internalContentSize() - 方法不会覆盖其超类中的任何方法 [英] intrinsicContentSize() - Method does not override any method from its superclass

问题描述

我更新到 Xcode 8 beta 5，现在在继承自 UIView 的类上出现以下错误:

I updated to Xcode 8 beta 5, and now get the following error on a class that inherits from UIView:

Method does not override any method from its superclass

override public func intrinsicContentSize() -> CGSize
{
   ...
}

有解决方法吗?

推荐答案

请查看 最新参考.(您只需在 Apple 开发者网站 的搜索栏中输入intrinsicContentSize"一词即可轻松找到它.)

Please check the latest reference. (You can easily find it just putting the word "intrinsicContentSize" in the searchbar of Apple's developer site.)

声明

var intrinsicContentSize: CGSize { get }

intrinsicContentSize 已经变成了计算属性，所以需要这样覆盖:

intrinsicContentSize has become a computed property, so you need to override it in this way:

override open var intrinsicContentSize: CGSize {
    get {
        //...
        return someCGSize
    }
}

或者干脆:

override open var intrinsicContentSize: CGSize {
    //...
    return someCGSize
}
