copied!<p>Hey guys, I finally resolve my problem. I subclassed <code>UIView</code> and added two <code>UIImageView</code>s and an <code>UIButton</code> to it. The animation is perfectly good now!</p> <p>Here is the code:</p> <p>.h</p> <pre><code>#import <UIKit/UIKit.h> @interface NNAnimatableButton : UIView { UIImageView *backgroundImageView; UIImageView *imageView; UIButton *button; } @property (nonatomic, retain) UIImageView *backgroundImageView; @property (nonatomic, retain) UIImageView *imageView; @property (nonatomic, retain) UIButton *button; @end </code></pre> <p>.m</p> <pre><code>#import "NNAnimatableButton.h" @implementation NNAnimatableButton @synthesize backgroundImageView, imageView, button; - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { CGRect rect = CGRectMake(0.0f, 0.0f, frame.size.width, frame.size.height); NSUInteger autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleBottomMargin; // Initialization code. backgroundImageView = [[UIImageView alloc] initWithFrame:rect]; backgroundImageView.autoresizingMask = autoresizingMask; imageView = [[UIImageView alloc] initWithFrame:rect]; imageView.autoresizingMask = autoresizingMask; imageView.contentMode = UIViewContentModeCenter; button = [UIButton buttonWithType:UIButtonTypeCustom]; button.autoresizingMask = autoresizingMask; [button setFrame:rect]; [self addSubview:backgroundImageView]; [self addSubview:imageView]; [self addSubview:button]; [backgroundImageView release]; [imageView release]; } return self; } - (void)dealloc { [backgroundImageView release]; [imageView release]; [button release]; [super dealloc]; } @end </code></pre>
