为了解决在MPMovieController上添加一个和控制栏一起显示的按钮，特别研究了一下MPMoviePlayerController的结构 (controlStyle是default,为了便于查看，省去了部分输出):
(lldb) po [m_view recursiveDescription]
(id) $1 = 0x179529f0 <UIView: 0xfdb55f0; frame = (0 0; 604 256); layer = <CALayer: 0xfd83a10>>
| <MPMovieView: 0xde71d70; frame = (0 0; 604 256);
| | <MPSwipableView: 0x1d774dc0; frame = (0 0; 604 256);
| | | <MPVideoBackgroundView: 0x1d775160; frame = (0 0; 604 256);
| | | | <UIView: 0x1d776160; frame = (0 0; 604 256);
| | | | <MPVideoView: 0x1d7740e0; frame = (0 0; 604 256);
| | | | | <UIView: 0x1d773fc0; frame = (142 -32; 320 320);
| | | | | | <MPVideoBufferLayerContainer: 0x1d772050> (layer)
| | | | | | | <MPVideoBufferLayer: 0x22ebdb20> (layer)

| | | | | | | | | <FigVideoLayer: 0xdbaab80> (layer)
| | | | | | | | <AVPlayerLayerSubtitleLayer: 0x22eaf480> (layer)
| | | | | | | | | <AVSubtitleTextLayer: 0x22ea70f0> (layer)
| | | | <MPInlineVideoOverlay: 0x1d77e7c0; frame = (0 0; 604 256);
| | | | | <MPInlineTransportControls: 0x1d77edc0; frame = (0 212; 604 44);
| | | | | | <MPDetailSlider: 0x1d7837c0; baseClass = UISlider; frame = (70 12; 475 24);
| | | | | | | <UILabel: 0x1d78e1b0; frame = (-8 -2; 45 25); text = '0:00';
| | | | | | | <UILabel: 0x1d78e240; frame = (438 -2; 45 25); text = '-0:00';
| | | | | | | <UIImageView: 0x1d78e300; frame = (68 5; 360 11);
| | | | | | | <UIImageView: 0x1d78e3a0; frame = (47 5; 21 11);
| | | | | | | <UIImageView: 0x1d78c7e0; frame = (47 6; 381 10);
| | | | | | | <UIImageView: 0x1d78e430; frame = (57 2; 22 21);
| | | | | | <MPTransportButton: 0x1d785a50; baseClass = UIButton; frame = (34 14; 16 18);
| | | | | | | <UIImageView: 0x1d785c70; frame = (0 0; 16 18);
| | | | | | | <UIImageView: 0x1d785bb0; frame = (-42 -41; 100 100);
| | | | | | <MPTransportButton: 0x1d785dd0; baseClass = UIButton; frame = (564 16; 13 14);
| | | | | | | <UIImageView: 0x1d785ff0; frame = (0 0; 13 14);
| | | | | | | <UIImageView: 0x1d785f30; frame = (-43.5 -43; 100 100);
| | | | | | <UILabel: 0xde72ce0; frame = (265 13; 74 19); text = 'Loading…';
| | | | | | <UIActivityIndicatorView: 0xde730d0; frame = (239 12; 20 20);
| | | | | | | <UIImageView: 0xde77e90; frame = (0 0; 20 20);
| | | | | <MPNowPlayingItemQueueInfoButton: 0x1d786690; baseClass = UIButton; frame = (251 10; 103 23);
| | | | | | <UIImageView: 0x1d786750; frame = (0 0; 103 23);
| | | | | | <UIButtonLabel: 0x1d788a50; frame = (0 0; 0 0);MPInlineVideoOverlay是显示控制栏的浮动view。Touches事件的获取要基于MPVideoBackgroundView进行处理。其中两个MPTransportButton分别是播放和全屏按钮。
对于事件获取，可以使用添加一个UITapGestureRecognizer的方式，不过这种方式会导致原来的操作失效，因为相关的事件被拦截了。另外一种简单的方式是向现有的UITapGestureRecognizer添加一个target即可,这样不会打乱原先的消息传递:
-(void) addTargetActionToGesture:(UIView *)view
{
NSArray * gestureGroup = [view gestureRecognizers];
for(UITapGestureRecognizer * g in gestureGroup)
{
[g addTarget:selfaction:@selector(handleMoviePressed:)];
}
}
*iOS 6.0同之前的版本有所不同，事件必须绑定在MPVideoBackgroundView上。如果以UITapGestureRecognizer进行判断处理更为有效。
