I added this line: self.backgroundImageView = [[UIImageView alloc] init]; above the backgroundImages.animationImages array since I thought i'm not allocating memory for the backgroundImageView object. Now the main bug doesn't appear, but now the problem is that the crystal ball won't animate. Any solutions?
