应用程序的实现:openURL:sourceApplication:annotation

Question

我在Xcode8发布之前开始研究应用程序然后切换,当我尝试使用Facebook登录登录应用程序时出现以下错误

应用程序的实现:openURL:sourceApplication:annotation:not found.请将处理程序添加到App Delegate中.类:GhostGab.AppDelegate

我检查了所有的设置,他们似乎很好.任何帮助将不胜感激

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    FIRApp.configure()
    FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
    return true
}

  func application(application: UIApplication, openURL url: URL, sourceApplication: String?, annotation: AnyObject) -> Bool {

    let facebookDidHandle = FBSDKApplicationDelegate.sharedInstance().application(
        application,
        open: url,
        sourceApplication: sourceApplication,
        annotation: annotation)
    // Add any custom logic here.
    return facebookDidHandle
}

Answer 1

你的功能定义:

func application(application: UIApplication, openURL url: URL, sourceApplication: String?, annotation: AnyObject) -> Bool {
}

应该替换为:

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
}

第一个参数有一个下划线Any,代替AnyObject最后一个参数类型.

这就是你收到错误的原因:
