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.
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.
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_SECRET @"1234567890"
#define VIMEO_CONSUMER_KEY @"1234567890"
#define VIMEO_BASE_URL @"http://vimeo.com/services/auth/"
#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"
