Answer 1

As per your second method, try like this,

-(void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id<FBGraphUser>)user
{
  NSString *userDetails = [NSString stringWithFormat:@"%@",user];
  NSString *fb_userEmail = [user objectForKey:@"email"];
}

userDetails will return you all the user details in a single string object. fb_userEmail will return users email id.
