I tried to play mp3 file using AVP player. But i couldn't play it..my code is
NSString *fileurl=[FILE_URL_Array objectAtIndex:indexPath.row];
NSArray *parts = [fileurl componentsSeparatedByString:#"/"];
NSString *filename = [parts lastObject];
NSLog(#"file name is %#",filename);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,filename];
//NSString* documentsPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];
NSString* foofile = [documentsDirectory stringByAppendingPathComponent:filename];
NSLog(#"foofile %#",foofile);
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:foofile];
NSLog(#"boolean value is %hhd",fileExists);
if (fileExists)
{
NSURL *audioURL = [NSURL fileURLWithPath:filePath];
NSLog(#"existig url is%#",audioURL);
NSData *urlData =[NSData dataWithContentsOfURL:audioURL];
// NSString *sourcePath =[audioURL path];
//UISaveVideoAtPathToSavedPhotosAlbum(sourcePath,nil,nil,nil);
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,filename];
[urlData writeToFile:filePath atomically:YES];

audioPlayer.delegate = self;
[audioPlayer play];
}
but i am unable to play that audio file....Please give your valuable solution.Thanks in advance...

Answer 1

You're currently appending documentsDirectory twice.
NSString *filePath = [NSString stringWithFormat:#"%#/%#", documentsDirectory,filename];
//NSString* documentsPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];
NSString* foofile = [documentsDirectory stringByAppendingPathComponent:filename];
Once in filePath, and again in foofile.
Additionally, you seem to be doing a whole bunch of extra processing that you don't need to be doing. You should be able to create the audio player from the initial file url:
NSString *fileurl=[FILE_URL_Array objectAtIndex:indexPath.row];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL urlWithString:fileUrl] error:&error];
if (error != nil) {
NSLog(#"Error creating player: %#", error);
}
audioPlayer.delegate = self;
[audioPlayer prepareToPlay];
[audioPlayer play];
