问题描述
我开发从中我要上传视频到Vimeo，Facebook和YouTube的应用程序。 Facebook和YouTube的pretty简单的API，Vimeo的具有良好的开发文档，但没有目标C框架。我见过一对夫妇的应用它们使用Vimeo的，所以我想知道是否有某种框架在那里的，我不知道。
I am developing an app from which I want to upload Videos to Vimeo, Facebook and Youtube. Facebook and Youtube have pretty straightforward apis, Vimeo has a good developer documentation, but no Objective C framework. I have seen a couple of Apps which use Vimeo, so I was wondering if there is some kind of Framework out there I'm not aware of.
推荐答案
OK大家。如果你在如何将视频上传到Vimeo仍然有兴趣，这里的code。首先，你需要用VIMEO注册一个应用程序，并获得你的秘密和消费者的关键。然后，你需要得到从谷歌GTMOAuth框架和可能SBJson框架。目前，我很遗憾没有清理低于code中的时间，但我认为这可能是比什么都没有为那些，谁需要一些帮助VIMEO更好。基本上你用VIMEO认证，获得门票上传，上传视频与此票据，然后广告标题和一些文字。
OK everybody. If you're still interested in how to upload a video to vimeo, here's the code. First you need to register an App with vimeo and obtain your secret and consumer key. Then you need to get the GTMOAuth framework from Google and possibly the SBJson framework. At the moment I unfortunately don't have the time to clean up the below code, but I thought this may be better than nothing for those, who need some help with vimeo. Essentially you authenticate with vimeo, get an upload ticket, upload the video with this ticket and then ad a title and some text.
在code以下无法开箱的，因为有连接几个视图中的元素，但它应该给你发生了什么事情的理解。
The code below won't work out of the box, because there are a couple of view elements connected, but it should give you an understanding of what is happening.

#define VIMEO_CONSUMER_KEY @"1234567890"

#define VIMEO_REQUEST_TOKEN_URL @"http://vimeo.com/oauth/request_token"
#define VIMEO_AUTHORIZATION_URL @"http://vimeo.com/oauth/authorize?permission=write"
#define VIMEO_ACCESS_TOKEN_URL @"http://vimeo.com/oauth/access_token"
