Facebook iOS SDK not returning user email - iphone

Question

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

Answer 1

Try to use this, it works in my case
facebook = [[Facebook alloc] initWithAppId:[self _APP_KEY] andDelegate:self];
[facebook authorize:[NSArray arrayWithObjects:#"email",nil]];

Answer 2

Try this
permissions = [[NSArray alloc] initWithObjects:#"offline_access",#"email",nil];

Answer 3

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 :)

Answer 4

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 = ;
}

Answer 5

All facebook accounts which are verified through Phone Number instead of email will get NULL for [user objectForKey:#"email"]

Answer 6

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

Answer 7

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
