How to get user name and email id for Facebook SDK?
facebook, ios, iphone, objective-c
Solution
Use the Following Code
FBSession *session = [[FBSession alloc] initWithPermissions:@[@"basic_info", @"email"]];
[FBSession setActiveSession:session];
[session openWithBehavior:FBSessionLoginBehaviorForcingWebView
completionHandler:^(FBSession *session,
FBSessionState status,
NSError *error) {
if (FBSession.activeSession.isOpen) {
[[FBRequest requestForMe] startWithCompletionHandler:
^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
if (!error) {
NSLog(@"accesstoken %@",[NSString stringWithFormat:@"%@",session.accessTokenData]);
NSLog(@"user id %@",user.id);
NSLog(@"Email %@",[user objectForKey:@"email"]);
NSLog(@"User Name %@",user.username);
}
}];
}
}];
Problem
The code I have used ``` if (FBSession.activeSession.state == FBSessionStateOpen || FBSession.activeSession.state == FBSessionStateOpenTokenExtended) { // Close the session and remove the access token from the cache // The session state handler (in the app delegate) will be called automatically [FBSession.activeSession closeAndClearTokenInformation]; // If the session state is not any of the two "open" states when the button is clicked } else { // Open a session showing the user the login UI // You must ALWAYS ask for basic_info permissions when opening a session [FBSession openActiveSessionWithReadPermissions:@[@"basic_info,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]; }]; } ``` from this code i need to get user name and mail id. if any one know the solution please help me thanks in advance.
