Facebook在iPhone应用程序 [英] Facebook in iPhone app
本文介绍了Facebook在iPhone应用程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我可以使用用户ID登录面书
但是问题是，用户从脸书进行身份验证后，贴上你的帖子不会出现在应用程序
（我正在使用ios6 SDK ）
（我已经在Facebook中创建了我的应用程序，检查了图表中的public_action）
我已经浏览了Facebook开发者页面中提供的教程（美味），但无法使它
这是我的代码 - 如果有人发现错误或缺失的部分，请帮我清除

解决方案
由于您使用3.1版本的SDK SDK， openActiveSessionWithPermissions： allowLoginUI：completionHandler：不应该被使用，旧的方式似乎不再起作用了;从 3.1迁移文档; p>
...您将需要删除openActiveSessionWithPermissions的用法：allowLoginUI：completionHandler：并将其替换为openActiveSessionWithReadPermissions：allowLoginUI：completionHandler :(甚至更多稍后，当您的应用需要发布回Facebook时，您应该使用reauthorizeWithPublishPermissions：defaultAudience：completionHandler：寻求附加权限。

I am working on an iPhone app,in this i have an option for sharing my posts with face book(i am just passing the user id of facebook user and my server side developer do the posting part) I am able to take the user id while log in in face book But problem is-after the user authenticate from facebook,"post on your behalf" is not coming in the app (i am using ios6 SDK) (i have created my app in facebook with checked that public_action from graph) I have gone through the tutorials(scrumptious) given in facebook developer page,but could not make it
Here are my code-If any one find the error or missing part,please help me to clear that

解决方案
Since you're using the 3.1 version of Facebook SDK, openActiveSessionWithPermissions:allowLoginUI:completionHandler: is not supposed to be used and the old way of doing it does not seem to be functional anymore; from the 3.1 migration documentation;
...you will need to remove usage of openActiveSessionWithPermissions:allowLoginUI:completionHandler: and replace it with openActiveSessionWithReadPermissions:allowLoginUI:completionHandler: (or even more simply, openActiveSessionWithAllowLoginUI).
Later, when your app needs to publish back to Facebook, you should use reauthorizeWithPublishPermissions:defaultAudience:completionHandler: to seek the additional permissions.
Even more details available at the migration docs.
