在播放声音时禁用UIButton

Question

this is my first simple app, i am using Xcode 5 iOS7.

My problem is when i press the button a sound is playing but if i press the button when the sound is playing the sound starting from the beginning. I don't know how to fix this, disable the button or if i can code something like this:

@implementation ViewController
AVAudioPlayer *audioPlayer;
BOOL playing;


if([audioPlayer isPlaying]){
  (playing = NO);
}

else if(playing == NO){
    [audioPlayer play];
    (playing = YES);
    }

but this doesn't work :)

Here is the code that i using now.

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController
AVAudioPlayer *audioPlayer;


- (void)viewDidLoad

{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

- (IBAction)playAudio:(id)sender {
NSURL *audioFile;
audioFile = [NSURL fileURLWithPath: [[NSBundle mainBundle] pathForResource:@"docka" ofType:@"mp3"]];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioFile error:nil];
[audioPlayer play];
}
@end

Thanks for any help!

You could call [yourButton setEnabled:NO]; in your IBAction to play the audio, then call [yourButton setEnabled:YES]; in the delegate method audioPlayerDidFinishPlaying:successfully: . First you'd have to set the delegate for your AVAudioPlayer, and adopt the protocol in your header file, but that should work.
