问题
i have integrated Facebook sdk in Xcode 6 (with swift). During the login i request the public_profile permission:
FBSession.openActiveSessionWithReadPermissions(["public_profile"], allowLoginUI: true, completionHandler: {
...
...
So i request the user's information:
FBRequestConnection.startForMeWithCompletionHandler { (connection, user, error) -> Void in
...
...
Why the user object doesn't contain the profile picture? How can i get the user profile picture? It's not part of the public_profile?
I get the following information:
2015-01-25 01:25:18.858 Test[767:23804] {
"first_name" = xxx;
gender = xxx;
id = xxxxxxxxx;
"last_name" = xxxxxx;
link = "https://www.facebook.com/app_scoped_user_id/xxxxxxxxx/";
locale = "xxxxx";
name = "xxxxxxx xxxxxxx";
timezone = 1;
"updated_time" = "2013-12-21T18:45:29+0000";
verified = 1;
}
P.S: xxx for privacy
回答1:
The profile picture is in fact public and you can simply by adding the user id to Facebook's designated profile picture url address, ex:
var userID = user["id"] as NSString
var facebookProfileUrl = "http://graph.facebook.com/\(userID)/picture?type=large"
This particular url address should return the "large" version of the user's profile picture, but several more photo options are available in the docs.

If you want to get the picture in the same request as the rest of the users information you can do it all in one graph request. It's a little messy but it beats making another request.
A more Swift 3 approach
let request = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, email, picture.type(large)"])
let _ = request?.start(completionHandler: { (connection, result, error) in
guard let userInfo = result as? [String: Any] else { return } //handle the error
//The url is nested 3 layers deep into the result so it's pretty messy
if let imageURL = ((userInfo["picture"] as? [String: Any])?["data"] as? [String: Any])?["url"] as? String {
//Download image from imageURL
}
})
Swift 2
let request = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, email, picture.type(large)"])
request.startWithCompletionHandler({ (connection, result, error) in
let info = result as! NSDictionary
if let imageURL = info.valueForKey("picture")?.valueForKey("data")?.valueForKey("url") as? String {
//Download image from imageURL
}
})

With Facebook SDK 4.0, you can use:
Swift:
let pictureRequest = FBSDKGraphRequest(graphPath: "me/picture?type=large&redirect=false", parameters: nil)
pictureRequest.startWithCompletionHandler({
(connection, result, error: NSError!) -> Void in
if error == nil {
println("\(result)")
} else {
println("\(error)")
}
})
Objective-C:
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:[NSString stringWithFormat:@"me/picture?type=large&redirect=false"]
parameters:nil
HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
id result,
NSError *error) {
if (!error){
NSLog(@"result: %@",result);}
else {
NSLog(@"result: %@",[error description]);
}}];

Swift 4 approach :-
private func fetchUserData() {
let graphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id, email, name, picture.width(480).height(480)"])
graphRequest?.start(completionHandler: { (connection, result, error) in
if error != nil {
print("Error",error!.localizedDescription)
}
else{
print(result!)
let field = result! as? [String:Any]
self.userNameLabel.text = field!["name"] as? String
if let imageURL = ((field!["picture"] as? [String: Any])?["data"] as? [String: Any])?["url"] as? String {
print(imageURL)
let url = URL(string: imageURL)
let data = NSData(contentsOf: url!)
let image = UIImage(data: data! as Data)
self.profileImageView.image = image
}
}
})
}

if you want get bigger picture , just replace "type = large" to width=XX&height=XX
but the biggest picture you can get is original picture
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:@"me/picture?width=1080&height=1080&redirect=false"
parameters:nil
HTTPMethod:@"GET"];
[request startWithCompletionHandler:^(
FBSDKGraphRequestConnection *connection,
id result,
NSError *error) {
if (!error)
{
NSLog(@"result = %@",result);
NSDictionary *dictionary = (NSDictionary *)result;
NSDictionary *data = [dictionary objectForKey:@"data"];
NSString *photoUrl = (NSString *)[data objectForKey:@"url"];
}
else
{
NSLog(@"result = %@",[error description]); }
}];

@Brandon Gao solution gave me a 200X200 thumbnail...
To get a bigger size I used FBSDKProfile to get a path with size, that is also more modular and not hard-coded (although I did have to type in the graph.facebook.com part...)
let size = CGSize(width: 1080, height: 1080)
let path = FBSDKProfile.currentProfile().imagePathForPictureMode(.Normal, size: size)
let url = "https://graph.facebook.com/\(path)"
Alamofire.request(.GET, url, parameters: nil, encoding: ParameterEncoding.URL).response {
(request, response, data, error) -> Void in
if let imageData = data as? NSData,
let image = UIImage(data: imageData) {
self.buttonImage.setImage(image, forState: .Normal)
}
}
Somehow I didn't get a 1080X1080 image though, FB gave me a 1117X1117... :\

For swift this is the simple way for get the url of the photo with and specific size:
let params: [NSObject : AnyObject] = ["redirect": false, "height": 800, "width": 800, "type": "large"]
let pictureRequest = FBSDKGraphRequest(graphPath: "me/picture", parameters: params, HTTPMethod: "GET")
pictureRequest.startWithCompletionHandler({
(connection, result, error: NSError!) -> Void in
if error == nil {
print("\(result)")
let dictionary = result as? NSDictionary
let data = dictionary?.objectForKey("data")
let urlPic = (data?.objectForKey("url"))! as! String
print(urlPic)
} else {
print("\(error)")
}
})
}

you can use this code For Swift 3.0 to get the user information
func getFbId(){
if(FBSDKAccessToken.current() != nil){
FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id,name , first_name, last_name , email,picture.type(large)"]).start(completionHandler: { (connection, result, error) in
guard let Info = result as? [String: Any] else { return }
if let imageURL = ((Info["picture"] as? [String: Any])?["data"] as? [String: Any])?["url"] as? String {
//Download image from imageURL
}
if(error == nil){
print("result")
}
})
}
}

Then set your user's picture profile to ImageView.
let facebookId = "xxxxxxx"
let facebookProfile: String = "http://graph.facebook.com/\(facebookId)/picture?type=large"
let url: URL = URL(string: facebookProfile)!
myImageView.kf.setImage(with: url)
