Navigate from a view to another

The main: xxxVieContro开发者_StackOverflow社区ller and the second: OptionViewController

in xxxView controller I have

.h
@interface iMetroAlertViewController : UIViewController {

    IBOutlet UIButton *option;
}

-(IBAction) goToOption;

and

.m
@implementation iMetroAlertViewController

-(IBAction) goToOption{
    NSLog(@"Works");
    OptionViewController *dvController = [[OptionViewController alloc] initWithNibName:@"OptionView" bundle:[NSBundle mainBundle]];
    [self.navigationController pushViewController:dvController animated:YES];
    [dvController release];
    dvController = nil;
}

Of course a OptionViewController.xib, .m and .h are created...

When I push on the button, nothing happens (the link is done cause I have an NSLog

I don't understand why it doesn't work

It probably doesn't work because you don't have a navigation controller, so calling self.navigationController returns nil.

First you have to create the navigation controller

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
 {   
    RootViewController *mainMenuVC = [[RootViewController alloc] init];   
    navigationController = [[UINavigationController alloc] initWithRootViewController:mainMenuVC];
    [self.window addSubview:navigationController.view];
    [self.window makeKeyAndVisible];
    return YES;
}
