双UIAlertView

Question

我有两个UIAlertview，当我点击内部时，我想转到不同的页面，我创建两个xib文件，并在主视图控制器中导入它们，但是不知道为什么不能显示它们，当我检查~这里是我的代码时，这不是错误的标志：

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"LP01;" message:@"No Connection" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"Help", nil];


UIAlertView *alert1 = [[UIAlertView alloc] initWithTitle:@"LP01;" message:@"No Connection" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"Help", nil];




- (void)alert:(UIAlertView *)alertview clickedButtonAtIndex:(NSInteger)buttonIndex {


            if (buttonIndex == 1) {

        AViewController *switch1 = [[AViewController alloc]
                                   initWithNibName:nil bundle:nil];
        [self presentViewController:switch1 animated:YES completion:NULL];

            }
}

- (void)alert1:(UIAlertView *)alertview clickedButtonAtIndex:(NSInteger)buttonIndex {



    if (buttonIndex == 1) {


        BViewController *switch2 = [[BViewController alloc]
                                    initWithNibName:nil bundle:nil];
        [self presentViewController:switch2 animated:YES completion:NULL];

    }
}

请帮忙，谢谢~

Answer 1

UIAlertView *firstAlert = [[UIAlertView alloc] initWithTitle:@"LP01;" message:@"No Connection" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"Help", nil];


UIAlertView *secondAlert = [[UIAlertView alloc] initWithTitle:@"LP01;" message:@"No Connection" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"Help", nil];

//记住，对于与它相关的任何元素，代表方法都是相同的。因此，无论您有2、3或5 UIAlertView的you委托方法，只编写一次。

- (void)alert:(UIAlertView *)alertview clickedButtonAtIndex:(NSInteger)buttonIndex {
    if(alertview == firstAlert){



            AViewController *switch1 = [[AViewController alloc]
                                        initWithNibName:nil bundle:nil];
            [self presentViewController:switch1 animated:YES completion:NULL];


    }
    else if(alertview == secondAlert){



            BViewController *switch2 = [[BViewController alloc]
                                        initWithNibName:nil bundle:nil];
            [self presentViewController:switch2 animated:YES completion:NULL];


    }
}

//不要忘记调用firstAlert显示；或secondAlert显示；以显示您的警报
