi, So I've integrated the library through cocoapods, and I'm having a pure swift project, XCode 6.3.. really didn't change anything.. any thoughts?
P.S: I'm importing in my swift file using the swift import JGProgressHUD, not through bridging header.. (which btw, I can't import it through bridging header alone)..
I don't know if that's enough information.. the library is working fine really, just the images are not loading apparently from the resources bundle, everything else is fine...

If you have HUD with JGProgressHUDInteractionTypeBlockAllTouches the tapBlock are actually triggered, otherwise they are not. This is not corresponding with documentation.

Hi, congratulations for the work.

My application crashes when running in iOS 7 before did not happen.

Use CocoaPods with JGProgressHUD version: 1.3.4

if (iOS7) {
            [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(updateMotionOnHUDView) name:UIAccessibilityReduceMotionStatusDidChangeNotification object:nil];
        }

Thank you for your prompt reply.

Hello! This HUD looks very nice and promising. But as I can see it doesn't update position properly on screen rotations (and when keyboard appears). Would be great to have such feature. Thanks!

When trying to build the framework using Carthage v0.7.5, I see the following:

*** Checking out JGProgressHUD at "v1.2.7"

but nothing similar to this:

*** Building scheme "JGProgressHUD" in JGProgressHUD.xcworkspace

and afterwards there is no JGProgressHUD framework in Carthage's Build folder either. Can you reproduce this issue?

can not support bitcode ?

How to make a progress bar when the progress bar shows that it can be operation interface, because when a progress bar pops up, now he can only wait for, and can't do any operation, thank you

I like this code!
But , I want to run some code after progressHUD dismissed, Could add some block after JGProgressHUD dismissed ?
I think this feature is very useful !
Thank you.

Hi,

Great library. however, I get this crash every now and again: Fatal Exception : NSINternalInconsistencyException (HUD is currently transitioning)

The culprit line is JGProgressHUD.m line 384 - [JGProgressHUD showInRect:inView:animated:]

First of all, I really enjoy this control. Excellent work.

I do have one issue/question. In order to prevent the user from interacting with views behind the HUD, I understand I need to set the userInteractionEnabled property. However, in order to disable interaction I have to set userInteractionEnabled = YES. In plain English that reads to me that I have set the user interaction enabled property to YES thereby allowing interaction which is actually the opposite of what I have done.

Hope this makes sense. It seems that I should set this property to NO in order to disable user interactions with background views.

The frame of the animated circular loading indicator flickers for this style on iOS 9.3

It seems to loose the padding when I do so.

JGProgressHUD *HUD = [JGProgressHUD progressHUDWithStyle:JGProgressHUDStyleLight];
HUD.indicatorView = nil;
[HUD.contentView addSubview:[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"hud-saved"]]];
[HUD showInView:self.view];

Results in:

Weirdly enough this works, though with a warning:

JGProgressHUD *HUD = [JGProgressHUD progressHUDWithStyle:JGProgressHUDStyleLight];
HUD.indicatorView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"hud-saved"]];
[HUD showInView:self.view];

var hud:JGProgressHUD = JGProgressHUD(style:JGProgressHUDStyle.ExtraLight)
hud.indicatorView = nil

gives the error:
'JGProgressHUD' does not have a member named 'indicatorView'

I want to change the height of view.

thank you .

There is an issue with this on carthage when using archive builds of a project using the created framework, You can check out this link Carthage/Carthage#53 for more detail. Basically you need to add user-defined-setting of "BITCODE_GENERATION_MODE" set to "bitcode" in the framework project before it will be able to work from a carthage builds. I have already cleared this with the guys at Alamofire and it works.

Now we have three styles JGProgressHUDStyleExtraLight, JGProgressHUDStyleLight and JGProgressHUDStyleDark.
How can I create a HUD with clear background color?

like this:

• (void)show;
• (void)showWithMaskType:(SVProgressHUDMaskType)maskType;
• (void)showWithStatus:(NSString*)string;
• (void)showWithStatus:(NSString*)string maskType:(SVProgressHUDMaskType)maskType;

[SVProgressHUD show];
[SVProgressHUD dismiss];

it will automatically add hud to window.

and Great Thanks to your wonderful work.

Is there a way to dismiss the hud with a completion block? I need to dismiss the hud (animated) on a modal controller, and once the hud is completely dismissed, I need to dismiss the modal controller. Right now, when I try to dismiss the hud and then the modal controller without this method, I get the error: "HUD is not visible" because the modal gets dismissed before the hud gets dismissed.

Hi Jonas

The font in the progress hud seems a bit blurry..

I already changed the font and frame size, but something seems to be wrong.

Thanks

We're currently missing default implementation of success and failure indicator, they only exists in the example project. Maybe we can make them available in the library?

This is a really nice library, but it is not effective to rely on targetView.userInteractionEnabled to completely block interaction with the UI. For example if the view contains a child view controller via an embed segue, the child view controller's interaction does not appear to be blocked by userInteractionEnabled. A better approach would be to place a transparent overlay view over the entire target view and block interaction with that. I will see if I can get this implemented myself.

Noticed the following bug when moving the device with the hud present.
Seems to be a problem caused by clipping.
Using Swift and added it to an empty view controller.

    override func viewDidLoad() {
        super.viewDidLoad()

        view.backgroundColor = UIColor.blackColor()

        let hud = JGProgressHUD(style: .ExtraLight)
        hud.showInView(view)
    }

Initial presentation

Having moved the device

If you call dismiss on the HUD more than once (for any number of reasons) it bumps into the the NSAssert for self.targetView. It seems more practical to ignore the calls to dismiss rather than allowing it to continue in and crash.

As iOS 8 supports dynamic libraries, it will be great if there can be a dynamic version of this library. Then it can be installed using Carthage for example, and I think that's more friendly than a static library.

Hi, first of all — thanks for awesome lib that you've made!

Unfortunately, i've faced an issue with it :(

Version: 1.3.1
iOS versions: 8&9. Both simulator & device.

Flow:

1. present HUD in UIViewControllers view
2. push another view controller to navigation stack
3. rotate device
4. go back to previous controller
5. observe wrong position for HUD

I've made small project which shows the issue: https://github.com/Austinate/JGProgressHudIssue
You can run UI test testRotation and see what's happening. Sorry if test is bad or it's code smells, it was my first experience with XCTest UI testing 😭

Image that shows issue.

As i see what's happening — view controllers view bounds doesn't change on rotation if controller wasn't presented on screen during rotation.

I'm not sure if it's actually any implementation issue for JGProgressHUD (since it's accessing view bound as supposed to do), but i'd like to receive any advice that can help me, thanks!

Update

I was able to fix issue described in ticket, but than i've found that in my case that it still wasn't working so good. What i have: https://imgflip.com/gif/tew5o (gif)

I've updated test project with proper code to reproduce my issue. What happens: i show spinner in viewWillAppear and hide it after some networking stuff is done. So while appearing animation of HUD is in progress — frame change isn't happening because of this code:

if (_transitioning) {
        _updateAfterAppear = YES;
        return;
    }

So here comes question: will there be any UI issues if we'd let it to change frame during appear or there was some another reason why this code was added?

                    })
            })
        }

    }

any solution?

Thanks for the work, it looks like a great library. I was wondering if you could have this added to Cocoapods.org so I can add it to my project and allow my developers to update easily.

It seems that the interactionType handling should be reversed. I would assume BlockNoTouches would mean that no touches would be blocked, but in this case, every touch is blocked as seen by the hittest code.

if (self.interactionType == JGProgressHUDInteractionTypeBlockNoTouches) {
    return nil;
}
else {
    UIView *view = [super hitTest:point withEvent:event];

    if (self.interactionType == JGProgressHUDInteractionTypeBlockAllTouches) {
        return view;
    }
    else if (self.interactionType == JGProgressHUDInteractionTypeBlockTouchesOnHUDView && view != self) {
        return view;
    }

    return nil;
}

I was using cocoa pods to install JGProgressHUD: pod 'JGProgressHUD'.
However, when compiling the project, I kept getting error msg as bellowing.
Any fix or suggest?

     "_OBJC_CLASS_$_JGProgressHUDSuccessIndicatorView", referenced from:

Hi Jonas, any plans for iOS9?

Cheers, Flavio

hello, is add to swift project? Thank you.

I would like to see an option for setting a grace period. I have subclassed JGProgressHUD for one of my projects. Maybe you want to implement something similar?

import "JGProgressHUD.h"

@interface FSProgressHUD : JGProgressHUD

@Property NSNumber* graceTime;
@Property BOOL taskInProgress;
@Property BOOL showInSuperview;

• (void)showInView:(UIView*)view;
• (void)dismiss;

@EnD

import "FSProgressHUD.h"

@interface FSProgressHUD ()

@Property NSTimer* graceTimer;
@Property UIView* view;

@EnD

@implementation FSProgressHUD

/**
Shows the HUD animated. You should preferably show the HUD in a UIViewController's view.
@param view The view to show the HUD in. The frame of the @c view will be used to calculate the position of the HUD.
*/

• (void)showInView:(UIView*)view
  {
  if (_graceTime && [_graceTime doubleValue] > 0.0) {
  _view = view;
  _taskInProgress = YES;
  _graceTimer = [NSTimer scheduledTimerWithTimeInterval:[_graceTime doubleValue] target:self
  selector:@selector(handleGraceTimer:)
  userInfo:nil
  repeats:NO];
  }
  else {
  [super showInView:view];
  }
  }
• (void)dismiss
  {
  _taskInProgress = NO;
  [super dismiss];
  }
• (void)handleGraceTimer:(NSTimer*)theTimer
  {
  if (_taskInProgress) {
  if (_showInSuperview && _view.superview) {
  [super showInView:_view.superview];
  }
  else {
  [super showInView:_view];
  }
  }
  }

@EnD

please add a property like MBProgressHUD opacity background
HUD.dimBackground = YES;
