Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_GGLContext", referenced from:
type metadata accessor for ObjectiveC.GGLContext in AppDelegate.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

它指出它在 AppDelegate.h 文件中有 undefined symbol 我无法解决它

这是我的 AppDelegate.swift

import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,GIDSignInDelegate{

    var window: UIWindow?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> (Bool,Bool) {
        //Override point for customization after application launch.
       // return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
        var configureError: NSError?
        GGLContext.sharedInstance().configureWithError(&configureError)
        assert(configureError == nil, "Error configuring Google services: \(configureError)")

        GIDSignIn.sharedInstance().delegate = self

        return (true,FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions))
    }

    //func application(application: UIApplication,
    //    didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> (Bool,Bool) {
            // Initialize sign-in

    // }


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

            return (FBSDKApplicationDelegate.sharedInstance().application(
                application,
                openURL: url,
                sourceApplication: sourceApplication,
                annotation: annotation), GIDSignIn.sharedInstance().handleURL(url,
                    sourceApplication: sourceApplication,
                    annotation: annotation))
    }

    func signIn(signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!,
        withError error: NSError!) {
            if (error == nil) {
                // Perform any operations on signed in user here.
                let userId = user.userID                  // For client-side use only!
                let idToken = user.authentication.idToken // Safe to send to the server
                let name = user.profile.name
                let email = user.profile.email                // ...
            } else {
                print("\(error.localizedDescription)")
            }
    }
    func signIn(signIn: GIDSignIn!, didDisconnectWithUser user:GIDGoogleUser!,
        withError error: NSError!) {
            // Perform any operations when the user disconnects from app here.
            // ...
    }
}

您必须链接 libGGLAnalytics.a 和 libGGLCore.a 才能使 GA 工作。

将其链接到您应用的目标构建阶段
