Question

我无法在MPMovieplayercontroller中播放电影。我在谷歌搜索了很多，但每次我都有黑屏。我也尝试检查isPreparedToPlay属性，但它总是错误的。

self.moviePlayer = [[MPMoviePlayerController alloc] init];

[self.moviePlayer setContentURL:[self.videos objectAtIndex:0]];
NSLog(@"Playing videos : %@", [self.moviePlayer contentURL]);

 NSLog(@"Playing videos : %@", [[self.moviePlayer contentURL] absoluteString]);

[self.moviePlayer.view setFrame:CGRectMake (0, 0, 320, 460)];
[self.view addSubview:self.moviePlayer.view];
//self.moviePlayer.movieSourceType    = MPMovieSourceTypeFile;
/*[self.moviePlayer.view setFrame:self.view.bounds];
[self.moviePlayer prepareToPlay];
[self.moviePlayer setShouldAutoplay:NO];*/  
[self.moviePlayer play];

第一个NSLog打印出一些奇怪的东西（为什么有＆＃34; ......＆＃34;？）：

/Users/Athos/Library/Developer/CoreSimulator/Devices/15855707-E728-4542-8DAA-3B71362D7DB6/data/Containers/Data/Applicati ... unny.mp4

但第二个是好的（我会手动检查文件是否在那里：

/Users/Athos/Library/Developer/CoreSimulator/Devices/15855707-E728-4542-8DAA-3B71362D7DB6/data/Containers/Data/Application/2ACD0002-1A1E-484C-B4E4-9486EBCFF74A/Documents/BuckBunny.mp4

你有什么线索吗？提前致谢

Answer 1

self.moviePlayer = [[MPMoviePlayerController alloc] init];
[self.moviePlayer setContentURL:[NSURL fileURLWithPath:[self.videos objectAtIndex:0]]];
// Use FileURLWithPath

Answer 2

试试这个：

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"%@/BuckBunny.mp4"];    
NSURL *movieURL = [NSURL fileURLWithPath:path];

self.moviePlayer = [[MPMoviePlayerController alloc] init];

if(movieURL!=nil){
    [self.moviePlayer setContentURL:movieURL];
    [self.moviePlayer.view setFrame:CGRectMake (0, 0, 320, 460)];
    [self.view addSubview:self.moviePlayer.view];
    [self.moviePlayer play];
}
