UIAlertView 中的 UIActionSheet

问题描述

我试图在用户触摸 UIAlertView 中的按钮时显示 UIActionSheet:

I'm trying to show a UIActionSheet when the user touches a button in a UIAlertView:

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (buttonIndex == 0)
    {
        UIActionSheet *actionSheet = ...
        [actionSheet showFromTabBar:self.tabBarController.tabBar];
    }
}

当操作表显示时，警报视图仍在操作表后面的屏幕上，当我触摸操作表中的按钮时 - 操作表消失但整个屏幕变暗，警报视图仍然打开，并且我无法拒绝它.

When the action sheet is shown the alert view is still on the screen behind the action sheet, and when I touch a button in the action sheet - the action sheet disappears but the whole screen is dimmed with the alert view still on and I can't dismiss it.

我尝试了几种方法，例如在短暂延迟后显示操作表或以编程方式关闭警报视图，但没有任何效果.在最好的情况下(以编程方式关闭警报视图)，警报视图确实在发生某种奇怪的转换后消失了，但我在日志中收到了等待栅栏未能收到回复"错误.

I tried several things, such as showing the action sheet after a short delay or dismissing the alert view programmatically, but nothing worked. In the best case (dismissing the alert view programmatically) the alert view did disappear after a somewhat-strange transition but I got a "wait-fence failed to receive reply" error in the log when it did.

如何从警报视图以有序的方式显示操作表?

How can I show an action sheet from an alert view in an orderly manner?

推荐答案

在这种情况下，你应该使用

In this case, you should use

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex

方法而不是，

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

所以你的代码将是:

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    if (buttonIndex == 0)
    {
        UIActionSheet *actionSheet = ...
        [actionSheet showFromTabBar:self.tabBarController.tabBar];
    }
}

谢谢，
