什么是makeObjectsPerformSelector的快速等价物？ [英] What is the swift equivalent of makeObjectsPerformSelector?

问题描述

在Objective-C中我使用此代码删除任何子视图：

In Objective-C I'm using this code to remove any sub-views:

[self.view.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];

但如何在swift中使用它？我看到 apple文档在swift中使用该方法

But how to use it in swift? I saw apple documentation to use that method in swift

func makeObjectsPerformSelector(_ aSelector: Selector)

但是当我尝试它时，我收到一个错误：'AnyObject []'没有名为'makeObjectsPerformSelector'的成员

but when I try it, I get an error: 'AnyObject[]' does not have a member named 'makeObjectsPerformSelector'

有没有办法在swift中删除子视图？

Are there any ways to remove sub-views in swift?

推荐答案

更新了Swift 2.0（Xcode 7）

使用 forEach ：

self.view.subviews.forEach { subview in
    subview.removeFromSuperview()
}

或者像这样：

view.subviews.forEach { $0.removeFromSuperview() }
