Swift:如何检测 UIView 中的元素? [英] Swift: How can I detect elements inside of a UIView?

问题描述

我想知道两件事(我是 Swift 初学者):

I am wondering two things (I am a Swift beginner):

1) 有没有办法检测或目标元素(子元素)在给定的 UIView 内.

1) Is there a way to detect or target elements (children) are inside a give UIView.

2) UIView 中的元素是否存储在数组中?

2) Are the elements inside the UIView stored in an array?

举个例子，假设我有一个名为 parentView 的 UIView，它有一个 ImageView(称为 imageChildre)和一个 LabelView(称为labelChildre)

As an example let say I have a UIView called parentView and it has inside an ImageView (called imageChildre) and a LabelView (called labelChildre)

我如何定位孩子?

感谢您的帮助

推荐答案

1. 这样的事情?您可以相应地更改条件.

1. Something like this? You can change condition accordingly.

for subview in parentView.subviews
{
    if let item = subview as? UIImageView
    {
        //this is image view
    }
}

parentView.subviews 是 parentView
