斯威夫特3 viewWillTransitionToSize不會被調用

Question

我在SWIFT 3碼有這樣的方法：

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

我曾嘗試以下：

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

，但我得到這個錯誤：

Method does not override any method from its superclass 

爲什麼不調用viewWillTransitionToSize？

Answer 1

嘗試

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

Answer 2

在遷移過程從swift2.x到Swift3 'viewWillTransition' 方法已經改變：

Swift2.x

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

Swift3

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

更改密鑰withTransitionCoordinator到與
