in firstviewcontroller
1, keep member variable(nsstring) named detailtextvaluefromsecondcontroller.
2, create function named
-(void)refreshtabletosetdetailtext:(nsstring *)detailtextvalue then in secondviewcontroller
inside
- (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath place following code:
for (int =0; < [[self.navigationcontroller viewcontrollers] count]; i++) { uiviewcontroller *acontroller = [[self.navigationcontroller viewcontrollers] objectatindex:i]; if ([acontroller iskindofclass:[firstviewcontroller class]]) { firstviewcontroller *afirstviewcontroller = (firstviewcontroller *)acontroller; [afirstviewcontroller refreshtabletosetdetailtext:yourstringtosetondetaillabel]; [self.navigationcontroller poptoviewcontroller:acontroller animated:yes]; } }
