无法覆盖存储的属性shouldRemovePresentersView（）

Question

我试图提供我自己的版本来覆盖这种行为，特别是告诉UIKit让MyController保持可见。

import UIKit

class DimmingPresentationController: UIPresentationController {

    override var shouldRemovePresentersView: Bool

}

但我收到了一些错误，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，我正在改写Swift 2方法，这对swift 3来说不方便了：

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

Answer 1

只需删除括号，将func替换为var并使用冒号交换箭头，该方法已转换为属性：

override var shouldRemovePresentersView : Bool {
    return false
}
