Question

我正在使用以下Graph API请求来吸引所有喜欢特定对象的朋友：

me/?fields=friends.fields(likes.target_id(searched_object_id))

iOS代码如下：

[ FBRequestConnection startWithGraphPath: [ NSString stringWithFormat: @"me/?fields=friends.fields(name,likes.target_id(%lld))", 7919071058 ]
                 completionHandler: ^(FBRequestConnection *connection, id result, NSError *error) {
                     [ [ [ result objectForKey: @"friends" ] objectForKey: @"data" ] enumerateObjectsUsingBlock:^(id friend, NSUInteger idx, BOOL *stop) {
                         if ( [ friend objectForKey: @"likes" ] )
                             NSLog( @"%@ also likes that", [ friend objectForKey: @"name" ] );
                     } ];
                 }
 ];

不幸的是，我想对og.likes做同样的事情.target_id不可用

有关信息，og.likes是打开的图形对象，您可以在应用中声明。（https://developers.facebook.com/docs/opengraph/tutorial/）

先谢谢你的帮助

此处遵循修改后的代码以使用og.likes

[ FBRequestConnection startWithGraphPath: @"me/?fields=friends.fields(name,og.likes)"
                     completionHandler: ^(FBRequestConnection *connection, id result, NSError *error) {
                         [ [ [ result objectForKey: @"friends" ] objectForKey: @"data" ] enumerateObjectsUsingBlock:^(id friend, NSUInteger idx, BOOL *stop) {
                             [ [ [ friend objectForKey: @"og.likes" ] objectForKey: @"data" ] enumerateObjectsUsingBlock:^(id ogLike, NSUInteger idx, BOOL *stop) {
                                 if ( [ [ [ [ ogLike objectForKey: @"data" ] objectForKey: @"object" ] objectForKey: @"id" ] isEqualToString: [ NSString stringWithFormat: @"%lld", idObject ] ] )
                                     NSLog( @"%@ also og.likes that", [ friend objectForKey: @"name" ] );
                             } ];
                         } ];
                     }
 ];

正如你所看到的，我必须抓住我朋友的每一个og.likes，然后遍历它们以找到匹配的那个。这是更多的带宽，但它的工作原理。如果有人找到更优雅的方式，我仍然很好奇。

此致
