添加覆蓋屏幕內容的自定義導航欄

Question

我通過故事板添加了自定義導航欄。我期待屏幕上的內容自動向下移動。但它完全覆蓋了屏幕頂部的內容..是否有一行簡潔的代碼會自動在導航欄和視圖本身之間創建間距？

您可能已經聽說過Cocpods，我覺得這是一個更好的方式去找fragom導航欄。 你只需要實現的協議，給你需要的導航欄中 經過以下閉門

規格只需撥打從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 
    } 

希望這會幫助你
