Facebook Graph API GET request - Should contain "fields" parameter (Swift, Facebook SDK v4.5.1)
IosXcodeFacebookSwiftFacebook Graph-ApiIos Problem Overview
My iOS app uses Facebook's Graph API Request during sign up to get user information, which worked fine prior to upgrading to Facebook's newest SDK. After upgrading, I'm getting a runtime error stating: "FBSDKLog: starting with Graph API v2.4, GET requests for /me should contain an explicit "fields" parameter".
Here is the code:
func requestFacebook() {
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
println("Error: \(error)")
}
else if error == nil
{
let birthday : NSString = (result.valueForKey("birthday") as? NSString)!
var currentDate = NSDate()
var birthdayFormatter = NSDateFormatter()
let userCalendar = NSCalendar.currentCalendar()
birthdayFormatter.dateFormat = "MM/DD/YYYY"
var birthdayNSDate = birthdayFormatter.dateFromString(birthday as String)
var userAge = self.calculateAge(birthdayNSDate!)
PFUser.currentUser()!["age"] = userAge
var facebookID: NSString = (result.valueForKey("id") as? NSString)!
var pictureURL = "https://graph.facebook.com/\(facebookID)/picture?type=large&return_ssl_resources=1"
var URLRequest = NSURL(string: pictureURL)
var URLRequestNeeded = NSURLRequest(URL: URLRequest!)
NSURLConnection.sendAsynchronousRequest(URLRequestNeeded, queue: NSOperationQueue.mainQueue(), completionHandler: {(response: NSURLResponse!,data: NSData!, error: NSError!) -> Void in
if error == nil {
var picture = PFFile(data: data)
PFUser.currentUser()!["picture"] = picture
PFUser.currentUser()!.saveInBackgroundWithBlock({ (success, error) -> Void in
if error == nil {
var userPicture:PFFile = PFUser.currentUser()!.valueForKey("picture") as! PFFile
userPicture.getDataInBackgroundWithBlock { (imageData, error) -> Void in
if error == nil {
self.meProfileImageView.image = UIImage(data: imageData!)
var userName:String = PFUser.currentUser()!.valueForKey("username") as! String
var userAge:Int = PFUser.currentUser()!.valueForKey("age") as! Int
self.meLabel.text = "\(userName), \(userAge)"
self.findFriends()
}
}
} else {
println(error)
}
})
}
else {
println("Error: \(error.localizedDescription)")
}
})
}
})
}
The error message is at the line:
let birthday : NSString = (result.valueForKey("birthday") as? NSString)!
This code ran perfectly fine before upgrading to Facebook's SDK v4.5.1, but I don't know what to change to make this work now. Huge thanks to anyone that can help me!

this line needs a parameters value that is NOT nil
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
I'll expand more, for example, and this is psuedo code of sorts:
so for ObjC it would be this, for example, so the the above would read the following:
parameters:@{@"fields": @"id, name"}
In swift it would be something similar
something like this:
parameters:["fields": "email"]
This is for just two fields, and again it's psuedo code, but you need to specify the parameters
UPDATE:
Im adding this update to show folks where you find the parameters for the fields as described above, here's a quick link:
Here's the Paramters field info (this should stay roughly static with FBSDK, some of this is "core" which means it won't really change that much, but I'll update whenever I can):
https://developers.facebook.com/docs/graph-api/reference/user
The format of the info below is the following, sort of, I just did this quickly:
"parameter" "type"
"description"
> id numeric string
>
> The id of this person's user account. This ID is unique to each app
> and cannot be used across different apps. Our upgrade guide provides
> more information about app-specific IDs
>
>
>
> about string
>
> The About Me section of this person's profile
>
> age_range AgeRange
>
> The age segment for this person expressed as a minimum and maximum
> age. For example, more than 18, less than 21.
>
>
>
> bio string
>
> The person's bio
>
> birthday string
>
> The person's birthday. This is a fixed format string, like MM/DD/YYYY.
> However, people can control who can see the year they were born
> separately from the month and day so this string can be only the year
> (YYYY) or the month + day (MM/DD)
>
>
> context UserContext
>
> Social context for this person
>
> currency Currency
>
> The person's local currency information
>
> devices list
Also, here's the current "Edge" stuff: The format for "Edge' stuff is this, roughly, I did this quickly:
"Edge"
"Description"
> favorite_requests > > Developers' favorite requests to the Graph API > > request_history > > Developers' Graph API request history > > accounts > > Facebook Pages this person administers/is an admin for > > achievements > > Achievements made in Facebook games > > adaccounts > > The advertising accounts to which this person has access > > adaccountgroups > > Ad account groups > > adcontracts > > The person's ad contracts > > admined_groups > > Groups the user admins > > adnetworkanalytics > > Insights data for the person's Audience Network apps > > albums > > The photo albums this person has created > > apprequests > > This person's pending requests from an app > > apprequestformerrecipients > > App requests > > books > > The books listed on this person's profile > > domains > > The domains the user admins > > events > > Events for this person.

Solution 2 - Ios
use "fields" as Key and then comma separate your values
let params = ["fields": "email, friends"]
Solution 3 - Ios
In Obj-C insert in the logInWithReadPermissions method:
parameters:@{@"fields": @"id, name, email"}
if you leave nil in parameters you only receive id and name in the result object, although you have set for example:
NSArray *permissionsArray = @[ @"email", @"public_profile"];
It´s not very clear in the documentation, hope it can helps.
Solution 4 - Ios
I had the same problem, but adding field options would generate a request error when fetching the user photo. I solved this problem by adding a simple parameters:@{@"fields": @""} to the code:
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:[NSString stringWithFormat:@"me/picture"]
parameters:@{@"fields": @""}
HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
id result,
NSError *error) {
if (!error) {
// success
} else {
// fail
}}
];
Solution 5 - Ios
In Swift, you can declare multiple parameters like this:
let graphRequest: FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "email, first_name, last_name, gender, picture"])
