ios - 我使用 MPMoviePlayerController 播放存储在 ios6 文档的子文件夹中的视频，但它不起作用

Question

我播放存储在ios6 文档中名为test1MPMoviePlayerController的子文件夹中的视频，但它不起作用

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [paths objectAtIndex:0];//
NSString *movieFolderPath = [documentDirectory stringByAppendingPathComponent:@"/test1"];
NSString *newsrc = [[NSString alloc]initWithFormat:@"/%@",new.src ];
NSString *moviePath   = [movieFolderPath stringByAppendingPathComponent:newsrc];
NSURL *url = [[NSURL alloc]initWithString: [moviePath  stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding] ];
_moviePlayer = [[MPMoviePlayerController alloc]initWithContentURL:url];
_moviePlayer.movieSourceType = MPMovieSourceTypeFile;
_moviePlayer.view.frame = new.region;
[_moviePlayer prepareToPlay];
_moviePlayer.shouldAutoplay = YES;
[self.view addSubview:_moviePlayer.view];

好吧：url是/Users/fengsu/Library/Application Support/iPhone Simulator/6.0/Applications/53C97346-C8FD-42DF-AD37-F2B14D5D3984/Documents/test1/v1.mp4

我认为网址有问题，但我不知道为什么，请帮助我，非常感谢

Answer 1

问题是如何构造NSURL对象。

MPMoviePlayerController期望指向本地文件的 URL 有file://前缀。

方法如下：

NSString *filename = @"your_video.mpeg";
NSArray *pathArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);
NSString *documentsDirectory = [pathArray objectAtIndex:0];
NSString *yourVideoPath = [documentsDirectory stringByAppendingPathComponent:filename];
NSURL *movieURL = [NSURL fileURLWithPath:yourVideoPath isDirectory:NO];
_moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
// Rest of the code...

Answer 2

使用[NSURL fileURLWithPath:moviePath] That 用于从文件中打开 url。
