You better should use an autoreverse and looped animation, cause creating animations over and over will fulfill the phone memory.

With this code, only one animation is retained.

view.transform = CGAffineTransformMakeRotation(-kDeleteAnimationAmplitude);

[UIView animateWithDuration:0.1 delay:0 options:UIViewAnimationOptionRepeat|UIViewAnimationOptionAutoreverse animations:^{
    view.transform = CGAffineTransformMakeRotation(kDeleteAnimationAmplitude);
} completion:nil];

Then if you want to stop your animation, just call:

[view.layer removeAllAnimations];

I have done this using CGAffineTransformMakeRotation. Don't know there is some other better method. But What I have done is my logic you can copy that as it is and you just need to add a delete button on the left top of that view. In the following code I am just animating the thumbnail or any view just like iPad does on its home screen. One thing, You need to declare int direction globally. and every time when you will call this method you will set direction = 1; 

    -(void)shakeToDelete:(UIView *)shakeMe
{

    [UIView animateWithDuration:0.1 animations:^
     {
         shakeMe.transform = CGAffineTransformMakeRotation(0.05 * direction);
     }
                     completion:^(BOOL finished)
     {

         direction = direction * -1;
         [self shakeToDelete:shakeMe];
     }];
 }

/// edit I tried this way and got it working in my sample screen as attached in photo enter image description here
