Question

I am using AVFoundation to play wav files. But i could not make it play. Also no errors or warnings showed up.

XCode is 4.2 and device is iOS 5.

- (IBAction) playSelectedAlarm:(id)sender {

UIButton *button = (UIButton *)sender;

int bTag = button.tag;

NSString *fileName = [NSString stringWithFormat:@"%d23333", bTag];

NSLog(@"%@", fileName);

NSString *path = [[NSBundle mainBundle] pathForResource:fileName ofType:@"wav"];

NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: path];

AVAudioPlayer *theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:NULL];

theAudio.volume = 1.0;

theAudio.delegate = self;

[theAudio prepareToPlay];

[theAudio play];

}

Answer 1

Here is the solution;

I set AVAudioPlayer in header file..

@property (nonatomic, retain) AVAudioPlayer *theAudio;

i guess ‘retain’ is solved my problem. Because after i sending “play”, it sends “release” to balance the alloc. When AVAudioPlayer is deallocated it stops playing audio.
