确认UIGestureRecognizer

Question

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。

清高手帮忙解决一下，谢谢。

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
        }
    }
}
