清除緩衝的UIActionSheet，緩衝uiactionsheet

清除緩衝的UIActionSheet，緩衝uiactionsheet

 

點擊任何處，出現提示：

 

 

 

代碼:

 

//點擊任何處出現sheet

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

{

    UIActionSheet * sheet = [[UIActionSheet alloc] initWithTitle:@"確定要清空圖片緩衝？" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"確定" otherButtonTitles:nil, nil];

    [sheet showInView:self.view];

}

 

怎在iPhone中的UIActionSheet動態添加按鈕？

給你看看這段代碼：UIActionSheet *sheet = [[UIActionSheet alloc] init];[sheet addButtonWithTitle:@"Button 1"];if (useDestructiveButton) { [sheet setDestructiveButtonIndex:[sheet addButtonWithTitle:@"Button 2"]];}
 
怎更改變UIActionSheet的背景顏色

UIImageView *buttonbackgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"login_background"]];
[UIActionSheet addSubview:buttonbackgroundView];
想加什麼圖片或者換顏色，隨你便
