在写的时候，把问题想复杂化了。后来发现系统自带的
MediaPlayer/MediaPlayer.h
配合简单的动画就可以完成这个登录界面。并没有什么难度。
需要注意的是 视频控制器的几个属性。
_moviePlayer.repeatMode=MPMovieRepeatModeOne;
_moviePlayer.shouldAutoplay=YES;
[_moviePlayersetFullscreen:YES];
[_moviePlayersetScalingMode:MPMovieScalingModeAspectFill];
[_moviePlayersetControlStyle:MPMovieControlStyleNone];
- (void)viewDidLoad {
[superviewDidLoad];
NSString* path = [[NSBundlemainBundle]pathForResource:@"mp4"ofType:@"mp4"];
_movieURL= [NSURLfileURLWithPath:path];
[selfreadyPlayer];
