UPDATE(NEW SOLUTION)

This update is the best solution of iOS 7 navigation bar problem.You can set navigation bar color example: FakeNavBar.backgroundColor = [UIColor redColor];

Note : If you use default Navigation Controller please use old solution.

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

    if(NSFoundationVersionNumber >= NSFoundationVersionNumber_iOS_7_0)
    {
        UIView *FakeNavBar = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 20)];
        FakeNavBar.backgroundColor = [UIColor whiteColor];

        float navBarHeight = 20.0;
        for (UIView *subView in self.window.subviews) {

            if ([subView isKindOfClass:[UIScrollView class]]) {
                subView.frame = CGRectMake(subView.frame.origin.x, subView.frame.origin.y + navBarHeight, subView.frame.size.width, subView.frame.size.height - navBarHeight);
            } else {
                subView.frame = CGRectMake(subView.frame.origin.x, subView.frame.origin.y + navBarHeight, subView.frame.size.width, subView.frame.size.height);
            }
        }
        [self.window addSubview:FakeNavBar];
    }

    return YES;

}

OLD SOLUTION - IF you use previous code please ignore following Code and Image

This is old version of iOS 7 navigation bar solution.

I solved the problem with the following code. This is for adding a status bar. didFinishLaunchingWithOptions

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
    UIView *addStatusBar = [[UIView alloc] init];
    addStatusBar.frame = CGRectMake(0, 0, 320, 20);
    addStatusBar.backgroundColor = [UIColor colorWithRed:0.973 green:0.973 blue:0.973 alpha:1]; //change this to match your navigation bar
    [self.window.rootViewController.view addSubview:addStatusBar];
}

And for Interface Builder this is for when you open with iOS 6; it is starting at 0 pixels.

Note: iOS 6/7 Deltas only appear if you uncheck "Use Autolayout" for the View Controller in the "File Inspector" (left-most icon) in the details pane.
