ios - AVAudioPlayer 不播放文件夹内的歌曲？

Question

我用这段代码来播放歌曲，它不是在文件夹或文件夹的文件夹中播放歌曲，除了 Documents 目录。

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];

Answer 1

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];
