swift - 如何从 Swift 中的段落开始到 UITextView

Question

如何在 UITextView 中开始一个带有一点空间的新行，我相信称为段落？

Answer 1

你需要做的是让 Controller 面对 UITextFieldDelegate

例如:

class ViewController: UIViewController,UITextFieldDelegate 
{
   //link the textfield
   @IBOutlet weak var textField: UITextField!

   override func viewDidLoad() 
   {
      super.viewDidLoad()
      // link the delegate to the textfield
      textField.delegate = self   
   }

    //this function detects the return button when it's pressed

   func textFieldShouldReturn(_ textField: UITextField) -> Bool 
   {
    //since we always want to start a new line with space we override the default function

     textField.text += "\n "
     return false
}
