这是 UIActionSheet 的实例。红色按钮称为“破坏性按钮”，黑色按钮称为“取消按钮”。

这是一个演示：

UIActionSheet *actSheet = [[UIActionSheet alloc] initWithTitle:@"The text to show on top. (Like the message about wiping the phone.)"delegate:nil cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Delete everything" otherButtonTitles:nil];
[actSheet ShowFromToolbar:self.toolbar];
[actSheet release];

That is an instance of a UIActionSheet. The red button is called the "destructive button" and the black button, the "cancel button".

Here is a demo:

UIActionSheet *actSheet = [[UIActionSheet alloc] initWithTitle:@"The text to show on top. (Like the message about wiping the phone.)"delegate:nil cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Delete everything" otherButtonTitles:nil];
[actSheet ShowFromToolbar:self.toolbar];
[actSheet release];

您需要使用 UIActionSheet。

您可以像这样创建一个 ActionSheet

UIActionSheet *actionSheet = [[UIActionSheet alloc] 
                                initWithTitle:@”YOUR_ACTION_SHEET_TITLE” 
                                delegate:self 
                                cancelButtonTitle:@”Cancel” 
                                destructiveButtonTitle:@”Erase Iphone” 
                                otherButtonTitles:nil];
[actionSheet showInView:self.view];
[actionSheet release];//If you are not using ARC

您需要实现 UIActionSheetDelegate 方法

- (void)actionSheet:(UIActionSheet *)actionSheet 
            clickedButtonAtIndex:(NSInteger)buttonIndex{

    if (buttonIndex == 0){
       //do your action
    }else if(buttonIndex == 1){
      // do your other action
    }
}

You need to use UIActionSheet.

You can create an ActionSheet like this

UIActionSheet *actionSheet = [[UIActionSheet alloc] 
                                initWithTitle:@”YOUR_ACTION_SHEET_TITLE” 
                                delegate:self 
                                cancelButtonTitle:@”Cancel” 
                                destructiveButtonTitle:@”Erase Iphone” 
                                otherButtonTitles:nil];
[actionSheet showInView:self.view];
[actionSheet release];//If you are not using ARC

You need to implement UIActionSheetDelegate method

- (void)actionSheet:(UIActionSheet *)actionSheet 
            clickedButtonAtIndex:(NSInteger)buttonIndex{

    if (buttonIndex == 0){
       //do your action
    }else if(buttonIndex == 1){
      // do your other action
    }
}
