Swift URL Schemes使用

URL Schemes通常用於分享和第三方登錄,但有時需要在html跳至APP,或者APP跳至另外一個APP.這時也需要使用URL Schemes.

一.html跳轉至APP

eg:html跳轉至test1

在APP中添加URL Schemes,這里的URL Schemes隨意寫均可,如圖:

2.在AppDelegate.swift中加入,func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject])
    -> Bool這個方法:

//MARK: - 通過下面的方法實現點擊html可以打開app
  func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject])
    -> Bool {
      if url.host == nil
      {
        return true;
      }
      let urlString = url.absoluteString  //url 的絕對字符串
      let queryArray = urlString.componentsSeparatedByString("/")  //通過/把URL切成數組
      //傳參
//      let alertController = UIAlertController(title: "參數如下",
//                                              message: "\(queryArray[2])  \(queryArray[3])", preferredStyle: .Alert)
//      let cancelAction = UIAlertAction(title: "取消", style: .Cancel, handler: nil)
//      alertController.addAction(cancelAction)
//      self.window!.rootViewController!.presentViewController(alertController, animated: true, completion: nil)
      //打開相應界面
      let tababarController = self.window!.rootViewController!.childViewControllers[0] as! UITabBarController
      if queryArray[2] == "item1" {
        tababarController.selectedIndex = 0  //使tabcarController選中第一個tabbaritem
      }else if queryArray[2] == "item2"{
        tababarController.selectedIndex = 1  //使tabcarController選中第二個tabbaritem
      }
      //測試方法:
      //先安裝test1
      //打開瀏覽器地址欄輸入
      //  test1://       打開test1
      //  test1://item1  打開test1的第一個item
      //  test1://item2  打開test1的第二個item
      //上面的test1就是工程中配置的URL Schemes
      return true
  }

二.APP打開APP

eg:test1打開test2

先在test2中配置URl Schemes,然后在test1中寫代碼即可:

在點擊test1中的一個按鈕時,在其點擊方法中通過openURL打開即可.

 @IBOutlet var btn: UIButton!
    override func viewDidLoad() {
        super.viewDidLoad()
      btn.addTarget(self, action: #selector(Tab2ViewController.btnClick), forControlEvents: .TouchUpInside)
        // Do any additional setup after loading the view.
    }
   func btnClick(){
    let urlString = "test2://"
    let url = NSURL(string: urlString)
    UIApplication.sharedApplication().openURL(url!)
   }

同時,因為iOS9的安全因素,需要在test1中設置白名單.設置方法參考:http://www.cnblogs.com/shaoting/p/5148323.html
