Get profile picture for other Facebook users in iOS - ios

Question

I'm trying to get the profile image for a Facebook user using the Graph API in the Facebook SDK for iOS but the example code from the website does not work for me.
https://developers.facebook.com/docs/graph-api/reference/user/picture/
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:#"/123456789/picture"
parameters:nil
HTTPMethod:#"GET"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
// Insert your code here
}];
I get the following error in the console.
FBSDKLog: starting with Graph API v2.4, GET requests for //123456789/picture should contain an explicit "fields" parameter
From my understanding of the error message instead of parameters:nil I need to enter something like parameters:#{#"fields": #"id"} but whatever I try result in the completing handler is always nil. I don't know what to enter for the profile picture.
EDIT:
I'm looking to get the profile picture for other users.

Try This One:-
- (IBAction)btnFaceBook:(id)sender {
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login setLoginBehavior:FBSDKLoginBehaviorBrowser];
[login logInWithReadPermissions:#[#"public_profile",#"email"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if (error)
{
[[FBSDKLoginManager new]logOut];
} else if (result.isCancelled)
{
// Handle cancellations
}
else
{
if ([result.grantedPermissions containsObject:#"email"])
{
[self getDataFromFB];
}
}
}];
}
-(void)getDataFromFB
{
MBProgressHUD *hud=[MBProgressHUD showHUDAddedTo:self.view animated:true];
if ([FBSDKAccessToken currentAccessToken]) {
[[[FBSDKGraphRequest alloc] initWithGraphPath:#"me" parameters:[NSDictionary dictionaryWithObject:#"political,picture.width(500).height(500),id,email,first_name,last_name,gender,name" forKey:#"fields"]]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error)
{
if (!error && [result count] != 0)
{
[hud hideAnimated:true];
NSLog(#"%#", result);
}
else
{
[hud hideAnimated:true];
[self displayAlertMesage:#"Some error has been occure." title:#"Oops!"];
}
}];
}
}

You can use the following code for getting the data from the facebook login:-
-(void)getFacebookProfileInfos
{
FBSDKGraphRequest *requestMe = [[FBSDKGraphRequest alloc]initWithGraphPath:#"me" parameters:#{#"fields": #"id,email,name,birthday,first_name,last_name,gender,picture.type(large)"}];
FBSDKGraphRequestConnection *connection = [[FBSDKGraphRequestConnection alloc] init];
[connection addRequest:requestMe completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if(result)
{
dictUserData = [[NSDictionary alloc]init];
dictUserData=result;
}
}];
[connection start];
}
you will get all the data in the "dictUserData" dictionary and from that you will access the facebook profile in this way:-
UIImage * imgProfile = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#", dictUserData[#"picture"][#"data"][#"url"]]]]];
NSString * strImageData = [self imageToNSString:imgProfile];
