[英]swift Dismiss ViewController from a helper / another class
I have a problem when i try to dismiss a view from a function of a helperClass instanced in the viewer class 我尝试从查看器类中实例化的helperClass的功能中消除视图时遇到问题
public func set(playerController: AVPlayerViewController){
playerController?.dismiss(animated: true, completion: nil)
whose view is not in the window hierarchy!
其视图不在窗口层次结构中!
how can I pass correctly the controller so the helper class can dismiss it? 如何正确传递控制器,以便助手类可以将其关闭?
Viewerclass: 查看者类别:
helper.add(player: player)
helper.set(playerController: playerController)
You should be able to just do dismiss(animated: true, completion: nil)
from the presented view controller, as Apple libraries handle the dismissal both from presenter and the presented view controllers. 您应该能够从提供的视图控制器中执行
dismiss(animated: true, completion: nil)
,因为Apple库可以处理来自主持人和提供的视图控制器的撤消。 No need to pass a reference 无需传递参考
You also can give a callback to dismiss something like this: 您还可以提供回调以消除以下内容:
helper.add(player: player) {
self.dismiss(animated: true, completion: nil)
}
Player:
public func set(playerController: AVPlayerViewController, completion: (Void)->Void){
completion()
}
Try like this from your helper class:- 在您的帮助程序类中尝试以下操作:-
AppDelegate.sharedInstance().window?.topMostController()?.dismiss(animated: true, completion: nil)
And add this function in your AppDelegate file :- 并将此功能添加到您的AppDelegate文件中:
class func sharedInstance() -> AppDelegate{
return UIApplication.shared.delegate as! AppDelegate
}
