Question

This question might have been answered, if yes, please share the link.

I have created a Single View Application, It works fine, but now I have added a new view and on a button click, wants the new view to appear.

This is the code for click action,

    SettingsViewController *settingsViewController = [[SettingsViewController alloc] initWithNibName:@"SettingsViewController" bundle:[NSBundle mainBundle]];

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

The Default ViewController now looks like this in .h file

    @interface ViewController : UIViewController<UIImagePickerControllerDelegate, UINavigationControllerDelegate>

The SettingsViewController.m has a default

    - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil{}

Can I add another view to “Single View Application” like this or should I chose another template for my project ?

Thanks.

You need to create a UINavigationController in your AppDelegate. Then make your ViewController the rootViewController of the UINavigationController. Then you will be able to push and pop views.

Here is the code to create the rootViewController where mainNavigationController is the UINavigationController in your AppDelegate:

ViewController *vc = [[ViewController alloc] init];
mainNavigationController = [[UINavigationController alloc] initWithRootViewController:vc];

Once you have the ViewController set up as the rootViewController it will conform to the UINavigationController push and pop methods to create a stack of UIViewControllers.
