It's not even necessary to implement the delegate. I greatly prefer using good, old-fashioned target/action pattern to handle this. It can also lead to cleaner code if you have multiple ways of ending editing (say, intercepting touches outside the text field to cancel editing).

To use target/action, simply wire up UIControlEventEditingDidEndOnExit, which shows up in Interface Builder as the Did End On Exit event.

No muss, no fuss. A lot cleaner and easier than implementing the delegate.
