A Facebook image picker providing a simple UI for a user to pick photos from a users Facebook account. It provides an image picker interface that matches the iOS SDK's UIImagePickerController.
It takes care of all authentication with Facebook as and when necessary. It will automatically renew auth tokens or prompt the user to re-authorize the app if needed.
- Xcode 6 and iOS SDK 7
- iOS 7.0+ target deployment
- FBSDKCoreKit, FBSDKLoginKit (>= 4.0)
CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like the Kite Print SDK in your projects. If you're using it just add the following to your Podfile:
pod "FacebookImagePicker"You need to have set up your application correctly to work with Facebook as per https://developers.facebook.com/docs/ios/getting-started
To launch the Facebook Image Picker:
#import <OLFacebookImagePickerController.h>
OLFacebookImagePickerController *picker = [[OLFacebookImagePickerController alloc] init];
picker.delegate = self;
[self presentViewController:picker animated:YES completion:nil];Implement the OLFacebookImagePickerControllerDelegate protocol:
- (void)facebookImagePicker:(OLFacebookImagePickerController *)imagePicker didFinishPickingImages:(NSArray/*<OLFacebookImage>*/ *)images {
[self dismissViewControllerAnimated:YES completion:nil];
// do something with the OLFacebookImage image objects
}
- (void)facebookImagePickerDidCancelPickingImages:(OLFacebookImagePickerController *)imagePicker {
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)facebookImagePicker:(OLFacebookImagePickerController *)imagePicker didFailWithError:(NSError *)error {
// do something with the error such as display an alert to the user
}
Xcode 7 and iOS 9 includes some new security features. In order to connect to Facebook you will need to add some more exceptions to your project's info plist file (in addition to the ones that your project might require). We need to add forward secrecy exceptions for Facebooks's CDNs. The following is what you need to copy your app's info plist, which includes anything that is needed by Kite as well:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSExceptionDomains</key>
<dict>
<key>akamaihd.net</key>
<dict>
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
<key>NSIncludesSubdomains</key>
<true/>
</dict>
<key>facebook.com</key>
<dict>
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
<key>NSIncludesSubdomains</key>
<true/>
</dict>
<key>fbcdn.net</key>
<dict>
<key>NSExceptionRequiresForwardSecrecy</key>
<false/>
<key>NSIncludesSubdomains</key>
<true/>
</dict>
</dict>
</dict>
Set maximum number of selections
Limit the number of assets to be picked.
- (BOOL)facebookImagePicker:(OLFacebookImagePickerController *)imagePicker shouldSelectImage:(OLFacebookImage *)image
{
// Allow 10 assets to be picked
return (imagePicker.selected.count < 10);
}The project is bundled with a Sample App to highlight the libraries usage. Alternatively you can see the library in action in the following iOS apps:
