ios - 如何快速读取 UITextInput 中的文本？

Question

我是 swift 的初学者。我有

class A : UIViewController {
var textInput: UITextInput

init(textInput: UITextInput) {
    self.textInput = textInput
}

func getText() -> String() {
    /// Here I need to get the current text from textInput
}

}

如何获得？请帮忙。提前致谢!!!!

swift 3:

let start  = sender.beginningOfDocument
let end = sender.endOfDocument
let range = sender.textRange(from: start, to: end)!

let trimmedText = sender.text(in: range)
sender.replace(range, withText: "new text")
