ios - AVAudioPlayer フォルダ内の曲を再生しませんか?

Question

このコードを使用して曲を再生しましたが、Documents ディレクトリ以外のフォルダーまたはフォルダーのフォルダー内の曲は再生されません。

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];
