Swift 导航栏的使用

一、基本使用

1.1 创建导航栏

在AppDelegate 如下方法中添加创建导航栏的代码：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {        self.window?.backgroundColor = UIColor.whitelet main = ControlMainController()let navigation = UINavigationController(rootViewController: main)self.window?.rootViewController = navigationreturn true
}

1.2 导航栏上添加按钮

//添加导航栏左边按钮
let item1 = UIBarButtonItem(title: "我的", style: UIBarButtonItem.Style.plain, target: self, action: #selector(buttonClick))
self.navigationItem.leftBarButtonItem = item1//添加导航栏右边按钮
let item2 = UIBarButtonItem(title: "设置", style: UIBarButtonItem.Style.plain, target: self, action: #selector(buttonClick))
self.navigationItem.rightBarButtonItem = item2//添加多个按钮
let item1 = UIBarButtonItem(title: "我的", style: UIBarButtonItem.Style.plain, target: self, action: #selector(buttonClick))
let item2 = UIBarButtonItem(title: "设置", style: UIBarButtonItem.Style.plain, target: self, action: #selector(buttonClick))
self.navigationItem.rightBarButtonItems = [item1, item2]

1.3 页面跳转

//跳转到下个页面
func buttonClick(button:UIButton) {let secondVC = SecondViewController()self.navigationController?.pushViewController(secondVC, animated:true)
}
//返回上一个页面
func back() {self.navigationController?.popViewControllerAnimated(true)
}
