将UIViewController视图嵌入另一个UIViewController中

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?
