I have read a lot of tutorials about getting information from Facebook, but I have failed so far. I just want to get username and profile picture from Facebook.
- (IBAction)login:(id)sender {
[FBSession openActiveSessionWithReadPermissions:@[@"email",@"user_location",@"user_birthday",@"user_hometown"]
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
switch (state) {
case FBSessionStateOpen:
[[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
if (error) {
NSLog(@"error:%@",error);
} else {
// retrive user's details at here as shown below
NSLog(@"FB user first name:%@",user.first_name);
NSLog(@"FB user last name:%@",user.last_name);
NSLog(@"FB user birthday:%@",user.birthday);
NSLog(@"FB user location:%@",user.location);
NSLog(@"FB user username:%@",user.username);
NSLog(@"FB user gender:%@",[user objectForKey:@"gender"]);
NSLog(@"email id:%@",[user objectForKey:@"email"]);
NSLog(@"location:%@", [NSString stringWithFormat:@"Location: %@\n\n",
user.location[@"name"]]);
}
}];
break;
case FBSessionStateClosed:
case FBSessionStateClosedLoginFailed:
[FBSession.activeSession closeAndClearTokenInformation];
break;
default:
break;
}
} ];
}
I used this code for get information, but I cannot get the any information. Can you help me about it? or Can you prefer a tutorial to read it? I have read tutorials on developer.facebook.com.
Thank you for your interest.
This is the simplest way I've found to get the user's profile picture.
[[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *FBuser, NSError *error) {
if (error) {
// Handle error
}
else {
NSString *userName = [FBuser name];
NSString *userImageURL = [NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=large", [FBuser objectID]];
}
}];
