My app calls iOS' native MPMediaPicker during music selection for its playlist.
Code:
// show media picker
MPMediaPickerController *picker =
[[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic];
picker.delegate = self;
picker.allowsPickingMultipleItems = YES;
[self presentViewController:picker animated:YES completion:nil];
But during the selection, which is below screen:
when you tap on the "+" buttons of songs, the button doesn't animate (like becoming grey, highlighted, etc), so the user has no feedback that the button was successfully tapped.
I did not observe this in iOS 7.0, but after I upgraded to iOS 8, this problem showed up.
How can I solve it?
After upgrading to iOS 9, I noticed that the problem was fixed (at least for my app).
