Question

I have added a image on navigationcontroller in appdelagte class.
and set yes in

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    loginViewController = [[LoginViewController alloc]initWithNibName:@"LoginViewController" bundle:nil];

    [self.window addSubview:_navController.view];

    _navController.navigationBarHidden = NO;
    navimage = [[UIImageView alloc] init];
    navimage.frame = CGRectMake(300, 18, 177, 47);

    navimage.image = [UIImage imageNamed: @"logo.png"];  

    [_navController.view addSubview:navimage];
    [self.window makeKeyAndVisible];
    return YES;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
return YES;
}  

But navigation image position is not changing. The frame remains same in both modes.

Please give me idea how it will be solved in the case of navigation controller image.

Answer 1

You should add this in your controllers viewDidLoad method and shouldAutorotateToInterfaceOrientation in your controller.

-(void)viewDidLoad{
 navimage = [[UIImageView alloc] init];
 navimage.frame = CGRectMake(300, 18, 177, 47);

 navimage.image = [UIImage imageNamed: @"logo.png"];  

 [_navController.view addSubview:navimage];
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
 return UIInterfaceOrientationIsPortrait(toInterfaceOrientation);
}
