[Facebook-iOS-SDK 4.0]How to get user email address from FBSDKProfile

Question

I'm upgrading my app to Facebook-iOS-SDK-4.0, but seems like I can't get user email from FBSDKProfile, since it only provide, username, userid, etc.

To fetch email you need to utilize the graph API, specifically providing the parameters field populated with the fields you want. Take a look at Facebook's Graph API explore tool, which can help to figure out the queries. https://developers.facebook.com/tools/explorer

The code that worked for me to fetch email is the following, which assumes you are already logged in:

    NSMutableDictionary* parameters = [NSMutableDictionary dictionary];     [parameters setValue:@"id,name,email" forKey:@"fields"];      [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:parameters]      startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,                                   id result, NSError *error) {          aHandler(result, error);      }];
