提示的简易写法

1.提示的声明方法

 

UIAlertView *alert = [[UIAlertViewalloc] initWithTitle:@"提示"

                                                    message:@"您还没有支付哦，返回将取消订单，确认返回？"

                                                   delegate:nil

                                          cancelButtonTitle:@"返回"

                                          otherButtonTitles:@"继续支付", nil];

alert.tag = 1002;

alert.delegate = self;

[alert show];

 

 

2.代理写法：

 

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

{

    if (alertView.tag == 1001) {

        return;

    }

   

    if (buttonIndex == 1) {

        return;

    }

    else {

        [supergoBack];

    }

}
