Answer 1

I have achieved status bar like iOS 6 in iOS 7.

Set UIViewControllerBasedStatusBarAppearance to NO in info.plist

Pase this code in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
    [application setStatusBarStyle:UIStatusBarStyleLightContent];
    self.window.clipsToBounds =YES;
    self.window.frame =  CGRectMake(0,20,self.window.frame.size.width,self.window.frame.size.height);

    //Added on 19th Sep 2013
    NSLog(@"%f",self.window.frame.size.height);
    self.window.bounds = CGRectMake(0,0, self.window.frame.size.width, self.window.frame.size.height);
}

It may push down all your views by 20 pixels.To over come that use following code in -(void)viewDidAppear:(BOOL)animated method

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
    CGRect frame=self.view.frame;
    if (frame.size.height==[[NSUserDefaults standardUserDefaults] floatForKey:@"windowHeight"])
    {
        frame.size.height-=20;
    }
    self.view.frame=frame;
}

You have to set windowHeight Userdefaults value after window allocation in didFinishLauncing Method like

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[[NSUserDefaults standardUserDefaults] setFloat:self.window.frame.size.height forKey:@"windowHeight"];
