Question

我有一个家庭视图，当点击它再次进入另一个视图时我将转到另一个视图。当点击该视图上的按钮时，将出现模态视图，然后在点击每个视图时再显示3个模态视图modalview。当点击最终的模态视图时，会出现一个警告，当点击该警报我想要显示根主视图。是否可能？

Answer 1

使用给定的代码段显示AlertView：

UIAlertView * alert = [[UIAlertView alloc] initWithTitle：标题消息：@“Alert Message” delegate：self cancelButtonTitle：@“Ok”otherButtonTitles：nil]; [警示显示]; [警告发布];

委托方法实施：

（void）alertView：（UIAlertView *）alertView clickedButtonAtIndex：（NSInteger）buttonIndex { [self.navigationController popToRootViewControllerAnimated：YES];

}

Answer 2

以下给出的示例代码：

UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:@"Alert Message?" message:@"Error......" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK"] autorelease];
[alert show];

实现警报View的委托函数如下所示

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (buttonIndex == 0)
    {
        //cancel clicked ...do your action
    }
    else if (buttonIndex == 1)
    {
        //OK clicked
         [self.navigationController popToViewController animated:YES];
    }
}

Answer 3

int c=[self.navigationController.viewControllers count]-4;
            [self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:c] animated:YES];

Answer 4

只需在.h文件中给代表，然后在alertview的委托方法中写下波纹管代码..

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    if (buttonIndex == 1) {
            [self.navigationController popToRootViewControllerAnimated:YES];///this line is important..
    }
    else{
      // do your action...
     }
}

我希望这个答案对你有用..
