使用FBSDKGraphRequest类似下面的代码来获得Facebook用户的用户名和个人资料照片。

一旦你登录，添加以下代码：

NSLog(@"Logged in"); 
      if ([result.grantedPermissions containsObject:@"public_profile"]) { 
       if ([FBSDKAccessToken currentAccessToken]) { 
        NSMutableDictionary* parameters = [NSMutableDictionary dictionary]; 
        [parameters setValue:@"name,picture.type(large)" forKey:@"fields"]; 

        [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:parameters] 
         startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) { 
          if (!error) 
          { 
           NSLog(@"fetched user:%@", result); 


           NSString *name = [[result valueForKey:@"name"] lowercaseString]; 
           NSString *username = [name stringByReplacingOccurrencesOfString:@" " withString:@""]; 
           NSArray *picture_arr = [result objectForKey:@"picture"]; 
           NSArray *data_arr = [picture_arr valueForKey:@"data"]; 
           NSString *profile_pic = [data_arr valueForKey:@"url"]; 

} 

}];

      NSLog(@"Logged in %@ %@", result.token.userID, result.token.tokenString); 
      [self fetchUserInfo];

-(void)fetchUserInfo 
{ 
    if ([FBSDKAccessToken currentAccessToken]) 
    { 
     NSLog(@"Token is available : %@",[[FBSDKAccessToken currentAccessToken]tokenString]); 

     [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, link, first_name, last_name, picture.type(large), email, birthday, bio ,location ,friends ,hometown , friendlists"}]
