iphone - segmentedcontrol in navigationbar -

i trying put in navigationbar, doesnt show up, can u have @ it?

uisegmentedcontrol *seg1 = [[uisegmentedcontrol alloc] initwithitems:[nsarray arraywithobjects:@"von mir", @"alle", nil]]; [seg1 setsegmentedcontrolstyle:uisegmentedcontrolstylebar]; uibarbuttonitem *baritem = [[uibarbuttonitem alloc] initwithcustomview:seg1]; uibarbuttonitem *flexitem = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem:uibarbuttonsystemitemflexiblespace target:self action:nil]; [self.navigationcontroller.navigationbar setitems:[nsarray arraywithobjects:flexitem, baritem, flexitem, nil]]; [flexitem release]; [baritem release]; [seg1 release]; 

uinavigationbar's items property accepts array of uinavigationitem objects, not uibarbuttonitem objects. can't configure navigation bar same way uitoolbar. instead, in view controller, this:

uisegmentedcontrol * seg1 = [[uisegmentedcontrol alloc]     initwithitems:[nsarray arraywithobjects:@"von mir", @"alle", nil]]; [seg1 setsegmentedcontrolstyle:uisegmentedcontrolstylebar]; self.navigationitem.titleview = seg1; 

this adds segmented control title view of view controller's navigation item, custom view appears centered on navigation bar.
