White screen when launched in build

Question

Whenever i launch an app with text, i get a white screen (there is 1 more scene). i have tried remaking it and deleting this code. It is on X code and started from the preset "empty Application"

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];

GOt this is in debugging

i expected to see a table saying address and all i saw was a white screen. Any reason known?

Can you expand on "It didn't work"? Please explain 1) what you expected, and 2) what you saw instead. If there is an error message, show that too. Don't reply in comments - edit your question to add it. — Taryn East, Jul 17 '14 at 01:35

Your UIWindow is missing a root view controller, i.e:

self.window.rootViewController = [[UIViewController alloc] init];

where did you put it, should be before makeKeyAndVisible. – Shams Ahmed Jul 18 '14 at 18:39
`self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. self.window.backgroundColor = [UIColor whiteColor]; self.window.rootViewController = [[UIViewController alloc] init]; [self.window makeKeyAndVisible]; return YES;` – Rish Jul 21 '14 at 18:19
