默认情况下全屏播放视频 [英] Play video by default in full screen

问题描述

我正在使用MPMoviePlayerController播放视频：

I am playing a video by using MPMoviePlayerController:

NSString *urlStr = [[NSBundle mainBundle] pathForResource:@"myvideo.MOV" ofType:nil];
NSURL *url = [NSURL fileURLWithPath:urlStr];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
[self.view addSubview:moviePlayer.view];
moviePlayer.view.frame = CGRectMake(0,0, 1024, 675);  
[moviePlayer play];

但要求是默认情况下视频应全屏显示，当我最小化时，应该在上面帧大小。

But requirement is that by default video should be in full screen and when I minimize it should be in above frame size.

请帮帮我。

试试这个。

#define degreesToRadian(x) (M_PI * (x) / 180.0)

-(void)playMovieAtURL:(NSURL*)movieURL
{
    if ([NSClassFromString(@"MPMoviePlayerController") instancesRespondToSelector:@selector(view)])
    {

        // running iOS 3.2 or better
        mViewPlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
        mViewPlayer.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;

        CGRect newFrame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
        mViewPlayer.view.frame = newFrame;

        CGAffineTransform landscapeTransform;
        landscapeTransform = CGAffineTransformMakeRotation(degreesToRadian(90));
        landscapeTransform = CGAffineTransformTranslate(landscapeTransform, 80, 80);

        [mViewPlayer.view setTransform: landscapeTransform];

        [self.view addSubview:mViewPlayer.view];

        [mViewPlayer.moviePlayer play];
