如何遍历我的Swift视图中的所有UIButton？ [英] How to loop through all UIButtons in my Swift view?

问题描述

如何在Swift的视图中循环遍历所有 UIButtons ？我想将所有标题设置为，但我在Swift中的for循环发出错误。

How would I loop through all UIButtons in my view in Swift? I would want to set all the titles to "", but my for-loop in Swift is giving an error.

for btns in self.view as [UIButton] {
  // set the title to ""
}

推荐答案

此代码应该有效：

for view in self.view.subviews as [UIView] {
    if let btn = view as? UIButton {
        btn.setTitleForAllStates("")
    }
}

你需要遍历subViews数组。

You need to iterate through the subViews array.
