Question

i have created two UIButtons and only play button is appearing on the UIToolbar. In the play method i want is when play button is pressed it shows pause button and if user presses pause button it pauses the audiofile and then shows the play button.

UIButton *playButton = [UIButton buttonWithType:UIButtonTypeCustom];

[playButton addTarget:self action:@selector(play:) forControlEvents:UIControlEventTouchUpInside];

playButton.frame = CGRectMake(0, 0, 50, 50);

UIImage *image = [UIImage imageNamed:@"play.png"];

[playButton setImage:image forState:UIControlStateNormal];

UIBarButtonItem *play = [[UIBarButtonItem alloc] initWithCustomView:playButton];



UIButton *pauseButton = [UIButton buttonWithType:UIButtonTypeCustom];

 [pauseButton addTarget:self action:@selector(pause:) forControlEvents:UIControlEventTouchUpInside];

pauseButton.frame = CGRectMake(0, 0, 50, 50);

UIImage *imge = [UIImage imageNamed:@"pause.png"];

[pauseButton setImage:imge forState:UIControlStateNormal];

-(void)play:(id)sender 
{

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"theme" 
                                                     ofType:@"mp3"];

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

audioPlayer = [[AVAudioPlayer alloc] 
              initWithContentsOfURL:fileURL error:nil];

audioPlayer.currentTime = 0;

[audioPlayer play];

[fileURL release];  

}

I need help in implementing this

In the play method

i did

[audioPlayer play];

UIImage *imge = [UIImage imageNamed:@"pause.png"];

[pauseButton setImage:imge forState:UIControlStateNormal];

[audioPlayer pause];

UIImage *image = [UIImage imageNamed:@"play.png"];

[playButton setImage:image forState:UIControlStateNormal];

[audioPlayer Play];

I think i m doing wrong way

Please advice .

Thanks for help.

Thanks

Use only one button with 1 image for each state (Selected and Normal):

UIButton *mediaButton = [UIButton buttonWithType:UIButtonTypeCustom];
mediaButton.frame = CGRectMake(0, 0, 50, 50);

[mediaButton setImage:[UIImage imageNamed:@"play.png"] forState:UIControlStateNormal];
[mediaButton setImage:[UIImage imageNamed:@"pause.png"] forState:UIControlStateSelected];

[playButton addTarget:self action:@selector(mediaAction:) forControlEvents:UIControlEventTouchUpInside];

-(void)mediaAction:(UIButton *)sender 
{
   if(sender.selected){
    // pause action
   } else {
    // play action
   }

    sender.selected = !sender.selected;
}
