UIImageView* imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0, 300.0, 43.0, 43.0)]; 
    [imageView setBackgroundColor:[UIColor clearColor]]; 
    [imageView setImage:[UIImage imageNamed:@"test.png"]]; 
    [self.view addSubview:imageView]; 

[UIView setAnimationRepeatAutoreverses:YES]; 
[UIView setAnimationBeginsFromCurrentState:YES]; 
[UIView animateWithDuration: 0.2f 
        delay: 0.0f 
        options: UIViewAnimationOptionRepeat | UIViewAnimationOptionAutoreverse | UIViewAnimationOptionBeginFromCurrentState 
       animations: ^(void){[imageView setFrame:CGRectMake(0.0, 350.0, 43.0, 43.0)];} 
       completion: nil]; 


UIButton* button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

嗨，你有什麼問題。你能解釋清楚 – Satya

我將上面的代碼添加到viewController，運行時，該按鈕不能被觸摸 – HunkSmile

應用程序崩潰，而觸摸按鈕？你根本看不到按鈕？ – EmptyStack

嘗試修改您的animateWithDuration：見下文

[UIView animateWithDuration: 0.2f 
         delay: 0.0f 
         options: UIViewAnimationOptionAllowUserInteraction | UIViewAnimationOptionRepeat | UIViewAnimationOptionAutoreverse | UIViewAnimationOptionBeginFromCurrentState 
        animations: ^(void){[imageView setFrame:CGRectMake(0.0, 350.0, 43.0, 43.0)];} 
        completion: nil];

在我的附加值UIViewAnimationOptionAllowUserInteraction

謝謝。你是對的 – HunkSmile

做如下改變按鈕定義：

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

你的方法應該是象下面這樣：

-(IBAction)buttonHandle:(id)sender 
{ 
}

我希望這將是有益的。

add UIViewAnimationOptionAllowUserInteraction – HunkSmile

的選項屬性。如果你不能夠觸摸按鈕（如果點擊不工作），然後

編寫代碼

[self.view bringSubviewToFront:button];

在方法結束時。

感謝您的回答 – HunkSmile

我想你想對按鈕執行操作，所以試試這段代碼。

 UIButton* button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 
     [button setFrame:CGRectMake(100, 0, 100, 30)]; 
     [button setTitle:@"Button" forState:UIControlStateNormal]; 
    [button addTarget:self   action:@selector(buttonPressed:)forControlEvents:UIControlEventTouchUpInside]; 

     [self.view addSubview:button]; 

-(IBAction)buttonPressed:(id)sender 
{ 
    //put code here you want to perform action on button 
}
