FacebookLoginsDK 4 Apple Mach-O链接器错误

Question

我正在尝试使用Swift 3将FacebookLogin SDK 4集成到我的iOS应用中。我添加了以下3个框架：Bolts，FBSDKCoreKit和FBSDKLoginKit。我根据Facebook文档更改了Info.plist，创建了桥接标头文件，并将其路径添加到我的构建设置中。

一旦我在AppDelegate.swift文件中添加以下行，我就会得到：

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

我在此处尝试了：Apple Mach-O链接器编译设备时错误他们都没有帮助（除非我错过了什么）。还有其他人有类似的问题吗？请帮助。

Answer 1

您是否在应用程序委托中添加了此方法

   func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any])
        -> Bool {
            return FBSDKApplicationDelegate.sharedInstance().application(application, open: url as URL!, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String, annotation: [:])
}

此外，这是Willresignactive方法

func applicationWillResignActive(_ application: UIApplication)
{
     FBSDKAppEvents.activateApp()
}
