swift - 导航设置总结加深记忆

一.创建导航

    let VC=ViewController()
    let navigationC = UINavigationController(rootViewController: VC)
    self.window?.rootViewController=navigationC
    self.window?.backgroundColor=UIColor.white

二.导航栏标题颜色

self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor:UIColor.white];

三.导航条颜色

self.navigationController?.navigationBar.barTintColor = UIColor.white;

四.设置导航左右点击按钮

右:

let rightButton = UIButton(type: UIButtonType.custom)
        rightButton.frame = CGRect(x: 0, y: 0, width: 33, height: 32)
        rightButton.addTarget(self,action:#selector(ViewController.buttonAtion),for:UIControlEvents.touchUpInside)
        rightButton.setTitle("123", for: UIControlState.normal)
        let rightItem = UIBarButtonItem(customView: rightButton)
        self.navigationItem.rightBarButtonItem = rightItem

点击事件:

@objc func buttonAtion(button:UIButton){
          print("22按钮点击了")
      }
