class ViewController: UIViewController, UITextViewDelegate {
完成后,你可以添加此功能以使键盘在用户按下 Enter 时消失:
func textView(_ textView: UITextView,
shouldChangeTextIn range: NSRange,
replacementText text: String) -> Bool {
if (text == "\n") {
textView.resignFirstResponder()
return false
}
return true
}
最后,你必须通过将以下代码添加到你的
viewDidLoad
函数来通知 iOS,
txtInput
控件
会将 TextView 事件委托给
ViewController
:
txtInput.delegate = self
你现在已准备好允许用户输入文本。那么,接下来,让我们看看如何提取本文中的实体!
