ios7 set status bar

You have to do 2 things. 

First is to open your info.plist and set "View controller-based status bar appearance" = NO

And the second is to add this lines to application:didFinishLaunchingWithOptions

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7)
{   
    self.window.clipsToBounds = YES;
    [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleBlackOpaque];     

    UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
    if(orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight)
    {
        self.window.frame =  CGRectMake(20, 0,self.window.frame.size.width-20,self.window.frame.size.height);
        self.window.bounds = CGRectMake(20, 0, self.window.frame.size.width, self.window.frame.size.height);
    } else
    {
        self.window.frame =  CGRectMake(0,20,self.window.frame.size.width,self.window.frame.size.height-20);
        self.window.bounds = CGRectMake(0, 20, self.window.frame.size.width, self.window.frame.size.height);
    }
}
