如何通過動畫在視圖中隱藏內容

我正在顯示一個視圖，其上有一個按鈕。單擊此按鈕時，我將通過Objective C中定義的動畫方法顯示PopUp視圖，並通過彈出視圖添加圖像然後在任何點擊視圖時，這個彈出視圖隱藏，將其寬度和高度設置爲零，但其上的圖像不隱藏。可以隱藏它嗎？？這些方法我用..作出輕敲觸摸的觀點後如何通過動畫在視圖中隱藏內容

這種方法點擊按鈕後，叫..

-(void)btnImageClkForPopUp:(id)sender 
{ 
[UIView beginAnimations:nil context:nil]; 
[UIView setAnimationDuration:2.5]; 
popup_viewforimage.frame=CGRectMake(8, 30, 300, 250); 
popup_viewforimage.backgroundColor=[UIColor whiteColor]; 

UIImageView *imgview=[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 300, 250)]; 
imgview.image=[UIImage imageNamed:@"apple.jpeg"]; 
[popup_viewforimage addSubview:imgview]; 

[self.view addSubview:popup_viewforimage]; 
[UIView commitAnimations]; 
}

這兩種方法稱爲隱藏這個

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch 
{ 
if ([touch.view isKindOfClass:[UIButton class]]) 
{ 
return NO; 
} 
return YES; 
} 

-(void)hidekeyboard 
{ 
[UIView beginAnimations:nil context:nil]; 
[UIView setAnimationDuration:2.5]; 
popup_viewforimage.frame= CGRectMake(15, 65, 0, 0); 
popup_viewforimage.backgroundColor=[UIColor grayColor]; 
[self.view addSubview:popup_viewforimage]; 
    [UIView commitAnimations]; 
}
