iPhone - 将视频作为闪屏展示

Question

我需要在我的iPhone应用程序中展示视频作为启动画面，我正在使用以下代码：

-(void)setupMovie{
NSString* moviePath = [[NSBundle mainBundle] pathForResource:@"iphone" ofType:@"mp4"];
NSURL* movieURL = [NSURL fileURLWithPath:moviePath];

playerCtrl =  [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
playerCtrl.scalingMode = MPMovieScalingModeFill;
playerCtrl.controlStyle = MPMovieControlStyleNone;
playerCtrl.view.frame = CGRectMake(0, 0, 480, 320);

[[NSNotificationCenter defaultCenter] addObserver:self 
                     selector:@selector(moviePlayBackDidFinish:) 
                              name:MPMoviePlayerPlaybackDidFinishNotification object:nil];

[playerCtrl.view setCenter:CGPointMake(240, 160)];
[playerCtrl.view setFrame:CGRectMake(0, 0, 480, 320)];
[playerCtrl.view setTransform:CGAffineTransformMakeRotation(-M_PI/2)];
[self.window addSubview:playerCtrl.view];
[playerCtrl play];}

但是播放器视图并没有从x=0，y=0的位置开始。原因是什么，怎样修复呢？ 它是从x=100，y=100（大约）开始的。

旋转后设置框架：

playerCtrl.view.frame = CGRectMake(0, 0, 320, 480);

Answer 2

您正在设置影响位置的信息三次

playerCtrl.view.frame = CGRectMake(0, 0, 480, 320);
[playerCtrl.view setCenter:CGPointMake(240, 160)];
[playerCtrl.view setFrame:CGRectMake(0, 0, 480, 320)];

所以一个接一个地尝试
