Getting Facebook username for iOS - iphone

I'm using the following to get the Facebook username:
[facebook requestWithGraphPath:#"me" andDelegate:facebook];
from my understanding I then have to use something like the following request to
- (void)request:(FBRequest *)request didLoad:(id)result {
NSLog(#"Result: %#", result);
NSDictionary *userInfo = (NSDictionary *)result;
userName = [userInfo objectForKey:#"name"];
fb_id = [userInfo objectForKey:#"id"];
}
my question is how do I call this request method from another method?
thanks for any help

check my function below to fetch user data id,pic and name
- (void)fetchUserDetails {
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"SELECT uid, name, pic FROM user WHERE uid=me()", #"query",nil];
[fb requestWithMethodName:#"fql.query"
andParams:params
andHttpMethod:#"POST"
andDelegate:self];
}
and in the delegate method you will log the name like this
- (void)request:(FBRequest *)request didLoad:(id)result
{
if ([result isKindOfClass:[NSArray class]] && [result count]>0) {
result = [result objectAtIndex:0];
}
if ([result objectForKey:#"name"])
NSString *userName = [result objectForKey:#"name"];
NSLog(#"%#",userName);
}

How to tag friends in your Facebook wall post...?

I am trying to tag some of my friends in my wall post and I am sending the following parameters but this posts to my wall the FB ids I provide do not get attached to the post...
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"Test 2 ",#"message",
#"100004311843201 , 1039844409", #"to",
#"http://www.google.com", #"link",
#"Test", #"name",
nil];
[self.appDelegate.facebook requestWithGraphPath:#"me/feed" andParams:params andHttpMethod:#"POST" andDelegate:self];
Any help is appreciated...
To tag a friend in ur fb status ..you need "facebook id" of your friend by using FBFriendPickerViewController and "place id" using FBPlacePickerViewController.
Following code will help you.
NSString *apiPath = nil;
apiPath = #"me/feed";
if(![self.selectedPlaceID isEqualToString:#""]) {
[params setObject:_selectedPlaceID forKey:#"place"];
}
NSString *tag = nil;
if(mSelectedFriends != nil){
for (NSDictionary *user in mSelectedFriends) {
tag = [[NSString alloc] initWithFormat:#"%#",[user objectForKey:#"id"] ];
[tags addObject:tag];
}
NSString *friendIdsSeparation=[tags componentsJoinedByString:#","];
NSString *friendIds = [[NSString alloc] initWithFormat:#"[%#]",friendIdsSeparation ];
[params setObject:friendIds forKey:#"tags"];
}
FBRequest *request = [[[FBRequest alloc] initWithSession:_fbSession graphPath:apiPath parameters:params HTTPMethod:#"POST"] autorelease];
[request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
[SVProgressHUD dismiss];
if (error) {
NSLog(#"Error ===== %#",error.description);
if (_delegate != nil) {
[_delegate facebookConnectFail:error requestType:FBRequestTypePostOnWall];
}else{
NSLog(#"Error ===== %#",error.description);
}
}else{
if (_delegate != nil) {
[_delegate faceboookConnectSuccess:self requestType:FBRequestTypePostOnWall];
}
}

How to attach data to Facebook app request on the iPhone?

I'm working on 'deep linking' a Facebook request into my iOS app. A Facebook app is setup and seems to work as I can send a request to a friend, the request badge appears in the friend's Facebook, and clicking on the request launches my app (all on the iPhone).
However, so far I could not pass any data with the request, which I want to use when my app launched from the Facebook app with the request.
I use the following call:
-(void) fbRequestActionWithMessage: (NSString *) message andLink: (NSString *) link
{
NSDictionary *requestData = [NSDictionary dictionaryWithObjectsAndKeys:
#"data1", #"key1",
#"data2", #"key2",
nil];
NSString *requestDataString = [requestData JSONRepresentation];
NSMutableDictionary* params = [NSMutableDictionary
dictionaryWithObjectsAndKeys:
message, #"message",
#"Check this out", #"notification_text",
link, #"link",
requestDataString, #"data",
nil];
[facebook dialog:#"apprequests" andParams:params andDelegate:self];
}
Neither the "data" nor the "link" values in the params dictionary seem to have any effect. Ideally, when my app is launched from this request, I would get back the "data" or the "link" values. Can this be done?
I could not find any Facebook docs about the structure of params dictionary - is there a list of supported keys and their effect?
The "link" parameter and "notification_text" is not supported in iOS but you should be able to pass in data and get it back.
Example, passing in data:
FBSBJSON *jsonWriter = [FBSBJSON new];
NSDictionary *requestData = [NSDictionary dictionaryWithObjectsAndKeys:
#"data1", #"key1",
#"data2", #"key2",
nil];
NSString *requestDataString = [jsonWriter stringWithObject:requestData];
NSMutableDictionary* params =
[NSMutableDictionary dictionaryWithObjectsAndKeys:
message, #"message",
requestDataString, #"data",
nil];
[facebook dialog:#"apprequests"
andParams:params
andDelegate:self];
Example, reading it back:
....
#property (nonatomic, retain) NSURL *openedURL;
....
#synthesize openedURL = _openedURL;
....
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
self.openedURL = url;
return [FBSession.activeSession handleOpenURL:url];
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
[FBSession.activeSession handleDidBecomeActive];
if (FBSession.activeSession.isOpen) {
[self checkIncomingNotification];
}
}
- (void) notificationGet:(NSString *)requestid {
[FBRequestConnection startWithGraphPath:requestid
completionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
if (!error) {
NSString *title;
NSString *message;
if ([result objectForKey:#"data"]) {
// Process data in request
FBSBJSON *jsonParser = [FBSBJSON new];
NSDictionary *requestData =
[jsonParser
objectWithString:[result objectForKey:#"data"]];
[NSString stringWithFormat:#"Badge: %#, Karma: %#",
NSString *data1 = [requestData objectForKey:#"key1"];
NSString *data2 = [requestData objectForKey:#"key2"];
}
}
}];
}
- (void) checkIncomingNotification {
if (self.openedURL) {
NSString *query = [self.openedURL fragment];
if (!query) {
query = [self.openedURL query];
}
NSDictionary *params = [self parseURLParams:query];
// Check target URL exists
NSString *targetURLString = [params valueForKey:#"target_url"];
if (targetURLString) {
NSURL *targetURL = [NSURL URLWithString:targetURLString];
NSDictionary *targetParams = [self parseURLParams:[targetURL query]];
NSString *ref = [targetParams valueForKey:#"ref"];
// Check for the ref parameter to check if this is one of
// our incoming news feed link, otherwise it can be an
// an attribution link
if ([ref isEqualToString:#"notif"]) {
// Get the request id
NSString *requestIDParam = [targetParams
objectForKey:#"request_ids"];
NSArray *requestIDs = [requestIDParam
componentsSeparatedByString:#","];
// Get the request data from a Graph API call to the
// request id endpoint
[self notificationGet:[requestIDs objectAtIndex:0]];
}
}
// Clean out to avoid duplicate calls
self.openedURL = nil;
}
}

Facebook iOS SDK not returning user email

I am trying to get access to some user's info, including email. For this purpose, I use the Graph API to call this method:
[facebook requestWithGraphPath:#"me" andDelegate:self];
It returns the user info, without the email information (the birthday is also missing). I setted all permissions and tested with more than one account (which has email and birthday as a public information), and accepted all the dialog's requests.
Here is my init:
if(!facebook) {
facebook = [[Facebook alloc] initWithAppId:[self _APP_KEY] andDelegate:self];
NSArray *array = [NSArray arrayWithObjects: #"email", #"user_birthday", #"publish_stream", #"offline_access", nil];
[self setPermissions:array];
}
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if ([defaults objectForKey:#"FBAccessTokenKey"] && [defaults objectForKey:#"FBExpirationDateKey"]) {
facebook.accessToken = [defaults objectForKey:#"FBAccessTokenKey"];
facebook.expirationDate = [defaults objectForKey:#"FBExpirationDateKey"];
}
if (![facebook isSessionValid]) {
[facebook authorize:permissions];
}
else {
[self getUserInfo];
}
The login callback:
- (void)fbDidLogin {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:[facebook accessToken] forKey:#"FBAccessTokenKey"];
[defaults setObject:[facebook expirationDate] forKey:#"FBExpirationDateKey"];
[defaults synchronize];
[self getUserInfo];
}
The getUserInfo method:
- (void) getUserInfo {
[facebook requestWithGraphPath:#"me" andDelegate:self];
}
The request callback:
- (void)request:(FBRequest *)request didLoad:(id)result {
if ([result isKindOfClass:[NSDictionary class]]) {
NSDictionary* json = result;
NSLog(#"-> %#", json);
}
}
The result is the following:
-> {
"first_name" = EDITED (my name);
gender = male;
hometown = {
id = 111072692249998;
name = "Porto Alegre";
};
id = 653099452;
languages = (
{
id = 104034306299811;
name = "Brazilian Portuguese";
},
{
id = 106059522759137;
name = English;
}
);
"last_name" = EDITED (my last name);
link = EDITED (my profile);
locale = "en_US";
location = {
id = 112047398814697;
name = "S\U00e3o Paulo, Brazil";
};
name = EDITED (my name);
timezone = "-3";
"updated_time" = "2012-04-25T13:36:51+0000";
verified = 1;
}
As you can see, there is no information about the user's email. Am I missing some step? Any ideias?
Thanks in advance
Try to use this, it works in my case
facebook = [[Facebook alloc] initWithAppId:[self _APP_KEY] andDelegate:self];
[facebook authorize:[NSArray arrayWithObjects:#"email",nil]];
Try this
permissions = [[NSArray alloc] initWithObjects:#"offline_access",#"email",nil];
you can get the user email like this .. after the fbDidlogin fired call this method
- (void)fetchUserDetails {
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"SELECT uid, name, pic, email FROM user WHERE uid=me()", #"query",nil];
[fb requestWithMethodName:#"fql.query"
andParams:params
andHttpMethod:#"POST"
andDelegate:self];
}
and in the request:(FBRequest *)request didLoad you will do something like this:
- (void)request:(FBRequest *)request didLoad:(id)result
{
if([request.url rangeOfString:#"fql.query"].location !=NSNotFound)
{
if ([result isKindOfClass:[NSArray class]] && [result count]>0) {
result = [result objectAtIndex:0];
}
if ([result objectForKey:#"email"]) {
NSLog(#"%#",[result objectForKey:#"email"]);
}
}
}
Enjoy :)
1) Give the permission to get the Email and the info etc...
// You must ALWAYS ask for public_profile permissions when opening a session
[FBSession openActiveSessionWithReadPermissions:#[#"public_profile",#"user_videos",#"email"]
allowLoginUI:YES
completionHandler:
^(FBSession *session, FBSessionState state, NSError *error)
{
// Retrieve the app delegate
AppDelegate* appDelegate = [UIApplication sharedApplication].delegate;
// Call the app delegate's sessionStateChanged:state:error method to handle session state changes
[appDelegate sessionStateChanged:session state:state error:error];
}];
2) to get the Email where you want...
if (FBSession.activeSession.isOpen)
{
[[FBRequest requestForMe] startWithCompletionHandler:
^(FBRequestConnection *connection,
NSDictionary<FBGraphUser> *user,
NSError *error)
{
if (!error)
{
NSString *userEmail = [user objectForKey:#"email"];
}
[tblSettingVw reloadData];
}];
}
Note : User Dictionary will Return following
{
"first_name" =;
gender =;
id =;
"last_name" =;
link = "";
locale = "";
name = "";
timezone = "";
"updated_time" = "";
verified = ;
}
All facebook accounts which are verified through Phone Number instead of email will get NULL for [user objectForKey:#"email"]
You can only access an user's email if you get the user's authorization for it.
The public graph does not provide this information.
You should read this: https://developers.facebook.com/docs/guides/web/#login
You need to ask permission to the user for this information via:
- (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI {
NSArray *permissions = [[NSArray alloc] initWithObjects:
#"user_birthday",
nil];
return [FBSession openActiveSessionWithPermissions:permissions
allowLoginUI:allowLoginUI
completionHandler:^(FBSession *session,
FBSessionState state,
NSError *error) {
[self sessionStateChanged:session
state:state
error:error];
}];
}
Here's all the info you need, just follow this tutorials
First, this one: Facebook Login
And then, this one: Fetch user data

Get friends info from Facebook on my iPhone app

I am developing an application for iPhone that uses facebook.
I need to get my data (the data of current user).
I'm sure I made the correct login and have obtained the proper permissions.
Now,
I want a NSArray with the data and make a print with NSLog oh this data.
I have made this for the friendlist and i have no problem:
-(IBAction)friendsInfo:(id)sender{
// get the logged-in user's friends
[facebook requestWithGraphPath:#"me/friends" andDelegate:self];
}
- (void)request:(FBRequest *)request didLoad:(id)result {
//ok so it's a dictionary with one element (key="data"), which is an array of dictionaries, each with "name" and "id" keys
items = [(NSDictionary *)result objectForKey:#"data"];
for (int i=0; i<[items count]; i++) {
NSDictionary *friend = [items objectAtIndex:i];
long long fbid = [[friend objectForKey:#"id"]longLongValue];
NSString *name = [friend objectForKey:#"name"];
NSLog(#"id: %lld - Name: %#", fbid, name);
}
}
But for my info the same method not work:
-(IBAction)myInfo:(id)sender{
// get information about the currently logged in user
[facebook requestWithGraphPath:#"me" andDelegate:self];
}
Can someone help me?
use this function to get your faceBook Info (logged in user info)
- (void)fetchUserDetails {
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"SELECT uid, name, pic FROM user WHERE uid=me()", #"query",nil];
[fb requestWithMethodName:#"fql.query"

sessionView = session;
[[FBRequest requestWithDelegate:self] call:#"facebook.friends.get" params:params];
}
- (void)request:(FBRequest*)request didLoad:(id)result {
