iOS - 動畫UIButton ImageView圖像導致按鈕被選中後

Question

我想動畫的圖像UIButton。動畫運行正常，但之後它總是在按鈕上放上灰色色調（，好像它是突出顯示/選中）。

代碼：

NSArray *images = [[NSArray alloc] init]; 
images = [NSArray arrayWithObjects: 
      [UIImage imageNamed:IMAGE1], 
      [UIImage imageNamed:IMAGE2], 
      [UIImage imageNamed:IMAGE3], 
      [UIImage imageNamed:IMAGE4], 
      nil]; 
iconBobble.imageView.animationImages = images; 
iconBobble.imageView.animationDuration = 1.5; 
iconBobble.imageView.animationRepeatCount = 1; 
[iconBobble.imageView startAnimating];

adjustsImageWhenHighlighted屬性將解決您的問題。

此代碼將解決你的問題....

-(IBAction)animateButton:(id)sender 
{ 
    [iconBobble setAdjustsImageWhenHighlighted:NO]; 

    NSArray *images = [[NSArray alloc] init]; 
    images = [NSArray arrayWithObjects: 
       [UIImage imageNamed:IMAGE1], 
       [UIImage imageNamed:IMAGE2], 
       [UIImage imageNamed:IMAGE3], 
       [UIImage imageNamed:IMAGE4], 
       nil]; 

    float animationDuration = 1.5; 
    iconBobble.imageView.animationImages = images; 
    iconBobble.imageView.animationDuration = animationDuration; 
    iconBobble.imageView.animationRepeatCount = 1; 
    [iconBobble.imageView startAnimating]; 
    [self performSelector:@selector(stopButtonAnimation) withObject:nil afterDelay:animationDuration]; 
} 
-(void)stopButtonAnimation 
{ 
    [iconBobble.imageView stopAnimating]; 
} 

這是工作正常，我:-)
