IOS:关闭两个viewController

Question

我有三个viewController

第一、第二、第三

从二开到三开我用

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

现在我想从第三名回到第一名；然后我在第二个代码中设置 viewDidAppear:

[self dismissModalViewControllerAnimated:NO];

但是有 1 秒我看到了 Second，我不想看...我该怎么办？

Answer 1

您需要先关闭第三个 View Controller ，然后再关闭第二个 View Controller 。当您想首先访问 View Controller 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];
 }
