我有一个视频文件保存在我的应用程序的文档文件夹中的本地目录中。我想在用户点击我创建的嵌入式表格视图中的项目时播放该文件。我播放视频的代码如下:
NSString* documentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString* path = [documentPath stringByAppendingPathComponent:@"DemoRecording.mp4"];
NSURL* movieURL = [NSURL fileURLWithPath: path];
[player.view setFrame: self.view.bounds];
[self.view addSubView: player.view];
[player play];
MPMoviePlayerViewController* moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL: movieURL];
[self presentMoviePlayerViewControllerAnimated: moviePlayer];
视频无法播放。路径正确,文件存在。
我知道这是一个重复的问题。我已经提到了这些链接:
Playing a Downloaded Video from the Documents Directory with Cocoa-Touch
MPMoviePlayer load and play movie saved in app documents
但无法找到明确的答案。
请帮我解决这个问题。我正在使用iOS 5.1.1,如果这改变了什么。
编辑:
确实有效。我忘了将URL传递给电影播放器。

您可以像这样从文档目录播放视频: -
-(IBAction)playVideo
{
NSURL *vedioURL;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSArray *filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory error:nil];
NSLog(@"files array %@", filePathsArray);
NSString *fullpath;
for ( NSString *apath in filePathsArray )
{
fullpath = [documentsDirectory stringByAppendingPathComponent:apath];
vedioURL =[NSURL fileURLWithPath:fullpath];
}
NSLog(@"vurl %@",vedioURL);
MPMoviePlayerViewController *videoPlayerView = [[MPMoviePlayerViewController alloc] initWithContentURL:vedioURL];
[self presentMoviePlayerViewControllerAnimated:videoPlayerView];
[videoPlayerView.moviePlayer play];
}
注意
请注意,请勿忘记包含请求的Framework或连接Delegate

你的错误是你在DemoRecording.mp4之前错过了/
应该是
NSString* path = [documentPath stringByAppendingPathComponent:@"/DemoRecording.mp4"];
此外,您在声明之前编写player
语句。
