本文展示了如何在iOS应用中使用UIAlertView和UIActionSheet创建弹出对话框及操作菜单。通过具体代码实例，详细介绍了如何设置标题、按钮文本，并实现点击事件处理。

@interface XXViewController : XXNavigationController <UIAlertViewDelegate> {}

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:_ContractCallNum message:nil delegate:self
                                          cancelButtonTitle:NSLocalizedString(@"Cancel", nil)
                                          otherButtonTitles:NSLocalizedString(@"Button 1", nil), NSLocalizedString(@"Button 2", nil), nil];

    [alert show];
    [alert release];

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    NSLog(@"alertView is %d", buttonIndex);


    switch (buttonIndex) {
        case 0:
            // Cancle
            break;
        case 1:
            {
            // Button 1
            }
            break;
        case 2:
            {
            // Button 2
            }
            break;

        default:
            break;
    }
}

        UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil
                                                                delegate:self
                                                        cancelButtonTitle:NSLocalizedString(@"Cancel",nil)
                                                   destructiveButtonTitle:nil
                                                        otherButtonTitles:NSLocalizedString(@"Button 1",nil),
                                    NSLocalizedString(@"Button 2",nil), nil];

        actionSheet.actionSheetStyle = UIActionSheetStyleDefault;
        [actionSheet showInView:[UIApplication sharedApplication].keyWindow];

- (void)actionSheet:(UIActionSheet *)actionSheet
clickedButtonAtIndex:(NSInteger)buttonIndex
{
    switch (buttonIndex)
    {
        case 0:
            {
            // Button 1
            }            break;
        case 1:
            {
            // Button 2
            }
            break;
        default:
            break;
    }
