Getting user data from facebook login in xcode? - iphone

Question

I have integrated facebook login in my app.But Im unable to get user data ie it is not entering the user details loop
In Appdelegate.m
- (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI {
NSArray *permissions = [[NSArray alloc] initWithObjects:
#"email",
#"user_likes",
nil];
return [FBSession openActiveSessionWithReadPermissions:permissions
allowLoginUI:allowLoginUI
completionHandler:^(FBSession *session,
FBSessionState state,
NSError *error) {
[self sessionStateChanged:session
state:state
error:error];
}];
}
- (void)sessionStateChanged:(FBSession *)session
state:(FBSessionState) state
error:(NSError *)error
{
switch (state) {
case FBSessionStateOpen:
if (!error) {
// We have a valid session
NSLog(#"User session found");
[[FBRequest requestForMe] startWithCompletionHandler:
^(FBRequestConnection *connection,
NSDictionary<FBGraphUser> *user,
NSError *error) {
if (!error) {
NSLog(#"%#",user);
}}];
break;
case FBSessionStateClosed:
case FBSessionStateClosedLoginFailed:
[[FBSession activeSession] closeAndClearTokenInformation];
break;
default:
break;
}
if (error) {
UIAlertView *alertView = [[UIAlertView alloc]
initWithTitle:#"Error"
message:error.localizedDescription
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
}
}
}
But I dont find NSLog of user NSLog(#"%#",user) to be printed eventhough the session is opened bcoz NSLog(#"User session found") is printed
Y is it so ?

I had same issue where I was not able to enter in the block once came back after log in after an hour I figured out that I was returning mysession class instead of instance of mysession. This might fix your issue:
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
return [mysession handleOpenURL:url];
}
