regfielddone not member of cell (table view cell). member of class register device view controller. if trying set regfielddone's delegate self, change statement regfielddone.delegate = self

edit: can directly set text field's delegate registerdeviceviewcontroller (file owner) xib file.

you have set regfielddone's delegate self, other textfield's delegate? when edit other textfield's, delegate method not called.

you should notice shouldchangecharactersinrange... method gets called while editing regfielddone , doesnt while editing other textfield's. advice set textfield's delegate self, either programatically or xib file.
