I have a profile picture which I am taking from a URL from facebook graph request that I am trying to make into a circular profile picture but it is appearing like this:
I don't want it to be pointing at the top, I just want a perfect circle.
This is my code:
#IBOutlet var imageURL: UIImageView!
func returnUserData()
{
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id,email,name,picture.width(50).height(50)"])
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
print("Error: \(error)")
}
else
{
print("fetched user: \(result)")
let userID : NSString = result.valueForKey("id") as! NSString
let userName : NSString = result.valueForKey("name") as! NSString
print("User Name is: \(userName)")
let userEmail : NSString = result.valueForKey("email") as! NSString
print("User Email is: \(userEmail)")
let facebookProfileUrl = "https://graph.facebook.com/\(userID)/picture?type=large"
print("\(facebookProfileUrl)")
let url = NSURL(string:facebookProfileUrl)
let data = NSData(contentsOfURL:url!)
if data == nil {
} else {
self.imageURL.layer.borderWidth=1.0
self.imageURL.layer.masksToBounds = false
self.imageURL.layer.borderColor = UIColor.whiteColor().CGColor
self.imageURL.layer.cornerRadius = 15
self.imageURL.layer.cornerRadius = self.imageURL.frame.size.height/2
self.imageURL.clipsToBounds = true
self.imageURL.image = UIImage(data:data!)
}
}
})
}
Apparently your input image isn't square. Crop the top and bottom (or extend the sides) to make it square, then the rest should work.

I am using interested in obtaining the following info from a user's fb profile :
email
name
profile picture link
age
To do so I use the following code:
let accessToken = FBSDKAccessToken.currentAccessToken()
let req = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"picture.redirect(false),email,name,gender,age_range,birthday"], tokenString: accessToken.tokenString, version: nil, HTTPMethod: "GET")
req.startWithCompletionHandler({ (connection, result, error : NSError!) -> Void in
if(error == nil)
{
print("result \(result)")
}
else
{
print("error \(error)")
}
}) }
This returns:
result {
"age_range" = {
min = 21;
};
email = "dedewdd#gmail.com";
gender = male;
id = xxxxxxxxxxxx;
name = "John Smith";
picture = {
data = {
"is_silhouette" = 0;
url = "https://scontent.xx.fbcdn.net/v/t1.0-1/p50x50/dwqdwddqwdwqdw";
};
};
}
The problem with this is that this image is 50X50 pixels, I would like to obtain a link to a larger image.
So I use Kingfisher to download the image but essentially the NSURL is the key to getting a larger image. IF this doesnt work, then try changing the "50x50" in the url to "250x250" and see if that works
if FBSDKAccessToken.currentAccessToken() != nil {
let userID = FBSDKAccessToken.currentAccessToken().userID
if(userID != nil) //should be != nil
{
print(userID)
}
let URL = NSURL(string: "http://graph.facebook.com/\(userID)/picture?type=large")!
profileImage.kf_setImageWithURL(URL)
}else{
}
}
Try this:
#IBAction func FacebookLogin(sender: AnyObject) {
var message = String()
if Reachability.isConnectedToNetwork() == true {
let loginView : FBSDKLoginManager = FBSDKLoginManager()
loginView.loginBehavior = FBSDKLoginBehavior.Web
if (FBSDKAccessToken .currentAccessToken() != nil) {
loginView.logOut()
}else{
loginView.logInWithReadPermissions(["email","public_profile"], fromViewController: self, handler: { (result:FBSDKLoginManagerLoginResult!, error:NSError!) in
if (error != nil){
print("Login Process Eroor!"+error.localizedDescription)
}else if result.isCancelled{
print("User cancled Login")
}else{
print("Login Success")
if result.grantedPermissions .contains("email"){
self.fetchUserInfo()
}else{
message = message.stringByAppendingString("Facebook email permission error")
WebService.ShowToastMessage(message, viewcontroller: self)
}
}
})
}
} else {
message = message.stringByAppendingString("Make sure your device is connected to the internet.")
WebService.ShowToastMessage(message, viewcontroller: self)
}
}
func fetchUserInfo() -> Void {
if (FBSDKAccessToken .currentAccessToken() != nil) {
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id,gender,birthday,email,name,picture.width(480).height(480)"])
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
print("Error: \(error.localizedDescription)")
}
else
{
print("fetched user: \(result)")
let id : NSString = result.valueForKey("id") as! String
let name:NSString = result.valueForKey("name") as! String
let gender:NSString = result.valueForKey("gender") as! String
let email:NSString = result.valueForKey("email") as! String
print("User ID is: \(id)")
print("User email is:\(email)")
print("User name is :\(name)")
print("User gender is :\(gender)")
}
})
}
}
According to the facebook docs
https://developers.facebook.com/docs/graph-api/reference/user/picture/
You can pass width and height of image,following are the list of params..
So you can try something like ..
[[[FBSDKGraphRequest alloc] initWithGraphPath:#"me" parameters:#{ #"fields" : #"id,name,picture.width(100).height(100)"}]startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
}]
Use this code for getting user id, name and profilepicture with one request : https://stackoverflow.com/a/45462114/1168602
Tested on xcode 8.3.3
I'm trying to fetch the user's fb profile pic but wasn't able to do so far. I'm trying to do something simple: the user log in with fb account and the app goes to another view where appears his name, email and profile picture. User's name and email are okay, but I can't get the picture!
The app is crashing with my actual code because apparently I'm unwrapping a nil optional value, but I don't know why it's nil.
My code:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id,email,name,picture.width(480).height(480)"])
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
print("Error: \(error)")
}
else
{
print("fetched user: \(result)")
let userName : NSString = result.valueForKey("name") as! NSString
print("User Name is: \(userName)")
let userEmail : NSString = result.valueForKey("email") as! NSString
print("User Email is: \(userEmail)")
let id = result.valueForKey("id") as! String
self.nameLabel.text = userName as String
self.emailLabel.text = userEmail as String
self.profilePic.image = self.getProfPic(id)
}
})
}
func getProfPic(fid: String) -> UIImage? {
if (fid != "") {
let imgURLString = "http://graph.facebook.com/" + fid + "/picture?type=large" //type=normal
let imgURL = NSURL(string: imgURLString)
let imageData = NSData(contentsOfURL: imgURL!)
let image = UIImage(data: imageData!) // CODE CRASHES IN HERE
return image
}
return nil
}
From your comments I understand that it crashes at the image assigning, you should be doing it with the conditional binding methodology of Swift (if let) in order to avoid unwrapping a nil optional value:
if let data = result["picture"]?["data"]
{
if let url = data["url"] as? String
{
profilePictureURL = url
}
}
Also, as you can see I am not using the valueForKey method.
My problem boils down to this: fetch a photo URL given a photo ID. Ultimately, I need to do this for all of the photos a user of my iOS app is tagged in. I am able to get the IDs of the photos with the code:
// Create request for user's Facebook data
let request = FBSDKGraphRequest(graphPath:"me", parameters:["fields": "photos"])
request.startWithCompletionHandler {
(connection, result, error) in
if error != nil { }
else if let userData = result as? [String:AnyObject] {
let userPhotos = userData["photos"]
}
}
In the returned user data, I have access to the ID of each photo. Now, I defined a function which should (ideally) return the URL of a photo given it's ID. However, I really do not know how to correctly call the Facebook Graph API. This is what I have (note: hardcoded photo ID).
// Create request for user's Facebook data
let request = FBSDKGraphRequest(graphPath:"/{photo-id}?id=xxxxxxxxxxxxxxxxx", parameters:["fields": "link"])
request.startWithCompletionHandler {
(connection, result, error) in
if error != nil { }
else if let userData = result as? [String:AnyObject] {
let link = userData["link"]
print(link)
}
}
I'm quite confident the the graphPath parameter is wildly wrong. I made some "intelligent" guesses based on this: https://developers.facebook.com/docs/graph-api/reference/photo/
Any help you could give me would be much appreciated. Thanks!
Ok here is a simple answer, thanks for the answer above #user2585945
import UIKit
class FacePhotosViewController: UIViewController{
#IBOutlet weak var imgTest: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
if (FBSDKAccessToken.currentAccessToken() != nil)
{
print("We are good!")
}
let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"photos,picture"])
graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in
if ((error) != nil)
{
// Process error
print("Error: \(error)")
}
else
{
print(result)
let resultdict = result.objectForKey("photos") as! NSDictionary
let data : NSArray = resultdict.objectForKey("data") as! NSArray
for i in 0..<data.count {
let valueDict : NSDictionary = data[i] as! NSDictionary
let id = valueDict.objectForKey("id") as! String
let created_time = valueDict.objectForKey("created_time") as! String
print("id: \(id) created_time: \(created_time) ")
}
}
})
let graphRequestPhoto : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "10156292340905363?type=large", parameters: ["fields":"picture, name, album, place"])
graphRequestPhoto.startWithCompletionHandler({ (connection, result, error) -> Void in
print(result)
if ((error) != nil)
{
// Process error
print("Error: \(error)")
}
else if let userData = result as? [String:AnyObject] {
let url = userData["picture"] as? String
print("link: \(url)")
let imgURL: NSURL! = NSURL(string: url!)
//lets' download profile photo
let session = NSURLSession.sharedSession()//session
let request: NSURLRequest = NSURLRequest(URL: imgURL!)//request
let dataTask = session.dataTaskWithRequest(request) { (data:NSData?, response:NSURLResponse?, error:NSError?) -> Void in //session calls the request
if let noerror = data {
dispatch_async(dispatch_get_main_queue()) {
let image = UIImage(data: noerror)
self.imgTest.image = image
}
}
else {
print("Error: \(error!.localizedDescription)", terminator: "")
}
}
dataTask.resume()
}
})
}
}
let requestPhotos = FBSDKGraphRequest(graphPath:id_num, parameters:["fields":"picture, name, album, place"])
Where id_num is the ID number of the Facebook photo. Very simple.
I have a log in system in my app swift 2.0 integrated with Facebook, I'm able to get some user informations and profile_picture.
I'm wondering how to get the cover Image from the User logged :
let requestParameters = ["fields": "id, email, first_name, last_name, name, gender, cover"]
let userDetails = FBSDKGraphRequest(graphPath: "me", parameters: requestParameters)
userDetails.startWithCompletionHandler { (connection, result, error:NSError!) -> Void in
if(error != nil)
{
print("\(error.localizedDescription)")
return
}
if(result != nil)
{
let userId:String = result["id"] as! String
let userFirstName:String? = result["first_name"] as? String
let userLastName:String? = result["last_name"] as? String
let userEmail:String? = result["email"] as? String
let userName:String? = result["name"] as? String
let userGender:String? = result["gender"] as? String
let userCover:UIImage? = result["cover"] as? UIImage
print(requestParameters)
print(userDetails)
print(userCover)
print("\(userEmail)")
let myUser:PFUser = PFUser.currentUser()!
// Save first name
if(userFirstName != nil)
{
myUser.setObject(userFirstName!, forKey: "firstNameColumn")
}
//Save last name
if(userLastName != nil)
{
myUser.setObject(userLastName!, forKey: "lastNameColumn")
}
// Save email address
if(userEmail != nil)
{
myUser.setObject(userEmail!, forKey: "email")
}
// Save email address
if(userGender != nil)
{
if (userGender == "male"){
myUser.setObject("Masculino", forKey: "genderColumn")
} else {
myUser.setObject("Feminino", forKey: "genderColumn")
}
}
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)) {
// Get Facebook profile picture
let userProfile = "https://graph.facebook.com/" + userId + "/picture?type=large"
let profilePictureUrl = NSURL(string: userProfile)
let profilePictureData = NSData(contentsOfURL: profilePictureUrl!)
if(profilePictureData != nil)
{
let profileFileObject = PFFile(data:profilePictureData!)
myUser.setObject(profileFileObject!, forKey: "photoUserColumn")
}
myUser.saveInBackgroundWithBlock({ (success:Bool, error:NSError?) -> Void in
if(success)
{
print("User details are now updated")
}
})
}
This code its not working just for the cover Image.
Any ideas?
Here's a working example using fb sdk in swift. I posted this answer in the other question as well but because this answer came up first for me on google I thought it'll be nice to put it here as well.
I needed to get the cover photo of a page so in the graphPath I used page id. This parameter can be easily changed to fit users / events / etc...
let request = FBSDKGraphRequest(graphPath: "\\(page.id)?fields=cover", parameters: [
"access_token": "your_access_token"
], HTTPMethod: "GET")
request.startWithCompletionHandler({(connection , result , error) in
if ((error) != nil) {
print("Error in fetching cover photo for \\(page.id): \(error)", terminator: "")
}
else {
if let data = result["cover"] as? NSDictionary {
self.fetchImageFromUrl(data["source"] as! String, cb: {(image: UIImage) -> Void in
//do something with image
})
}
})
func fetchImageFromUrl(url: String, cb: (UIImage) -> Void) {
let urlObj = NSURL(string: url)!
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)) {
let data = NSData(contentsOfURL: urlObj)
dispatch_async(dispatch_get_main_queue(), {
let image = UIImage(data: data!)!
cb(image)
});
}
}
P.S - I'm a newbie in swift / ios so this code might not be the best. Comments will be appreciated.
It can be useful.
let emailRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"email,name, id,cover"], tokenString: result?.token.tokenString, version: nil, httpMethod: "GET")
_ = emailRequest?.start(completionHandler: { (nil, resultParameters, error) in
if(error == nil) {
if let cover = (params?["cover"] as? NSDictionary)["source"]{
var coverUrl = cover as? String
}
}
})
I am not an expert in programming, but I modified a code to get the user profile picture from Facebook SDK. The problem is I am getting a Question Mark in the image (profilePicture.image). Can anyone tell me what is going on here?
Also, I am not sure what how to call this function to get image in viewController? At present I am directly adding profilePicture.image inside the function.
func getProfPic(fid: String) -> UIImage? {
if (fid != "") {
var imgURLString = "http://graph.facebook.com/" + fid + "/picture?type=large" //type=normal
var imgURL = NSURL(string: imgURLString)
var imageData = NSData(contentsOfURL: imgURL!)
var image = UIImage(data: imageData!)
profilePicture.image = image // Returned image is Question mark
return image
}
return nil
}
Create a dictionary :
class ViewController: UIViewController {
var dict : NSDictionary!
}
Fetching the data :
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){
self.dict = result as NSDictionary
println(self.dict)
NSLog(self.dict.objectForKey("picture")?.objectForKey("data")?.objectForKey("url") as String)
}
})
}
Output should be :
{
email = "ashishkakkad8#gmail.com";
"first_name" = Ashish;
id = 910855688971343;
"last_name" = Kakkad;
name = "Ashish Kakkad";
picture = {
data = {
"is_silhouette" = 0;
