Swift 3 viewWillTransitionToSize 未被调用

Question

我的 swift 3 代码中有这个方法:

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

我尝试了以下方法:

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

但是我得到这个错误:

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)
}
