没有调用Swift 3 viewWillTransitionToSize

Question

我的swift 3代码中有这个方法：

func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {
}

我尝试了以下内容：

override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {
}

但是我收到了这个错误：

Method does not override any method from its superclass

为什么不调用viewWillTransitionToSize？

Answer 1

尝试

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator){
    super.viewWillTransition(to: size, with: coordinator)
}

Answer 2

关于从swift2.x迁移到Swift3'viewWillTransition'方法的迁移过程已经改变：

<强> Swift2.x

override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator)

<强> Swift3

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator)

使用 将密钥 withTransitionCoordinator 更改为
