單擊其他UIButton時更改UIButton的UIImage

當用戶單擊UIButton1(rewind button)時，需要更改其他UIButton2(playbutton)的UIImage。我怎樣才能做到這一點。單擊其他UIButton時更改UIButton的UIImage

UIButton *rewindButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
[rewindButton addTarget:self action:@selector(rewind:) forControlEvents:UIControlEventTouchUpInside]; 
rewindButton.frame = CGRectMake(0, 0, 38, 38); 
UIImage *imge = [UIImage imageNamed:@"Rewind Icon .png"]; 
[rewindButton setImage:imge forState:UIControlStateNormal]; 
UIBarButtonItem *rewind = [[UIBarButtonItem alloc] initWithCustomView:rewindButton]; 

-(void)rewind:(id)sender{ 
audioPlayer.currentTime = 0; 
[timer invalidate]; 
ContainerViewController *viewController = [[[ContainerViewController alloc] init]autorelease]; 
viewController.view.frame = CGRectMake(0, 0, 320, 480); 
[self.view addSubview:viewController.view]; 
[self.view addSubview:toolbar]; 
self.timer = [NSTimer scheduledTimerWithTimeInterval:11.0 
            target:self 
            selector:@selector(displayviewsAction:) 
            userInfo:nil 
            repeats:NO]; 
} 

//Add Play Button 

_playButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
[_playButton addTarget:self action:@selector(playpauseAction:) forControlEvents:UIControlEventTouchUpInside]; 
_playButton.frame = CGRectMake(0, 0, 38, 38); 
[_playButton setImage:[UIImage imageNamed:@"Play Icon.png"] forState:UIControlStateNormal]; 
[_playButton setImage:[UIImage imageNamed:@"52.png"] forState:UIControlStateSelected]; 
UIBarButtonItem *play = [[UIBarButtonItem alloc] initWithCustomView:self.playButton]; 


-(void)playpauseAction:(id)sender { 
if([audioPlayer isPlaying]) 
{ 
    [sender setImage:[UIImage imageNamed:@"Play Icon.png"] forState:UIControlStateSelected]; 
    [audioPlayer pause]; 
    [self pauseTimer]; 
    [self pauseLayer:self.view.layer]; 

}else{ 
    [sender setImage:[UIImage imageNamed:@"pause icon.png"] forState:UIControlStateNormal]; 
    [audioPlayer play]; 
    [self resumeTimer]; 
    [self resumeLayer:self.view.layer]; 
    if(isFirstTime == YES) 
    { 
     self.timer = [NSTimer scheduledTimerWithTimeInterval:11.0 
              target:self 
              selector:@selector(displayviewsAction:) 
              userInfo:nil 
              repeats:NO]; 
     isFirstTime = NO; 
    } 
    } 
    }

當用戶點擊UIButton1(rewind button)要求是其他UIButton2(play button)的UIImage從遊戲中的icon.png到pauseicon.png改變。

我該怎麼做。

任何想法。

是否直接設置按鈕的圖像不起作用？

-(void)rewind:(id)sender{ 
    [_playButton setImage:[UIImage imageNamed:@"pause icon.png"] forState:UIControlStateNormal]; 
    //... 
}

我該如何讓播放按鈕執行以下步驟[audioPlayer play]; [self resumeTimer]; [self resumeLayer：self.view.layer];當倒帶按鈕改變播放按鈕的UIImage [_playButton setImage：[UIImage imageNamed：@「pause icon.png」] forState：UIControlStateNormal];這意味着當倒帶按鈕將播放按鈕的圖像更改爲暫停時，並且當用戶嘗試暫停播放按鈕時以及用戶恢復播放按鈕時，播放按鈕應執行以下步驟[audioPlayer play]; [self resumeTimer]; [self resumeLayer：self.view.layer]; – user1452248 2012-07-11 17:47:14

_playButton已經連接到執行這些步驟的playpauseAction：方法。您可以嘗試 - （void）倒帶：{[audioPlayer pause];而不是僅在回放中設置播放按鈕圖像。 audioPlayer.currentTime = 0; [self playpauseAction：_playButton]; // ...} – thelaws 2012-07-11 18:07:58
