addSubView not working, attempting to switch views

Question

// 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". I have two view controllers: ViewController and MasterViewController. I've set it up so that the first view is a ViewController but I'm trying to get a button to change the view.

Answer 1

You Can Move First OneViewController to 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 you Using UINavigationViewController you can push the ViewController like

[self.navigationController pushViewController:createUserController  animated:YES];

and back using

[self.navigationController popViewController:createUserController animated:YES];

Answer 2

MasterViewController *obj = [MasterViewController alloc]init];
self.navigationController pushViewController:obj animated:YES];

you can use this code snippet .This will push a new view controller. and will give u a back button functionality to go to previous view controller.
