Universal Link未在iOS 9的应用程序中打开

Posted 2021-04-13

在info.plist文件中创建了URL类型，其URL方案是http。创建了NSUserActivity类型。在'ViewController'类中创建了权利UIWebView。在AppDelegate方法中我实现了以下代码：

func application (application: UIApplication,willContinueUserActivityWithType userActivityType: String) -> Bool  {
    let sharedUserActivityType = "com.test.testApp"
    if (userActivityType == sharedUserActivityType) {
        return true
    }
    return false
}

@available(ios 8.0, *)

internal override func restoreUserActivityState(activity: NSUserActivity) {

    //don't forget to call super!

    if #available(iOS 8.0, *) {

        super.restoreUserActivityState(activity)

        let userInfo = activity.userInfo

    } else {
            // Fallback on earlier versions

    }
}

func application(application: UIApplication, continueUserActivity 
        userActivity: NSUserActivity, restorationHandler: ([AnyObject]?) -> 
        Void) -> Bool {

    if  userActivity == "com.test.testApp.view"
    {
        let mainListing = ViewController()

        restorationHandler([mainListing])
    }

    if let window = self.window 
    {
        window.rootViewController?.restoreUserActivityState(userActivity)
    }

    return true
}

func application(app: UIApplication, openURL url: NSURL, options: 
        [String : AnyObject]) -> Bool {

    return true
}

• 我提到链接https://developer.apple.com/library/archive/documentation/General/Conceptual/AppSearch/UniversalLinks.html#//apple_ref/doc/uid/TP40016308-CH12-SW2
• 创建了名为apple-app-site-association的json文件 { "applinks": { "apps":[], "details": { "teamId.com.test.testApp": { "paths":["*"] } } } }
• 我签署了apple-app-site-association文件，但由于我使用的是iOS9，因此无需签名。
• 我实现了方法应用程序：continueActivity并返回YES。
• 但我的链接不是在app中打开，而是在safari中打开。

答案

您的apple-app-site-association JSON文件格式不正确 - 详细信息词典中缺少appID密钥，即

{ 
  "applinks": 
   { "apps":[], 
     "details": [
       {
         "appID": "teamId.com.test.testApp",  
         "paths":["*"] 
      } 
     ]
    } 
}

你可以使用Apple verification tool来验证这一点。

即使你在iOS9上也要注意，你仍然需要通过https提供apple-app-site-association文件。
