show blank page after presented in form sheet style on Swift iPad App

[wjiuxing]

I have a Swift project. I want to present this picker in form sheet on iPad. But it shows me a blank view, see screenshot at the end pls.

Steps to reproduce: 0- I'm using Xcode 7.1.1 1- new a Master-Detail Application in Swift 2- add CTAssetsPickerController to Podfile and run pod install 3- change the MasterViewController

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        PHPhotoLibrary.requestAuthorization({ (status) -> Void in
            dispatch_async(dispatch_get_main_queue(), { () -> Void in
                // init picker
                self.assetsPicker = CTAssetsPickerController()

                // set delegate
                self.assetsPicker.delegate = self

                // set default album (Camera Roll)
                self.assetsPicker.defaultAssetCollection = .SmartAlbumUserLibrary

                if UIDevice.currentDevice().userInterfaceIdiom == .Pad {
                    self.assetsPicker.modalPresentationStyle = .FormSheet
                }

                // present picker
                self.presentViewController(self.assetsPicker, animated: true, completion: nil)
            })
        })
   }

4- run the app and add an entry by clicking on the "+" on the right bar button of MasterViewController 5- click on the new cell inserted above. At this time above code will be called. 6- show a blank page as the image following.

Thank you very much. :)

I did above steps with an Objective-C project. And I found the code works well in Objective-C. But I haven't done anything else but translate the code from Swift to Objective-C. I think there may be bugs in Swift.

 - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

   [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
       dispatch_async(dispatch_get_main_queue(), ^{

         // init picker
         CTAssetsPickerController *picker = [[CTAssetsPickerController alloc] init];

         // set delegate
         picker.delegate = self;

         // set default album (Camera Roll)
         self.assetsPicker.defaultAssetCollection = PHAssetCollectionSubtypeSmartAlbumUserLibrary;

         // to present picker as a form sheet in iPad
         if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
              picker.modalPresentationStyle = UIModalPresentationFormSheet;
         }

         // present picker
         [self presentViewController:picker animated:YES completion:nil];
       });
    }];
}

Hi, I just wanted to share: I've been experiencing the same issue. I tried not using the defaultAssetCollection property, and that fixed it. Any ideas why?

Thanks

I'm getting the same blank screen, but in an Objective-C project. Trying to get my head around it. Did you fix this?
