uitableview - detecting text change in uitextfied? -

i detect change in uitextfield , when ever there change in uitextfield call method provide me code showing how that.

thanks, tc

the uitextfield calls method on delegate when user has entered new text:

- (bool)textfield:(uitextfield *)textfield shouldchangecharactersinrange:(nsrange)range replacementstring:(nsstring *)string 

here's reference methods uitextfield can call on delegate.

you can return no method if don't want allow change. can set delegate of uitextcontrol this:

mytextfield.delegate = myobjthatisthedelegateforthistextfield; 

it may setup in xib file, though.

edit

to connect uitextfield if you're using interfacebuilder, right-click on uitextfield in window , drag line cube represents view controller (probably third cube in myview.xib?) select delegate popup appears.
