with code tab there no navigation bar @ top of tab.

can suggest must resolve this?

if require more information feel free ask , edit bottom of question. in advance :)

if want navigation bar @ top should fill tabbar controller navigation controllers inited root controllers, not plain controllers. smth that:

takenviewcontroller *viewcontroller2 = [[takenviewcontroller alloc] init]; medslistviewcontroller *viewcontroller1 = [[medslistviewcontroller alloc] init]; medsalarmviewcontroller *viewcontroller3 = [[medsalarmviewcontroller alloc] init]; uinavigationcontroller * nc1 = [[uinavigationcontroller alloc] initwithrootviewcontroller:viewcontroller1]; uinavigationcontroller * nc2 = [[uinavigationcontroller alloc] initwithrootviewcontroller:viewcontroller2]; uinavigationcontroller * nc3 = [[uinavigationcontroller alloc] initwithrootviewcontroller:viewcontroller3];  self.viewcontrollers = [nsarray arraywithobjects:nc1,                                 nc2,                                 nc3,nil];
