Answer 1

You should use "picture" instead of "photo" to get user profile photo.
And you can get userID form the accessToken like:
FBSDKAccessToken* token = [FBSDKAccessToken currentAccessToken];
NSString *ID = token.userID
When log in:
To get birthday, you need permission "user_birthday"
To get location, you need permission "user_location"
You can test everything in Facebook Graph API Explorer before implementing in your app.
To request for permission when logging in, sample code:
FBSDKLoginManager* login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions:#[#"public_profile",#"email",#"user_birthday"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
//your code to handle login result
}];
