我想加载没有按钮的视图控制器.我将标识符设置为 10 并尝试使用

I want to load view controller without button. I set the identifier to 10 and tried to use

if(...){ 
    //load ViewController2
    [[self storyboard] instantiateViewControllerWithIdentifier:@"10"];
}

但什么也没发生.

有了这个功能，它s 不也不起作用

 UIViewController *vc = [[self storyboard] instantiateViewControllerWithIdentifier:@"10"];

[self.navigationController pushViewController:vc];

有什么问题吗?

推荐答案

调用 instantiateViewControllerWithIdentifier: 将实例化一个视图控制器，正如它所说的.而已.如果您想实际显示它，您必须使用一个变量并将其推送到您的视图控制器堆栈.

Calling instantiateViewControllerWithIdentifier: will instantiate a view controller, as it says. Nothing more. If you want to actually show it you have to use a variable and push it to your view controller stack.

UIViewController *vc = [[self storyboard] instantiateViewControllerWithIdentifier:@"10"];
[self.navigationController pushViewController:vc];

当然，您必须使用 UINavigationController 来做到这一点.

Of course you have to be using a UINavigationController to do this.
