Make AVAudioPlayer play a music file through phone

问题:

I want to play a music file through ear speaker,

What I am doing now is:

In viewDidLoad method ::::

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

Initializing music file in viewDidLoad ::::

musicFile = [NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"1985_Ring_" ofType:@"wav"]];                                                                        
click = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile  error:nil];

Now Playing file after routing audio in a method :::::

[[AVAudioSession sharedInstance] overrideOutputAudioPort:kAudioSessionOverrideAudioRoute_None error:nil];
[click2 play];

It's playing through loud speaker. Please guide me the proper way!

You need to change the category of AVAudioSession like this:

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord error:nil];

Find more details in Audio Session Programming Guide:

You can programmatically influence the audio output route. When using the AVAudioSessionCategoryPlayAndRecord category, audio normally goes to the receiver (the small speaker you hold to your ear when on a phone call).
