How to get user's facebook profile pic via fbconnect in my app iPhone?

Answer 1

Try look deeper through http://developers.facebook.com/docs/api. Here is a link to userpic:

http://graph.facebook.com/000000000/picture

Where 000000000 is an id of user logged.

UPDATE by Michael Gaylord: You can also append the type to the request to get different sized images. So your request will look something like: http://graph.facebook.com/00000000/picture?type=large for a large image. Other options are small, normal and square.

Answer 2

I think the most simple way is this:

NSString *fbuid = @"1234567890";
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?", fbuid]];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *profilePic = [[[UIImage alloc] initWithData:data] autorelease];

Answer 3

Here use these delegate methods to get the picture of user.

When you create session you will get the delegate method called didLogin

- (void)session:(FBSession*)session didLogin:(FBUID)uid {

    isLoginSuccessful = TRUE;
    if(isLoginCanceled == FALSE) {
        [self fetchUserDetails];
    }
}

- (void)sessionDidNotLogin:(FBSession*)session {
    isLoginSuccessful = FALSE;
    isLoginCanceled = TRUE;
}

- (void)sessionDidLogout:(FBSession*)session {
    isLoginSuccessful = FALSE;
    isLoginCanceled = TRUE;
}

- (void)fetchUserDetails {

    NSString* fql = [NSString stringWithFormat:
                     @"select name,sex,pic from user where uid == %lld", _session.uid];

    NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:@"query"];
    [[FBRequest requestWithDelegate:self] call:@"facebook.fql.query" params:params];
}

after calling the method requestWithDelegate you'll get response in this method if succeed

- (void)request:(FBRequest*)request didLoad:(id)result {
    if ([request.method isEqualToString:@"facebook.fql.query"]) {
        NSArray* users = result;
        NSDictionary* user = [users objectAtIndex:0];
                NSLog(@"User Details %@",user);
        if(fbUserDetails == nil) {
            self.fbUserDetails = [[NSDictionary alloc] initWithDictionary:user];
        }
        if(isLoginSuccessful) {
            NSString *fbUid = [NSString stringWithFormat:@"%lld",_session.uid];
            self.FBUserID = fbUid;
            [_delegate loggedInFaceBookSuccessfully:fbUid];
        }

    }
}

You'll get all the details in json format you can see in GDB
