Objective c FBConnect iOS SDK发布\操作问题
我必须说我现在觉得自己像个白痴我在Facebook、Google和StackOverflow上下翻来覆去，仍然无法找到我做错了什么的答案！：）我看过两个Facebook的例子：Objective c FBConnect iOS SDK发布\操作问题,objective-c,ios,facebook-graph-api,facebook-opengraph,fbconnect,Objective C,Ios,Facebook Graph Api,Facebook Opengraph,Fbconnect,我必须说我现在觉得自己像个白痴我在Facebook、Google和StackOverflow上下翻来覆去，仍然无法找到我做错了什么的答案！：）我看过两个Facebook的例子：Hackbook和WishListWishlist显然应该告诉我该做什么，但是我看到的所有示例都将对象作为URL。我不一定希望这样，因为我只想让帖子说（这个用户）正在玩[MyGame] 好的，这是我的目标。我有一个iPhone游戏。我想做的是Spotify在听一首歌时所做的事情，这首歌会发布到timeline和ticker

@end如果我们可以在应用程序本身中将这些东西定义为我不需要网站的情况下的参数，那就太酷了。从2012年4月21日起，Facebook要求你创建一个页面来获取所需的数据。我想做同样的事情，比如，在不创建带有元标记的关联网页的情况下发布操作。因此，本质上，它只在创建页面之后才起作用。对吗？对。截至2012年3月9日，我只能通过创建一个页面来实现这一点。
