我想在点击文本框时删除文本

Question

I'm making an easy app where I have textFields. When the app starts I have examples in my textfields. I want these text examples to be deleted when users tap on textField. Can anybody help me?

Answer 1

You can set Placeholder text in UITextField . Whenever, UITextField is tapped placeholder text disappears.

Alternatively, you can use following UITextFieldDelegate method

Objective-C

 - (void)textFieldDidBeginEditing:(UITextField *)textField {
   textField.text = ""
}

Swift

func textFieldDidBeginEditing(textField: UITextField) {
  textField.text = ""
}

Answer 2

Just add this underneath your didMoveToView method in youre SpriteKit Game

override func touchesBegan(touches: Set<UITouch>, with Event event: UIEvent?) {

for touch in touches {
    let location = touch.locationInNode(self)
       if nodeAtPoint(location) = textField {
          textField.removeFromParent()
            }
       }
     }

I think you are trying to create text field with placeholder.
