uinavigationbar - ios UIBarButtonItem with UIBarButtonSystemItemCompose showing red button -

-

i trying add uibarbuttonitem style of uibarbuttonsystemitemcompose. according apple docs should display compose icon consists of square outline. when use following code displays red button. icon work if uibarbuttonitem if placed inside of uitoolbar , not navigation bar.

self.navigationitem.rightbarbuttonitem = [[[uibarbuttonitem alloc]                                           initwithtitle:nil                                           style:uibarbuttonsystemitemcompose                                           target:self                                           action:@selector(tweetpressed:)] autorelease];

you creating button incorrectly. need use proper init... method.

uibarbuttonitem *btn = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem:uibarbuttonsystemitemcompose target:self action:@selector(tweetpressed:)]; self.navigationitem.rightbarbuttonitem = btn; [btn release];

look @ docs init... method used. @ type should passed style parameter , @ valid values are.
