ios - Push View Controller From AppDelegate and Tab Bar -

my app setup tab bar controller rootviewcontroller, , each tab has navigationcontroller in it. when actions performed, want app force viewcontroller onto screen. flow of when app starts, or opens background, checks stored nsdate , compares current date. if right status met, shows uialertview. if button named "push" selected, runs code force new view. reason need ran appdelegate, there no guarantee tab may open if app beingness used in background. since every tab contains navigationcontroller, thought run appdelegate:

- (void)alertview:(uialertview *)alertview clickedbuttonatindex:(nsinteger)buttonindex { if (alertview.tag == 100) { if (buttonindex == 0) { //cancel nslog(@"cancel"); } if (buttonindex == 1) { nslog(@"ok"); [self.tabbarcontroller.selectedviewcontroller pushviewcontroller:self.newview animated:yes]; } } }

i warning message says uiviewcontroller may not respond -pushviewcontroller:animated. suggestions else do?

the homecoming type selectedviewcontroller uiviewcontroller, need tell compiler it's navigation controller. cast,

[(uinavigationcontroller *)self.tabbarcontroller.selectedviewcontroller pushviewcontroller:self.newview animated:yes];

ios uinavigationcontroller uitabbarcontroller appdelegate pushviewcontroller
