Question

我按照here的说明进行了操作，但由于指令是在Objective C中，而我的AppDelegate文件是用Swift编写的，所以我无法通过连接app delegate来获得第5步。

我试过了：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
    // Add any custom logic here.
    return true
}

func application(_ application: UIApplication, open url: URL, options: (UIApplicationOpenURLOptionsKey & id)) -> Bool {
    let handled: Bool = FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey], annotation: options[UIApplicationOpenURLOptionsAnnotationKey])
    // Add any custom logic here.
    return handled
}

产生此构建错误：

The following build commands failed:
    CompileSwift normal x86_64 /Users/kevinchiang/jh-mobile/ios/JustHive/Appdelegate.swift
    CompileSwiftSources normal x86_64 com.apple.xcode.tools.swift.compiler
(2 failures)

我对Swift和Obj-C不熟悉，所以我认为我的Swift代码可能有问题。

在你的函数中你有参数选项的类型是(UIApplicationOpenURLOptionsKey & id)它不存在你应该在Swift中查找它的等价物application(_:open:options:)，你可以看到{{3}是一个包含多个元素的字典，以正确使用FB sdk，您必须使用与选项注释和选项源应用程序对应的键，以便您可以正确使用它。

所以回答你的问题应该改变下面的第二个功能。让我知道它是怎么回事。

func application(_ app: UIApplication, 
              open url: URL, 
               options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool{ 
    let handled: Bool = FBSDKApplicationDelegate.sharedInstance().application(applic‌ation, openURL: url, sourceApplication: options[.sourceApplication], annotation: options[.annotation])
    return handled 
}

您还可以简化上面删除变量句柄的代码，它将如下所示。

func application(_ app: UIApplication, 
              open url: URL, 
               options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool{ 

    return FBSDKApplicationDelegate.sharedInstance().application(applic‌ation, openURL: url, sourceApplication: options[.sourceApplication], annotation: options[.annotation])

}
