xcode 添加故事板视图作为以编程方式创建的视图的子视图

Add a storyboard view as a subview of a programmatically created view

提问by JeffN

I have created a special class of UIView that has certain properties, and I did so programmatically because it is usually blank but will at times contain other views. I know that if I create a UIView programmatically I can do something like [specialView addSubview: aView];

我创建了一个特殊的 UIView 类，它具有某些属性，我以编程方式这样做，因为它通常是空白的，但有时会包含其他视图。我知道如果我以编程方式创建 UIView 我可以做类似的事情[specialView addSubview: aView];

My problem is that there is a UIView that I created in storyboard and I need to add that UIView as a subview on my special view. I have connected it as a property in my ViewController but when I do the same code as above, nothing happens. Thoughts?

我的问题是我在故事板中创建了一个 UIView，我需要将该 UIView 添加为我的特殊视图的子视图。我已将它连接为 ViewController 中的一个属性，但是当我执行与上述相同的代码时，没有任何反应。想法？

MyViewController *myViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"MyScene"]; 
[specialView addSubview:myViewController.theViewToAdd]; 

And don't forget to give such an identifier to your scene (view controller) in Interface Builder.

并且不要忘记在 Interface Builder 中为您的场景（视图控制器）提供这样的标识符。

Another solution is you can add the viewcontroller as a childviewcontroller.

另一种解决方案是您可以将视图控制器添加为子视图控制器。

    func displayContentController(content: UIViewController) {
    addChildViewController(content)
    self.view.addSubview(content.view)
    content.didMoveToParentViewController(self)
}

To remove :

去除 ：

func hideContentController(content: UIViewController) {
    content.willMoveToParentViewController(nil)
    content.view.removeFromSuperview()
    content.removeFromParentViewController()
}

That UIViewController which houses the view you want may not be instantiated. So you would need to instantiate that controller and grab the view from there.

容纳您想要的视图的 UIViewController 可能不会被实例化。因此，您需要实例化该控制器并从那里获取视图。
