iOS 7 status bar back to iOS 6 default style in iPhone app?

Question

In iOS 7 the UIStatusBar has been designed in a way that it merges with the view like this:

Answer 1

A small alternative to Archy Holt's answer, a bit more simple:

a. Set UIViewControllerBasedStatusBarAppearance to NO in info.plist

b. In AppDelegate's application:didFinishLaunchingWithOptions:, call:

if ([[UIDevice currentDevice].systemVersion floatValue] < 7)
{
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
}
else
{
    // handling statusBar (iOS7)
    application.statusBarStyle = UIStatusBarStyleLightContent;
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
    self.window.clipsToBounds = YES;

    // handling screen rotations for statusBar (iOS7)
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(applicationDidChangeStatusBarOrientationNotification:) name:UIApplicationDidChangeStatusBarOrientationNotification object:nil];
}

And add the method:

- (void)applicationDidChangeStatusBarOrientationNotification:(NSNotification *)notification
{
    // handling statusBar (iOS7)
    self.window.frame = [UIScreen mainScreen].applicationFrame;
}

You can also consider subclassing UIWindow to handle UIApplicationDidChangeStatusBarOrientationNotification itself.
