[英]Present view controller in a container view at collection view didSelectItemAtIndexPath swift
I am trying to present a view controller in a container view when i select a cell from a collection view.当我从集合视图中选择一个单元格时,我试图在容器视图中显示一个视图控制器。 The problem is that I can't seem to understand how to present it in the container below the collection view.
问题是我似乎无法理解如何在集合视图下方的容器中呈现它。
I tried:我试过:
if (indexPath.row == 0){
// Presenting first view controller
let detailedViewController: ViewController =
self.storyboard!.instantiateViewControllerWithIdentifier("ViewController") as! ViewController
self.presentViewController(detailedViewController, animated: true, completion: nil)
How can I make it go to the container instead of presenting the whole view controller.我怎样才能让它进入容器而不是呈现整个视图控制器。 Thanks in advance!
提前致谢!
self.addChildViewController(detailedViewController)
containerView.addSubview(detailedViewController.view)
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()
}
