用 ViewContainer 中的按钮隐藏视图容器 [英] Hide a view container with a button in the ViewContainer

问题描述

我有一个视图.在这个视图中，我有一个 Container View.在 ContainerView 我有一个按钮.

I have a View. In this view, I have a Container View. And in the ContainerView I have a button.

当我触摸 ContainerView 的按钮时，我希望 ContainerView 被隐藏.

When I am touching the button of the ContainerView, I want the ContainerView become hidden.

我想做这样的事情:

class ContainerView: UIViewController {

    @IBAction func closeContainerViewButton(sender: AnyObject) {
        //I try this : self.hidden = false
        //or this :    self.setVisibility(self.INVISIBLE)
    }

}

知道怎么做吗?

推荐答案

有多种方法，但这里是最简单的一种，虽然不是最漂亮的.你真的应该使用委托，但这是一种入门的方式.只需创建一个包含容器的类的全局变量(在本例中为 startController).然后从您的其他视图控制器 (MyViewInsideContainer) 调用它并告诉它隐藏您所在的视图.我没有运行此代码，但它应该可以工作.

There are serval ways but here is the easiest one, not prettiest though. You should really use delegates but this is a hacky way to get started. Just create a global variable of the class that holds the container (startController in this case). Then call it from your other view controller (MyViewInsideContainer) and tell it to hide the view you´re in. I have not run this code but it should work.

var startController = StartController()

class StartController:UIViewController {

    @IBOutlet var myViewInsideContainerView: UIView

    ....

    override func viewDidLoad() {
        super.viewDidLoad()
        startController = self
    }

    func hideContainerView(){
        self.myContainerView.hidden = true
    }
}

class MyViewInsideContainer:UIViewController {

    ...

    @IBAction func hideThisView(sender: AnyObject) {
        startController.hideContainerView()
    }

}
