Disable Paste into UITextField

In case you need to disable the "Paste" operation, for security reasons for example, this is the class you're searching for:

class NoPasteField: UITextField {    override func canPerformAction(action: Selector, withSender sender: AnyObject?) -> Bool {        if action == "paste:" {            return false        }        return super.canPerformAction(action, withSender: sender)    } }

Delegate

func textFieldShouldReturn(sender: UITextField). Often it will just be to resign from the first responder. It’s what happens when return key is pressed.

UITextField

UILabel, but editable. Relies on delegation. wtf is delegation?

Keyboard appears when UITextField becomes “first responder”. You do that automatically when user taps on it. Or you can send a becomeFirstResponder message. You can also send resignFirstResponder to the UITextField.

[iOS] How to set the Text-Inset of UITextField?

개발을 하다 보면, UITextField의 텍스트 부분 Inset을 설정해야할 때가 있다.

스택오버플로우의 답변을 보면 참 쉽게 할 수 있다.

1. UITextField의 subclass를 만든다.

2. textRectForBounds: 와 editingRectForBounds: 메서드에서 원하는 CGRect 값을 반환하면 된다.

참 쉽다 >_<

2015년 1월 30일 수정

textRectForBounds:는 placeholder의 inset을, editingRectForBounds: 에서는 사용자가 입력하는 텍스트 (.text)의 inset을 return해주면 된다.
