Release Notes

Minimum Requirement

iOS 9 SDK

Adding to your project

  1. CocoaPods Podfile

    platform :ios, '8.0'
pod 'CTAssetsPickerController',  '~> 3.0.0'

  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.
}

Customisation

Customisation can be done by setting properties or implementating delegate methods. See the demo project for the details.

Localisation

CTAssetsPicker.strings contains strings used in the picker. It will be included in CTAssetsPickerController.bundle automatically if you add the picker to your project by CocoaPods. You might translate the text or add your translation accordingly. PR is always welcomed if you add translation to the picker.

App Extensions

When using CTAssetsPickerController in an App Extension, #define CT_APP_EXTENSIONS to avoid using unavailable APIs.

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];

Documentation

Note

CTAssetsPickerController does not compress the picked photos and videos. You can retrieve the image or video data of picked assets by the PHImageManager object. Please refer the documentation of PHImageManager.
