I am using Xcode 10, Swift 5 and I am trying to set a UITextField to just the user name I retrieved from Facebook. I have successfully retrieved the ID, Email, and Name in result but when I sent result to the text field is includes all three fields. I just want the name.
func getUserProfile() {
let req = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"name"], tokenString: accessToken?.tokenString, version: nil, httpMethod: "GET")
req?.start(completionHandler: { (connection, result, error : Error!) -> Void in
if(error == nil)
{
print("\(String(describing: result))")
self.FBUserName.text = "name \(String(describing: result))"
}
else
{
print("error \(String(describing: error))")
}
})
}
You can cast result to [String : Any], like so
if error != nil {
print("Error: \(error!.localizedDescription)")
} else if let result = result as? [String : Any] {
self.FBUserName.text = result["name"] as! String
}
Here is my working request
let graphRequest: FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "email,name"])
graphRequest.start(completionHandler: { [weak self] (connection, result, error) -> Void in
if error != nil {
print("Error: \(error!.localizedDescription)")
} else if let result = result as? [String : Any], let strongSelf = self {
strongSelf.txtName.text = (result["name"] as! String)
strongSelf.txtEmail.text = (result["email"] as! String)
}
})

Why can't I get user mail id for Facebook? I have attached my code below. I have doubt in login and registration using API
func getFacebookUserInfo() {
if(FBSDKAccessToken.current() != nil)
{
//print permissions, such as public_profile
print(FBSDKAccessToken.current().permissions)
let graphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields" : "id, first_name, last_name, email"])
let connection = FBSDKGraphRequestConnection()
connection.add(graphRequest, completionHandler: { (connection, result, error) -> Void in
let data = result as! [String : AnyObject]
self.firstnameLabel.text = data["first_name"] as? String
self.lastnameLabel.text = data["last_name"] as? String
guard let result = result as? NSDictionary else{ return }
let email = result["email"] as? String
self.googleemail = email!
let FBid = data["id"] as? String
let url = NSURL(string: "https://graph.facebook.com/\(FBid)/picture?type=large&return_ssl_resources=1")
self.imageView.image = UIImage(data: NSData(contentsOf: url! as URL)! as Data)
self.validateUserData()
})
connection.start()
}
}
facebook button click
#IBAction func btnFacebookClick(_ sender: Any)
{
// GeneralClass.startProgress()
loginManager.logIn(readPermissions: [ ReadPermission.publicProfile,ReadPermission.email], viewController: self) { (loginResult) in
switch loginResult {
case .failed(let error):
self.loginManager.logOut()
print(error)
case .cancelled:
self.loginManager.logOut()
print("User cancelled login.")
case .success(let grantedPermissions, let declinedPermissions, let accessToken):
print(grantedPermissions)
print(declinedPermissions)
print("Logged in!")
self.getFBUserData(accessToken: accessToken)
}
}
}
get data
func getFBUserData(accessToken: AccessToken)
{
let request = GraphRequest(graphPath: "me",
parameters: ["fields" : "first_name,middle_name,last_name,name,link,email,id,picture" as AnyObject],
accessToken:accessToken,
httpMethod: .GET)
request.start { (httpResponse, result) in
switch result {
case .success(let response):
let responseDictionary = response.dictionaryValue
print("USER DATA:---\(responseDictionary! as NSDictionary))")
let dicData = responseDictionary! as NSDictionary
if ((dicData["email"]) != nil) {
let email = dicData["email"] as! String
let user_firstName = dicData["first_name"] as! String
let imageUrl = (((dicData["picture"] as! NSDictionary)[KEY_DATA] as! NSDictionary)["url"] as! String)
}
case .failed(let error):
self.loginManager.logOut()
print(error)
}
}
}
Seems like the email value is nil. Set nil checking before assigning the value.
if let email = result["email"] as? String {
self.googleemail = email!
}
Hope this will help.
Hey guys i am struggling to resolve this error actually i am trying to send these 4 strings and one picture to firebase and this was working fine until this error came up.
guard let email = emailTextField.text, let password = passwordTextField.text, let name = nameTextField.text else {
print("Form is not valid")
return
}
Auth.auth().createUser(withEmail: email, password: password, completion: { (user:User?, error) in
if error != nil {
print(error!)
return
}
guard let uid = user?.uid else {
return
}
//successfully authenticated user
let imageName = UUID().uuidString
let storageRef = Storage.storage().reference().child("profile_images").child("\(imageName).jpg")
if let profileImage = self.profileImageView.image, let uploadData = UIImageJPEGRepresentation(profileImage, 0.1) {
// if let uploadData = UIImagePNGRepresentation(self.profileImageView.image!) {
storageRef.putData(uploadData, metadata: nil, completion: { (metadata, error) in
if error != nil {
print(error!)
return
}
if let profileImageUrl = metadata?.downloadURL()?.absoluteString {
let values = ["name": name, "email": email, "profileImageUrl": profileImageUrl]
self.registerUserIntoDatabaseWithUID(uid, values: values as [String : AnyObject])
}
})
}
})
}
fileprivate func registerUserIntoDatabaseWithUID(_ uid: String, values: [String: AnyObject]) {
let ref = Database.database().reference()
let usersReference = ref.child("users").child(uid)
usersReference.updateChildValues(values, withCompletionBlock: { (err, ref) in
if err != nil {
print(err!)
return
}
If you write a type of user parameter (user: User?) you also have to write the types of other parameters (error: Error?)
Auth.auth().createUser(withEmail: email, password: password) { (user: User?, error: Error?)
in ...
}
Also you may write by this way:
Auth.auth().createUser(withEmail: email, password: password) { user, error in
...
}
I'm trying to store facebook user data into firebase database but I keep getting the error "Cannot convert Any? to expected type String"
((FBSDKAccessToken.current()) != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, picture.type(large), email"]).start(completionHandler: { (connection, result, error) -> Void in
if (error == nil && result != nil) {
guard let fbData = result as? [String:Any] else { return }
let fbid = fbData["id"]
let name = fbData["name"]
self.ref.child("users").child(fbid).setValue([
"id": fbid,
"name": name
])
}
})
I also want to store the picture url into the database. How can I do this?
Using Facebook IOS Swift SDK and Firebase
Try my I implement this function. This is from the production app and it works well for us. I also recommend uploading profile image in Firebase storage or other storage, because after a while the profile image url is not valid.
class func getAllFacebookData(success: ((_ result: [String : Any]) -> Void)?, fail: ((_ error: Error) -> Void)?) {
guard !isGetDataFromFacebook else { return }
DispatchQueue.global(qos: .background).async {

req.start { (connection, result, error) in
if error == nil {
guard let _result = result as? [String : Any] else { return }
let _picture = _result["picture"] as? [String : Any]
let _pictureData = _picture?["data"] as? [String : Any]
let _isSilhouette = _pictureData?["is_silhouette"] as? Bool
let userPref = UserDefaults.standard
userPref.set(_isSilhouette, forKey: "UserHasSilhouetteImage")
userPref.synchronize()
debugPrint("facebook result", _result)
isGetDataFromFacebook = true
syncUserInfoInDatabase(_result)
success?(_result)
} else {
debugPrint("request", error!)
fail?(error!)
}
}
}
}
fileprivate class func syncUserInfoInDatabase(_ userInfo: [String : Any]) {
let realmManager = RealmManager()
guard let currentUser = realmManager.getCurrentUser() else { return }
guard let userInfoModel = createUserInfoModel(userInfo) else { return }
do {
let realm = try Realm()
try realm.write {
currentUser.info = userInfoModel
}
} catch {
debugPrint("realm syncUserInfoInDatabase error", error.localizedDescription)
}
savePhoto(userInfo)
let firebaseDatabaseGeneralManager = FirebaseDatabaseGeneralManager()
firebaseDatabaseGeneralManager.updateCurrentUser(success: nil, fail: nil)
// crete a personal settings
let firUserSettingsDatabaseManager = FIRUserSettingsDatabaseManager()
firUserSettingsDatabaseManager.createStartPeopleFilterSettings(success: nil, fail: nil)
let userSearchLocationModel = UserSearchLocationModel()
userSearchLocationModel.userID = currentUser.id

I am rewriting my graph requests with the latest Swift3. I am following the guide found here - https://developers.facebook.com/docs/swift/graph.
fileprivate struct UserProfileRequest: GraphRequestProtocol {
struct Response: GraphResponseProtocol {
init(rawResponse: Any?) {
// Decode JSON into other properties
}
}
let graphPath: String = "me"
let parameters: [String: Any]? = ["fields": "email"]
let accessToken: AccessToken? = AccessToken.current
let httpMethod: GraphRequestHTTPMethod = .GET
let apiVersion: GraphAPIVersion = .defaultVersion
}
fileprivate func returnUserData() {
let connection = GraphRequestConnection()
connection.add(UserProfileRequest()) {
(response: HTTPURLResponse?, result: GraphRequestResult<UserProfileRequest.Response>) in
// Process
}
connection.start()
However, I am getting this error in the connection.add method:
Type ViewController.UserProfileRequest.Response does not conform to protocol GraphRequestProtocol.
I can't seem to figure this out what to change here. It seems like the developer guide is not up to date on Swift3, but I am not sure that is the issue.
Is anyone able to see what is wrong here?
Thanks.
Browsing on the github issues, i found a solution.
https://github.com/facebook/facebook-sdk-swift/issues/63
Facebook documentation for Swift 3.0 and SDK 0.2.0 is not yet updated.
This works for me:
let params = ["fields" : "email, name"]
let graphRequest = GraphRequest(graphPath: "me", parameters: params)
graphRequest.start {
(urlResponse, requestResult) in
switch requestResult {
case .failed(let error):
print("error in graph request:", error)
break
case .success(let graphResponse):
if let responseDictionary = graphResponse.dictionaryValue {
print(responseDictionary)
print(responseDictionary["name"])
print(responseDictionary["email"])
}
}
}
enjoy.
This code works for me, first I make a login with the correct permissions, then I build the GraphRequest for get the user information.
let login: FBSDKLoginManager = FBSDKLoginManager()
// Make login and request permissions
login.logIn(withReadPermissions: ["email", "public_profile"], from: self, handler: {(result, error) -> Void in
if error != nil {
// Handle Error
NSLog("Process error")
} else if (result?.isCancelled)! {
// If process is cancel
NSLog("Cancelled")
}
else {
// Parameters for Graph Request without image
let parameters = ["fields": "email, name"]
// Parameters for Graph Request with image
let parameters = ["fields": "email, name, picture.type(large)"]
FBSDKGraphRequest(graphPath: "me", parameters: parameters).start {(connection, result, error) -> Void in
if error != nil {
NSLog(error.debugDescription)
return
}
// Result
print("Result: \(result)")
// Handle vars
if let result = result as? [String:String],
let email: String = result["email"],
let fbId: String = result["id"],
let name: String = result["name"] as? String,
// Add this lines for get image
let picture: NSDictionary = result["picture"] as? NSDictionary,
let data: NSDictionary = picture["data"] as? NSDictionary,
let url: String = data["url"] as? String {
print("Email: \(email)")
print("fbID: \(fbId)")
print("Name: \(name)")
print("URL Picture: \(url)")
}
}
}
})
Here is my code like. I use Xcode 8, Swift 3 and it works fine for me.
let parameters = ["fields": "email, id, name"]
let graphRequest = FBSDKGraphRequest(graphPath: "me", parameters: parameters)
_ = graphRequest?.start { [weak self] connection, result, error in
// If something went wrong, we're logged out
if (error != nil) {
// Clear email, but ignore error for now
return
}
// Transform to dictionary first
if let result = result as? [String: Any] {
// Got the email; send it to Lucid's server
guard let email = result["email"] as? String else {
// No email? Fail the login
return
}
guard let username = result["name"] as? String else {
// No username? Fail the login
return
}
guard let userId = result["id"] as? String else {
// No userId? Fail the login
return
}
}
} // End of graph request
Your UserProfileRequest should look like this:
fileprivate struct UserProfileRequest: GraphResponseProtocol {
fileprivate let rawResponse: Any?
public init(rawResponse: Any?) {
self.rawResponse = rawResponse
}
public var dictionaryValue: [String : Any]? {
return rawResponse as? [String : Any]
}
public var arrayValue: [Any]? {
return rawResponse as? [Any]
}
public var stringValue: String? {
return rawResponse as? String
}
}
