AVAudioPlayer不播放文件夹内的歌曲？

我用这个代码来播放歌曲，它不是播放除了文档目录以外的文件夹或文件夹内的歌曲。

NSString *songname=[NSString stringWithFormat:@"%@",songArray[songIndex]]; NSLog(@"songname:%@",songname); NSString* saveFileName = songname; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:saveFileName]; NSURL *url = [[NSURL alloc] initFileURLWithPath: path]; self.audioPlayer=[[AVAudioPlayer alloc] initWithContentsOfURL:url error:NULL];

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"github.mp4"]; NSURL *url1 = [[NSURL alloc] initFileURLWithPath: path]; avPlayer = [AVPlayer playerWithURL:url1] ; [self.avplayer play];
