file's owner of xib is not what i expect

i'm using xcode4. i have a xib window (perhaps copyed by another one, i forgot because i have made it some times ago) named: chooseCharacter.xib i have the chooseCharacter.h and .m as view controller (i thought) i have added

-(IBAction)doneButtonClick;

on the chooseCharacter.h but i've not seen it in interface builder actions... i have added this on HighScoreViewController.h and it now shows up... however, if i put it on HighScoreViewController.h i must put the implementation in chooseCharacter.m or i get

-[ChooseCharacter doneButtonClick]: unrecognized selector se开发者_如何学运维nt to instance 0xcc0d9b0'

seems that the window is binded with a file's owner that is HighScoreViewController.h but search implementation in ChooseCharacter.m!!!

how can i bind the xib to the right file? thanks

found it. selecting in interface builder, file's owner and clicking in identity inspector under class was HighScoreViewController, changed to chooseCharacter now it works
