iOS Facebook登录崩溃

我正在使用FBSDK 4.32.0，它在iOS 11.3版本中不断崩溃，请帮助我，我尝试过不同的设备，它们有不同的iOS版本，不幸的是，所有的版本都崩溃了，下面是我的代码

    @IBAction func didTapLogainAction(_ sender: Any) {
    let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
    fbLoginManager.logIn(withReadPermissions: ["email"], from: self) { (result, error) in
        if (error == nil){
            let fbloginresult : FBSDKLoginManagerLoginResult = result!
            if fbloginresult.grantedPermissions != nil {
                if(fbloginresult.grantedPermissions.contains("email")) {
                    if((FBSDKAccessToken.current()) != nil){
                        FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).start(completionHandler: { (connection, result, error) -> Void in
                            if (error == nil){
                                let dict = result as! [String : AnyObject]
                                let alrt = UIAlertController(title: "Success", message: "Logged in", preferredStyle: .alert)
                                let alrtDon = UIAlertAction(title: "Done", style: .default, handler: {(alert: UIAlertAction!) in
                                    print("Perfect")
                                })
                                alrt.addAction(alrtDon)
                                self.present(alrt, animated: true, completion: nil)
                                FBSDKLoginManager().logOut()
                                self.LoginViaFacebook(dict: dict as NSDictionary)
                            }
                        })
                    }
                }
            }
        }
    }
}

试试这个代码。这对我有用。更多信息

导入FacebookLogin
导入FacebookCore
导入FBSDKCoreKit
//马克：用Facebook登录
func loginWithFacebook（controllerName:UIViewController，完成：@escaping（uIsAccess:Bool，uResponse:Any，uCheckInternet:String）->Void）
{
/*这里有三件事是必须的
1.FacebookAppId
2.FaceBook显示名称
3.将URL架构添加到infor plist文件中。
CfBundleUrlTypeCfBundleTypeRoleEditorCfBundleUrlSchemes
-----------------------FB123123---------------------
*/
FBSDKSettings.setAppID（FacebookAppID）
FBSDKSettings.setDisplayName（FacebookDisplayName）
让loginManager=loginManager（）
登录（readPermissions:[.publicProfile，.email]，viewController:controllerName）{（loginResult）在
如果loginResult.self！=nil{
let request=GraphRequest（graphPath:/me），参数：[“字段”：“id、电子邮件、姓名、姓氏、图片、年龄范围、性别、区域设置、链接、时区、更新的时间、验证的地址、生日”]、accessToken:accessToken.current、httpMethod:.GET、apiVersion:FacebookCore.GraphaDriversion.defaultVersion）
request.start{（响应、结果）在
打印（结果）
切换结果{
成功案例（let value）：
如果value.dictionaryValue！=nil{
完成（true，value.dictionaryValue！，“”）
}否则
{
完成（假，“，”）
}
案例。失败（let错误）：
完成（false，“\（错误）”，“”）
}
}
}否则
{
完成（假，“，”）
}
}
}

在“AppDelegate”文件中，替换函数

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
    // your code here
    return true
}

借

它适合我。

在appdelegate复制中，首先粘贴此代码

AppDelegate.swift File

 import FBSDKCoreKit
 import FBSDKLoginKit


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



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

现在将其粘贴到Viewcontroller上，并链接到按钮操作

@IBAction func loginWithFB(_ sender: Any) {

//        let loginManager = FBSDKLoginManager()
//
//        loginManager.logIn(withReadPermissions:["public_profile","user_friends","email"], from: self) {
//            loginResult,error in
//
//            print("completion handler called")
//        }
        let loginManager = FBSDKLoginManager()
        loginManager.logIn(withReadPermissions: [ "public_profile" ,"email" ], from: self) { loginResult,error  in

            if error != nil {
                print("error")
            }else if(loginResult?.isCancelled)!{
                print("result cancelled")
            }else {
                print("success")

                FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, email"]).start(completionHandler: { (connection, result, error) -> Void in
                    if (error == nil){
                        let fbDetails = result as! NSDictionary
                        print(fbDetails)
                    }else{
                        print(error?.localizedDescription ?? "Not found")
                    }
                })

            }
        }
    }

如果您遇到问题，请仍然告诉我

是否显示与此相关的碰撞报告？
