IOS:关闭两个viewController

Question

我有三个viewController

第一,第二和第三

从第二到第三我用

Third *third = [[Third alloc]initWithNibName:@"Third" bundle:nil];
[self presentModalViewController:third animated:YES];
[third release];

现在我想从第三到第一回来; 然后我在第二个代码中设置viewDidAppear:

[self dismissModalViewControllerAnimated:NO];

但是1秒钟我看到第二个,我不想看它......我该怎么办？

Answer 1

您需要首先关闭第三个视图控制器,然后关闭第二个Viewcontroller.当您想要第一个视图控制器时,请执行以下代码.

-(void)goToFirstView{
        UIViewController *vc = [self parentViewController];
   //     UIViewController *vc = [self presentingViewController]; //ios 5 or later
        [self dismissModalViewControllerAnimated:NO];
        [vc dismissModalViewControllerAnimated:YES];
 }

Answer 2

首先如何消除第三模式视图？也许是通过用户触摸“完成”按钮？如果是这样，则您想在按钮的处理程序中同时关闭这两个按钮。

您可以将两者都视为：

[self dismissModalViewControllerAnimated: YES];
[self.presentingViewController dismissModalViewControllerAnimated: NO];
