not writing your code here -- but giveng you a detailed instruction of how to use a NSTimer ;) [note that this is just one way but IMHO it is the easiest/most intuitive]

  1. set yourself as delegate of textfield

  2. wait for didBegin notification and set the timer for cancel Editing to 2s there!

  3. if endEditing is called while timer is active, cancel it

  4. if shouldChangeCharacters is called while timer is active, cancel it

  5. if timer wasn't cancelled and fires. tell the textfield to endEditing
