How to programmatically create UIView so that it does not overlap the status bar - ios

Question

I am using the following code in my app delegate to programmatically create the application's window and root controller:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = [[UIViewController alloc] init];
self.window.rootViewController.view = [[UIView alloc] init];
self.window.rootViewController.view.backgroundColor = [UIColor redColor];
return TRUE;
}
The code works fine, however the view associated to the root view controller overlaps the status bar, which I would like to avoid (see picture below).
How should I proceed? In particular I want to have a lightgray background for the status bar (similar to the apps created with a storyboard) and also handle orientation change correctly.
Thanks

Well, you can do something as following:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = [[UIViewController alloc] init];
self.window.rootViewController.view.backgroundColor = [UIColor whiteColor];
UIView *redView = [[UIView alloc] initWithFrame:CGRectMake(0,
[UIApplication sharedApplication].statusBarFrame.size.height,
[UIScreen mainScreen].bounds.size.width,
[UIScreen mainScreen].bounds.size.height)];
redView.backgroundColor = [UIColor redColor];
[self.window.rootViewController.view addSubview:redView];
[self.window makeKeyAndVisible];
return TRUE;
}
should look like this:
