更改 MPMoviePlayerController 实例的视频 url，而不是分配新的

Question

我有一个名为 myMoviePlayer 的 MPMoviePlayerController；我在应用程序加载时分配并初始化它：

NSString *moviePath = [bundle pathForResource:[movieName uppercaseString] ofType:@"mov" inDirectory:@"Videos"];

if(moviePath)
{
    NSURL *movieURL = [NSURL fileURLWithPath:moviePath];

    myMoviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:movieURL];
    [**myUI.view** setFrame:CGRectMake(80, 80, 600, 350)];
    [self.view addSubview:myMoviePlayer.view];
    myMoviePlayer.shouldAutoplay=NO;
}

我的应用程序中有两个名为 imageView 和 videoView 的视图。我需要在 imageView 中隐藏 myMoviePlayer 并在我的 UI 视图为 videoView 时再次显示它。

每次放映电影时，movieName 都会不同。

现在，每次我的视图更改为电影视图时，我都会分配并初始化 myVideoPlayer 。是否可以将新的视频 url 设置为 myMoviePlayer 而无需再次分配？

Answer 1

是的，有：

[myMoviePlayer setContentURL:[NSURL URLWithString:aMovieUrl]];

只需设置 contentURL 属性 href="http://developer.apple.com/library/ios/#documentation/mediaplayer/reference/MPMoviePlayerController_Class/Reference/Reference.html" rel="noreferrer">MPMoviePlayerController 实例。

Sharmain 我遇到了你的问题...
您需要设置 contentURL，然后调用 mpmovieplayercontroller 的 Play 方法：

[myPlayer setContentURL:xyz];
[myPlayer play];

NSString *path = [[NSBundle mainBundle] pathForResource:@"myVideo" ofType:@"mp4"];   
self.myPlayer = [[MPMoviePlayerController alloc] init];
self.myPlayer.view.frame = CGRectMake(0, 124, 768, 900); 
self.myPlayer.shouldAutoplay = YES;
self.myPlayer.controlStyle = MPMovieControlStyleNone;
self.myPlayer.repeatMode = MPMovieRepeatModeOne;
self.myPlayer.fullscreen = YES;
self.myPlayer.movieSourceType = MPMovieSourceTypeFile;
self.myPlayer.scalingMode = MPMovieScalingModeAspectFit;
[self.view addSubview:myPlayer.view];

[myPlayer setContentURL:[NSURL fileURLWithPath:path]];
[myPlayer play];
