cocoa touch - UILabel UITextField UITextView

What's the fundamental difference between them?

Is a UITextField that's not editable is effectively a UILabel?

Are those essentially the same?

  • UILabel: "The UILabel class implements a read-only text view."
  • UITextField: "A UITextField object is a control that displays editable text and sends an action message to a target object when the user presses the return button."
  • UITextView: "The UITextView class implements the behavior for a scrollable, multiline text region."

So:

  • labels are read-only
  • textfields are editable, and provide horizontal character seeking (not really scrolling) when the text is too long to display all at once. Generally used to input short text.
  • textviews are also editable, but provide vertical scrolling when the text is too long to display all at one.
