Playing sound on a button click - iphone

Question

I'm facing a very strange issue, my requirement is to play a sound on the button click and this is my code:
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *path=[[NSBundle mainBundle] pathForResource:#"button-3" ofType:#"mp3"];
tapSound=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]];
[tapSound prepareToPlay];
tapSound.delegate=self;
//creating the button in view did load and button is declared in .h
btn=[UIButton buttonWithType:UIButtonTypeCustom];
btn.frame=CGRectMake(x, y, 58,58);
[btn addTarget:self action:#selector(btnClkd:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
}
//click method
-(void)btnClkd:(UIButton*)sender
{
[tapSound play];
}
But when I run the code and click the button my app gets crashed and got this error: "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIButton play]: unrecognized selector sent to instance 0x758c790' "
But if I play the sound anywhere else but not on the click of the button then it get played without any issue.I dont know why this is happening? Please help me

Answer 1

Do this:
-(void)btnClkd:(UIButton*)sender
{
NSString *path=[[NSBundle mainBundle] pathForResource:#"button-3" ofType:#"mp3"];
tapSound = nil;
tapSound=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]];
[tapSound prepareToPlay];
tapSound.delegate=self;
[tapSound play];
}

Try this one . Add in your .h file
.h file
#import <AVFoundation/AVFoundation.h>
#import <AudioUnit/AudioUnit.h>
AVAudioPlayer *player1;
#property(nonatomic ,retain)AVAudioPlayer *player1;
in your .m file
#synthesize player1;
- (void)viewDidLoad
{
[super viewDidLoad];
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"button-3" ofType:#"mp3"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:soundFilePath];
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil];
[fileURL release];
self.player1 = audioPlayer;
[audioPlayer release];
[self.player1 prepareToPlay];
[self.player1 setDelegate:self];
[pool release];
//creating the button in view did load and button is declared in .h
btn=[UIButton buttonWithType:UIButtonTypeCustom];
btn.frame=CGRectMake(x, y, 58,58);
[btn addTarget:self action:#selector(btnClkd:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn];
}
-(void)btnClkd:(UIButton*)sender {
[self.player1 play];
}
