Question

I have two view controllers named “view1ViewController” and “view2ViewController” in an cocoa touch project, and they are both linked to a UIView in the storyboard. Say I put a button in view1. Codewise, what’s the easiest way to switch to view2 after I press that button? What code should I need to type to get this to work?

— Update —

Despite what you have all told me about this, I still can’t get this to work. Maybe I’m not getting something? Do I need to add something else? Here is the code for view1ViewController.m:

#import "view1ViewController.h"
#import "view2ViewController.h"


@interface view1ViewController ()

@property (nonatomic, strong) view2ViewController *controller;

@end

@implementation view1ViewController
@synthesize controller = _controller;

- (view2ViewController *)controller
{
    if (!_controller) {
        _controller = [[view2ViewController alloc] init];
    }
    return _controller;
}

- (IBAction)buttonPressed {
    [self.navigationController pushViewController:self.controller animated:YES];
}
@end

I haven’t touched the other files and made sure to set the class of the added view in the storyboard to view2ViewController.

Just

[self.navigationController pushViewController:view2ViewController animated:YES];

simple result you could be able to find yourself just googling a while…

I assumed your app is navigation-based. If this is not the case, you’ll need to init a UINavigationController. For example in your app delegate, in your didFinishLaunchingWithOptions: method, you may do something like

navigationController = [[UINavigationController alloc] init];
[self.window addSubview:navigationController.view];
[navigationController pushViewController:self.viewController animated:NO];

[self.window addSubview:navigationController.view];
[self.window makeKeyAndVisible];

where navigationController is a UINavigationController set as @property.

If you do not want to setup a UINavigationController you may chose to present the other view modally using

[self presentModalViewController:view2ViewController animated:YES];
