Loading a ViewController inside a Container View
提问by Godfather
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:
我在 VC 中有一个全屏的 containerView。如果我从 Storyboard 手动将一个孩子添加到 containerView 做一个嵌入 segue 看起来很好：
But if I embed the VC by code:
但是如果我通过代码嵌入 VC：
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)
}
}
I get super strange results:
我得到了超级奇怪的结果：

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:
你需要告诉你的 BannerContainer 视图控制器它有一个新的子控制器，并告诉子它有一个父 VC。这在此处的 Apple 文档中有所描述。像这样：
[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];
Or in Swift:
或者在 Swift 中：
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)
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.
这确保了将各种布局和触摸方法传递给子 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造成的。

Tried to use the answer above but it turns out CGRectMakeisn't available anymore.
尝试使用上面的答案，但结果CGRectMake不再可用。
Updated for Swift 3:
为 Swift 3 更新：
self.addChildViewController(vc)
vc.view.frame = CGRect(x: 0, y: 0, width: self.container.frame.size.width, height: self.container.frame.size.height)
self.container.addSubview(vc.view)
vc.didMoveToParentViewController(self)

Update for Swift 4.2/5.
Swift 4.2/5 的更新。
let listVc = ListViewController()
listVc.view.frame = CGRect(x: 0, y: 0, width: self.listView.frame.width, height: self.listView.frame.height)
addChild(listVc)
listVc.didMove(toParent: self)
ListViewController is another view controller to be embedded.
ListViewController 是另一个要嵌入的视图控制器。

Just call this function: -
只需调用此函数：-
private func addChildView(viewController: UIViewController, in view: UIView) {
viewController.view.autoresizingMask = [.flexibleHeight, .flexibleWidth]
viewController.view.frame = view.bounds
addChild(viewController)
view.addSubview(viewController.view)
viewController.didMove(toParent: self)
}

Swift 5.0 Use this functions to add and remove child VC:
Swift 5.0 使用此函数添加和删除子 VC：
private func add(asChildViewController viewController: UIViewController, childFrame:CGRect) {
// Add Child View Controller
addChild(viewController)
// Add Child View as Subview
view.addSubview(viewController.view)
// Configure Child View
viewController.view.frame = childFrame
viewController.view.autoresizingMask = [.flexibleWidth, .flexibleHeight]
// Notify Child View Controller
viewController.didMove(toParent: self)
}
private func remove(asChildViewController viewController: UIViewController) {
// Notify Child View Controller
viewController.willMove(toParent: nil)
// Remove Child View From Superview
viewController.view.removeFromSuperview()
// Notify Child View Controller
viewController.removeFromParent()
}
