在容器视图中加载 ViewController

问题描述

我在 VC 中有一个全屏的 containerView.如果我从 Storyboard 手动将子项添加到 containerView 中，则进行嵌入 segue 看起来很好:

I have a containerView with full screen inside a VC. If i add a child to the containerView manually from a Storyboard doing a embed segue looks fine:

但如果我通过代码嵌入 VC:

But if I embed the VC by code:

class BannerContainerVC: UIViewController {

    @IBOutlet weak var container: UIView!

    override func viewDidLoad() {
        super.viewDidLoad()
        let vc = storyboard?.instantiateViewControllerWithIdentifier("test") as UIViewController
        self.container.addSubview(vc.view)
    }
}

我得到了超级奇怪的结果:

I get super strange results:

推荐答案

你需要告诉你的 BannerContainer 视图控制器它有一个新的子控制器，并告诉 Child 它有一个父 VC.Apple Docs 此处对此进行了描述.像这样:

You need to tell your BannerContainer view controller that it has a new child controller, and to tell the Child that it has a parent VC. This is described in the Apple Docs here. Like this:

   [self addChildViewController:vc];
   vc.view.frame = CGRectMake(0, 0, self.container.frame.size.width, self.container.frame.size.height);
   [self.container addSubview:vc.view];
   [vc didMoveToParentViewController:self];

或者在 Swift 中:

Or in Swift:

    self.addChildViewController(vc)
    vc.view.frame = CGRectMake(0, 0, self.container.frame.size.width, self.container.frame.size.height);
    self.container.addSubview(vc.view)
    vc.didMoveToParentViewController(self)

这样可以保证各种布局和触摸方法都传递给子VC；我怀疑您遇到的布局问题可能是由于当前未调用这些方法.

This ensures that various layout and touch methods are passed through to the child VC; I suspect the layout problems you have may be due to those methods not currently being called.
