按音量按鈕時更改音量滑塊位置

Question

如何將音量按鈕與我的音量滑塊連接？

我使用AVAudioPlayer和滑塊音量和物理音量按鈕工作正常，但事情是，他們正在單獨工作，所以我需要實現的是，當我按音量滑塊物理音量按鈕也改變位置。

我的代碼是按照下文：

-(IBAction)btnClked:(id)sender { 

    NSURL *musicFile; 

    musicFile = [NSURL fileURLWithPath:[[NSBundle mainBundle] 
             pathForResource:@"music" 
             ofType:@"mp3"]]; 

    myAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil]; 

    [self.button setBackgroundImage:[UIImage imageNamed:@"Play.png"] forState:UIControlStateNormal]; 

    if (self.button.tag == 0) { 
     self.button.tag = 1; 
     [self.button setImage:[UIImage imageNamed:@"Stop.png"] forState:UIControlStateNormal]; 

     [myAudio play]; 
     myAudio.numberOfLoops = -1; 
     myAudio.currentTime = 0; 
     myAudio.volume = 0.5; 

    } else { 
     self.button.tag = 0; 
     [self.button setImage:[UIImage imageNamed:@"Play.png"] forState:UIControlStateNormal]; 
     [myAudio stop]; 

    } 
} 

我的滑塊調整方法如下：提前

- (IBAction)sliderChange:(UISlider *)sender { 
    myAudio.volume = sender.value/1; 
} 

謝謝！

使用這種MPVolumeView設置音量滑塊ü可以自定義你的方式......

- (void)showTheVolumeSlider :(UIView *)viewVolumeParent{ 

    MPVolumeView *volumeView = [[MPVolumeView alloc] initWithFrame:viewVolumeParent.bounds] ; 
    volumeView.showsRouteButton = NO; 
    [viewVolumeParent addSubview:volumeView]; 
// [volumeView setVolumeThumbImage:[UIImage imageNamed:@"thumb.png"] forState:UIControlStateNormal]; 

    [[volumeView subviews] enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) { 
     if ([obj isKindOfClass:[UISlider class]]) { 

      [obj setThumbImage:[UIImage imageNamed:@"thumb.png"]forState:UIControlStateNormal]; 
      *stop = YES; 
     } 
    }]; 
}
