I am using ShareKit to allow the user of an iPad application to Tweet a URL from within the application through their Twitter account. The following OAuth steps work fine:
At this stage in the OAuth flow things go wrong.
After the WebView displays a Twitter 'redirecting' message very briefly, a page saying 'Your session has timed out' is displayed.
I decided to create a Twitter application in my own personal Twitter account. When I change the app to use my own Consumer Key and Consumer Secret (but keeping the callback URL and permissions the same), everything works fine.
I have cross checked the Consumer Key and Secret with the values in the app and they match (for the Twitter account that failed).
I used Twurl and everything worked fine with both Twitter accounts. So I don't understand what could be wrong with only one of the Twitter accounts and only when using ShareKit.
I could do with some direction on how to track down the problem?
I can not help you directly but original share kit is obsolete in many ways. You might want to try ShareKit 2.0. At least, on ios5+ it uses Twitter.framework, so your problems might be gone.
