ios - UIBarButtonItem - changing background and removing text -

i'm trying change done button in presentviewcontroller in navbar succesfully able change background using this:

[[uinavigationbar appearance] setbackgroundimage:[uiimage imagenamed:@"nav_bg.png"] forbarmetrics:uibarmetricsdefault]; 

now, when changing done button replacing image, image repeating , done text stays there. using this:

uiimage *donebackgroundimage = [[uiimage imagenamed:@"back-home.png"]                                             resizableimagewithcapinsets:uiedgeinsetsmake(0, 0, 0, 0)];              [[uibarbuttonitem appearance] setbackgroundimage:donebackgroundimage                                                     forstate:uicontrolstatenormal                                                        style:uibarbuttonitemstyledone                                                   barmetrics:uibarmetricsdefault];
