iOS中如何用UIAlertView来确认提交动作？

Question

原问题来自于CSDN问答频道，更多解决方案见：http://ask.csdn.net/questions/1519原问题描述：
大家好，请教一个关于UIGestureRecognizer的问题。
比如我需要在用户在操作之后，用UIAlertView来确认提交动作，我试过一些方法都没成功。解决方案：
这样：
UISwipeGestureRecognizer *gesture1 = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(didSwipeRight:)];
gesture1.direction = UISwipeGestureRecognizerDirectionRight;
[yourView addGestureRecognizer:gesture1];
在Action方法中：
-(void)didSwipeLeft:(UIGestureRecognizer *)gestureRecognizer {
    UIAlertView *Alert = [[UIAlertView alloc] initWithTitle:@"" message:@"Are you sure to commit with its action" delegate:self cancelButtonTitle:CKString(@"NO") otherButtonTitles:CKString(@"YES"),nil];
    [Alert show];
    Alert.tag=222;
    Alert.delegate=self;
    [Alert release];
}
在AlertView Delegate
-(void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {    if(alertView.tag==222) {
        if(buttonIndex==1)
        {
            //// Yes condition
        } else {
           ///// No condition
        }
    }
}ios

Answer 2

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"转账确认"
                                                        message:info
                                                       delegate:self
                                                    cancelButtonTitle:@"取消"
                                                    otherButtonTitles:@"确定", nil];
    alertView.tag = 1001;
    [alertView show];
    [alertView release];弹出框应该这样写，必须先设置它的tag再show出来，才管用弹出框的委托方法
