添加覆盖屏幕内容的自定义导航栏

Question

我通过故事板添加了自定义导航栏。我期待屏幕上的内容自动向下移动。但它完全覆盖了屏幕顶部的内容..是否有一行简洁的代码会自动在导航栏和视图本身之间创建间距？

规格只需拨打从viewDidLoad中此方法：

func createNavBar() { 

     let leftNavigationButton = UIButton() 
     leftNavigationButton.setImage(UIImage(named: "ic_back.png"), forState: .Normal) 
     leftNavigationButton.frame = CGRectMake(10, 10, 20, 15) 
     leftNavigationButton.addTarget(self, action: "onBackButtonPressed:", forControlEvents: UIControlEvents.TouchUpInside) 
     let customBarItem = UIBarButtonItem(customView: leftNavigationButton) 
     self.navigationItem.leftBarButtonItem = customBarItem; 

     //set TitleAppIcon 
     let GR = UITapGestureRecognizer(target: self, action: Selector("headerLogoTapAction:")) 
     let imageView = UIImageView(frame: CGRect(x: 90, y: 0, width: ((UIScreen.mainScreen().bounds.width)/3), height: 40)) 
     imageView.contentMode = .ScaleAspectFit 
     let image = UIImage(named: "yourimag.png") //or set title 
     imageView.image = image 
     imageView.addGestureRecognizer(GR) 
     imageView.userInteractionEnabled = true 
     navigationItem.titleView = imageView 
    }
