iphone - iPhone-将视频显示为初始屏幕

我需要在iPhone应用程序中将视频显示为初始屏幕
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];}

但是玩家视图不是从x = 0，y = 0的位置开始的。是什么原因以及如何修复它。
它的起始x = 100，y = 100（大约）。

最佳答案

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
