将UIViewController视图嵌入另一个UIViewController中 [英] Embedding UIViewController view inside another UIViewController

问题描述

在我的应用中，我有一个 login-register-forgotpasword 线框.该过程的每个步骤都在单独的 UIViewController 中实现，它们都在同一个 Storyboard 中，并且每个控制器之间的过渡都是动态的.到目前为止一切顺利.

In my app, I have a login-register-forgotpasword wireframe. Each step of the process is implemented in a separate UIViewController, all of them inside the same Storyboard, and transitions between each controller are animated. So far so good.

现在我们已经更改了设计，因此所有视图都具有相同的背景元素和标题(不完全是 UINavigationBar )，并且我不喜欢视图的动画效果看起来总是一样，只是表现出不同的形式.因此，我正在考虑采用不同的方法，而不是推送整个控制器，而只是显示/隐藏其视图，而是保留在同一控制器中.-

Now we've changed the design, so all views have the same background elements and a header (not exactly a UINavigationBar), and I don't like the feel of the animation to a view that always looks to be actually the same, but just showing a different form. So I'm considering different approaches to, instead of pushing whole controllers, just showing/hiding its views, but staying in the same controller.-

1)我的第一次尝试是实例化控制器要显示的视图，并将其添加到当前视图.像这样.-

1) My first try was instantiating the controller which view I want to show, and add it to the current view. Something like.-

- (IBAction)btnRegisterPressed:(id)sender {
    _viewHome.hidden = YES;    
    RegisterController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"registerNewUser"];
    [self.view addSubview:controller.view];
}

这是完美的，因为我为表单使用静态 UITableViews ，据我所知，每个表单都需要一个 UITableViewController .但是似乎 IBOutlets 和 IBActions 坏了.以某种方式可以实现这种方法吗?如果是这样，这被认为是不好的做法吗?

This one would be perfect, as I'm using static UITableViews for my forms, so as far as I know I'd need a UITableViewController for each one. But it seems IBOutlets and IBActions got broken. Is this approach possible in some way? If so, it's considered a bad practice?

2)我的第二个选择是在一个控制器中创建所有视图，并正确显示/隐藏它们.这将很难维护，而且我不得不忘记静态的 UITableViews .

2) My second option is just creating all the views inside one controller, and properly showing/hiding them. This would one be hard to maintain, and chances are I'd have to forget about static UITableViews.

有人能给我一些建议哪种选择更好的建议，或者向我指出我所缺少的任何其他可能的方法吗?

推荐答案

您的选项#1不适合编写，但接近您可能应该考虑的方法.您可以添加嵌套不同 UIViewController 的视图，但是这样做时，您应该使用

Your option #1 is not appropriate as written but close to an approach you should probably consider. You can add nest the views of different UIViewControllers however when you do so you should use the methods described in Managing Child View Controllers in a Custom Container so that the parent controller correctly manages its child controllers.
