MPMoviePlayerController 背景颜色不会粘住
我的代码是这样的。
NSString *path = [[NSBundle mainBundle] pathForResource:@"movie_files" ofType:@"m4v"];
NSURL *videoURL = [NSURL fileURLWithPath:path];
moviePlayer = [[MPMoviePlayerController alloc]
initWithContentURL:videoURL];
//setting
moviePlayer.scalingMode =MPMovieScalingModeAspectFit;
moviePlayer.controlStyle=MPMovieControlStyleDefault;
moviePlayer.shouldAutoplay=NO;
[moviePlayer.view setFrame:CGRectMake(20, 20, 280, 200)];
//notification
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePlayBackDidFinish:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayer];
//clearColor
UIView *subV =[[UIView alloc]init];
for(subV in moviePlayer.backgroundView.subviews) {
subV.backgroundColor = [UIColor clearColor];
}
[moviePlayer.view addSubview:subV];
[self.view addSubview:moviePlayer.view];
//show white screen
Please tell the clear background way.

You need to change it to:
您需要将其更改为：
moviePlayer.backgroundView.backgroundColor = [UIColor clearColor];
for(UIView *aSubView in moviePlayer.view.subviews) {
aSubView.backgroundColor = [UIColor clearColor];
}

Setting Background view's color alone didn't work for me.
单独设置背景视图的颜色对我不起作用。
I think the view background color should also be changed. I added one more line of code and now it woks fine. The entire video background is transparent now. :) Thanks @Jordi
我认为视图背景颜色也应该改变。我又添加了一行代码，现在一切正常。整个视频背景现在是透明的。:) 谢谢@Jordi
moviePlayer.backgroundView.backgroundColor = [UIColor clearColor];
moviePlayer.view.backgroundColor = [UIColor clearColor];
for(UIView *aSubView in moviePlayer.view.subviews) {
aSubView.backgroundColor = [UIColor clearColor];
}

another option is to hide the video player and then show it when it is ready to display
另一种选择是隐藏视频播放器，然后在准备好显示时显示它
