Answer 1

Here is the code that you should write in app delegate.

UIViewController *vc=[[UIViewController alloc]initWithNibName:@"vc1" bundle:nil];
UIView *view=[[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 568)];
view.backgroundColor=[UIColor redColor];
[vc setView:view];

self.navme=[[UINavigationController alloc]initWithRootViewController:vc];
self.window.rootViewController = self.navme;
