是否要为facebook登录创建自定义按钮？这可能会帮助您： 如果你愿意，你可以用swift转换

对于swift，您可以将此代码与任何自定义按钮一起使用：

@IBAction func loginFacebookAction(sender: AnyObject) {
    GAnalytics.registerClick("Login Facebook", screen: self.className)
    let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
    fbLoginManager.logInWithReadPermissions(["email"], fromViewController: self) { (result, error) -> Void in
        if (error == nil){
            let fbloginresult : FBSDKLoginManagerLoginResult = result
            if(fbloginresult.grantedPermissions.contains("email"))
            {
                self.getFBUserData()
            }
        }
    }
}

func getFBUserData(){
    if((FBSDKAccessToken.currentAccessToken()) != nil){
        FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, picture.type(large), email"]).startWithCompletionHandler({ (connection, result, error) -> Void in
            if (error == nil){
                print(result)
            }
        })
    }
}
