实现“阅读更多”的最简单方法按钮在iOS Swift 2中展开UITextView？

问题描述：

我希望实现一个Read more按钮，它将扩展UITextView，以便有人可以根据需要阅读整个文本。我还没有找到一种简单的方法来实现这一目标。我试着用容器的高度玩，但它没有给我想要的结果。我真的很感激任何想法。

I am looking to implement a "Read more" button that will expand the UITextView so that someone can read the whole text if they wish. I haven't managed to find an easy way to achieve this yet. I tried to "play" with the container's height but it doesn't give me the desired results. I would really appreciate any ideas.

我建议你使用ilyapuchka ReadMoreTextView 库此链接。这是实现这一目标的最简单方法，它是轻量级的。

I would suggest you the ilyapuchka ReadMoreTextView library which is on this link. It is the easiest way to achieve this and it is retty lightweight.

您可以使用CocoaPods安装它，只需实现 pod'ReadMoreTextView'进入podfile，您可以使用它：

You can install it with CocoaPods, just implement pod 'ReadMoreTextView' into the podfile and you can use it likie this:

let textView = ReadMoreTextView()

textView.text = "Lorem ipsum dolor ..."

textView.shouldTrim = true
textView.maximumNumberOfLines = 3
textView.trimText = "Read more"
