ios - 无法以编程方式导航到另一个 UIViewController iOS

Question

我正在尝试导航到“主页” View Controller ，为此我在 ContainerViewController 中编写了以下代码。但是一旦代码执行，应用程序就会挂起并显示 100% 的 CPU 使用率。请帮忙。

- (IBAction) home:(UIButton *)sender

{

    HomeViewController *homeViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"HomeViewController"];

    [self.navigationController pushViewController:homeViewController animated:YES];

    //[self presentViewController:homeViewController animated:YES completion:nil];

}

Answer 1

我有一个问题想问你

1-如果您想将 SecondViewController 推送到 FirstViewController，那么您的代码就足够了

2-如果你在firstViewController中有一个containerview，你想把SecondViewcontroller的view添加到firstViewController

然后使用这段代码

UIViewController*vc1 = [[test1 alloc]initWithNibName:@"SecondViewController" bundle:nil];

//add to the container vc which is self    
[self addChildViewController:vc1];

//the entry view (will be removed from it superview later by the api)
[self.view addSubview:vc1.view];
