objective c - addSubView not working, attempting to switch views -

-

// viewcontroller.m

1: - (ibaction)done:(id)sender { 2: 3:     [self.view removefromsuperview]; 4:     [self.view addsubview:masterviewcontroller]; 4: }

error on line 4: "unexpected interface name masterviewcontroller :expected expression". have 2 view controllers: viewcontroller , masterviewcontroller. i've set first view viewcontroller i'm trying button change view.

you can move first oneviewcontroller anotherviewcontroller using this.

- (ibaction)buttonpressed:(id)sender {     masterviewcontroller *createusercontroller = [[masterviewcontroller alloc] initwithnibname:@"masterviewcontroller" bundle:[nsbundle mainbundle] keywrapper:keychainwrapper];     [self presentviewcontroller:createusercontroller animated:yes completion:nil]; }

and if using uinavigationviewcontroller can push viewcontroller like

[self.navigationcontroller pushviewcontroller:createusercontroller  animated:yes];

and using

[self.navigationcontroller popviewcontroller:createusercontroller animated:yes];
