不能用存储的属性覆盖 shouldRemovePresentersView()

Question

我正在尝试提供我自己的版本来覆盖其中的一些行为，特别是告诉 UIKit 让 MyController 可见。

import UIKit

class DimmingPresentationController: UIPresentationController {

    override var shouldRemovePresentersView: Bool

}

但我收到几个错误，例如：

Cannot override with a stored property 'shouldRemovePresentersView'
Getter for 'shouldRemovePresentersView' with Objective-C selector 'shouldRemovePresentersView' conflicts with getter for 'shouldRemovePresentersView' from superclass 'UIPresentationController' with the same Objective-C selector

实际上，我正在重写 Swift 2 方法，这不再方便 swift 3：

override func shouldRemovePresentersView() -> Bool {
return false
}

Answer 1

只要去掉括号，把func换成var，把箭头换成冒号，方法就变成了属性：

override var shouldRemovePresentersView : Bool {
    return false
}
