Minimum Requirement

iOS 9 SDK, Minimum Deployment Target iOS 8.0

Adding to your project

1. CocoaPods Podfile

   platform :ios, '8.0'
   pod 'CTAssetsPickerController',  '~> 3.3.0'
   

2. Manual Setup

Usages

1. Import header

   #import <CTAssetsPickerController/CTAssetsPickerController.h>

2. Create and present CTAssetsPickerController

   // request authorization status
   [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status){
       dispatch_async(dispatch_get_main_queue(), ^{
           
           // init picker
           CTAssetsPickerController *picker = [[CTAssetsPickerController alloc] init];
       
           // set delegate
           picker.delegate = self;
           
           // Optionally present picker as a form sheet on iPad
           if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
               picker.modalPresentationStyle = UIModalPresentationFormSheet;
           
           // present picker
           [self presentViewController:picker animated:YES completion:nil];
       });
   }];

3. Implement didFinishPickingAssets delegate

   If the picker is presented by presentViewController:animated:completion: method, the delegate is responsible for dismissing the picker when the operation completes.

   - (void)assetsPickerController:(CTAssetsPickerController *)picker didFinishPickingAssets:(NSArray *)assets
   {
   // assets contains PHAsset objects.
   }

Questions, Issues and Suggestions

Please check with wiki and issues for common issues and questions. Please open a [new Issue] (https://github.com/chiunam/CTAssetsPickerController/issues/new) if you run into a problem specific to the picker. Bug reports and pull requests are always welcome.

Bonus

You may reuse the preview feature of the picker to view any assets. Just init a CTAssetsPageViewController with an array of assets and assign pageIndex property. Please refer to the demo app for the details.

NSArray *assets = @[asset1, asset2, asset3, ...];
CTAssetsPageViewController *vc = [[CTAssetsPageViewController alloc] initWithAssets:assets];
vc.pageIndex = assets.count - 1; // display the last asset 

[self.navigationController pushViewController:vc animated:YES];
