【中文标题】facebook登录电子邮件不会很快（没有任何解决方案吗？）【英文标题】：facebook login email not come swift ( Isn't there any solution ? ) 【发布时间】：2017-11-06 23:31:29 【问题描述】：你好，我需要一些帮助我一直在搜索这个主题的几个小时我尝试了很多东西但我做不到。
这是我的代码
let facebookReadPermissions = ["public_profile", "email"]
func getFBUserData()
if((FBSDKAccessToken.current()) != nil)
self.getFBUserDataSecondStep()
else
FBSDKLoginManager().logIn(withReadPermissions: self.facebookReadPermissions, from: self) (result, error) in
if error != nil
FBSDKLoginManager().logOut()
else if (result?.isCancelled)!
FBSDKLoginManager().logOut()
else
self.showLoadingAlert()
let grantedPermissions = result?.grantedPermissions.map( "\($0)" )
for permission in self.facebookReadPermissions
if (grantedPermissions?.contains(permission))!
print("permission: \(permission)")
// CONSOLE WRITING HERE LIKE THIS
// permission: public_profile
// permission: email
if (result?.grantedPermissions.contains("email"))!
print("result is: \(result?.description ?? "nil")")
// result is: <FBSDKLoginManagerLoginResult: 0x1c0441920> ( console )
self.getFBUserDataSecondStep()
else
FBSDKLoginManager().logOut()
func getFBUserDataSecondStep()
FBSDKGraphRequest(graphpath: "/me", parameters: ["fields": "id, name, first_name, last_name, email"]).start(completionHandler: (connection, result, error) -> Void in
if (error == nil)
if let dict = result as? Dictionary<String, Any>
print(result)
// COMING WITH LIKE THIS
//"first_name" = Esn;
//id = 10156020817443470;
//"last_name" = "\U00c7ak\U0131ralar";
//name = "Esn Banu\U015f \U00c7ak\U0131ralar";
//--// Where is email ?
var email = ""
var firstName = ""
var lastName = ""
var facebookId = ""
var facebookToken = ""
if let controlEmail = dict["email"]
email = controlEmail as! String
if let controlFirstName = dict["first_name"]
firstName = controlFirstName as! String
if let controlLastName = dict["last_name"]
lastName = controlLastName as! String
if let controlFacebookId = FBSDKAccessToken.current().userID
facebookId = controlFacebookId
if let controlFacebookToken = FBSDKAccessToken.current().tokenString
facebookToken = controlFacebookToken
loginWithFacebook(email: email, firstName: firstName, lastName: lastName, facebookId: facebookId, accessToken: facebookToken, finishedClosured: (state) in
if state
let mainPage = self.mainStoryBoard.instantiateViewController(withIdentifier: "SWRevealViewController")
self.removeLoadingAlert()
self.passPage(page: mainPage)
return
self.removeLoadingAlert()
self.alert(message: "Giris Basarisiz")
return
)
else
print(error?.localizedDescription)
)
我需要去获取人的电子邮件才能将用户注册到我的应用程序。但是无论我尝试什么，电子邮件都没有。我该如何解决这个问题，如果我尝试使用我的个人帐户没问题，但另一个用户可能会出现问题。
【问题讨论】：
也许用户没有授予电子邮件权限？也许他们没有经过验证的电子邮件？ 我尝试了很多用户，我认为这是不可能的 以及我尝试在 android 中编写完成的这个应用程序，并且同一用户在 android 中尝试它的结果是成功的 【参考方案1】： Note : This is in swift 4.0
//giving permission
func getpermission()
let fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
// fbLoginManager.loginBehavior = FBSDKLoginBehavior.web
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"))
self.getFBUserData()
fbLoginManager.logOut()
// Get all details from here
func getFBUserData()
var fbId : String = ""
var fbEmail : String = ""
var fbName : String = ""
var fbPickUrl : String = ""
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)
//everything works print the user data
print("Result111:\(String(describing: result)) "as Any)
let dict = result as! NSDictionary
print("FB Email1st:\(dict)")
fbId = dict["id"] as! String
fbName = dict["name"] as! String
fbEmail = dict["email"] as! String
//get user picture url from dictionary
fbPickUrl = (((dict["picture"] as? [String: Any])?["data"] as? [String:Any])?["url"] as? String)!
print("FB ID: \(fbId)\n FB Email:\(fbEmail) \n FbName:\(fbName) \n FBProfileUrl:\(fbPickUrl)\n")
)

【参考方案2】：let loginManager = FBSDKLoginManager()
loginManager.logIn(withReadPermissions: ["user_about_me", "email" , "user_birthday","user_hometown"], from: self) (loginResult, error) in
if error != nil
self.showalert(strMessage: (error?.localizedDescription)!)
else
if loginResult?.grantedPermissions == nil
self.showalert(strMessage: "Login Permissions not granted")
return
if (loginResult?.grantedPermissions.contains("email"))!
if (loginResult?.grantedPermissions.contains("user_birthday"))!
self.getFBUserData()
else
self.getFBUserData()
func getFBUserData()
FBSDKGraphRequest.init(graphPath: "me?fields=id,name,email,first_name,last_name,cover,picture.type(large),gender,birthday,hometown", parameters: nil).start(completionHandler: (connection , result , error ) in
if(error == nil)
DispatchQueue.main.async
let dictionary = result as! NSDictionary
print(dictionary)
print("Name : \(dictionary.value(forKey: "name")!)")
print("FB ID : \(dictionary.value(forKey: "id")!)")
self.FaceBookID = dictionary.value(forKey: "id") as? String
else
self.showalert(strMessage: "Somthig Went Wrong..!")
)
【讨论】：
电子邮件收不到 :( 我设置的facebook id和显示名称 CFBundleURLTypes 它是什么，我应该写什么？ 我检查了没问题 cfbundleurltypes 已经设置好了 "first_name" = Esn;性别=女性； ID = 10156022270488470； “姓氏” = “\U00c7ak\U0131ralar”； name = "Esn Banu\U015f\U00c7ak\U0131ralar";图片 = 数据 = "is_silhouette" = 0; url = "scontent.xx.fbcdn.net/v/t1.0-1/p200x200/…"; ; ;就这样来了以上是关于facebook登录电子邮件不会很快（没有任何解决方案吗？）的主要内容，如果未能解决你的问题，请参考以下文章
