ShareKit for iPhone randomly crashing

Question

I am having some issues with ShareKit for the iPhone. I have everything I need(Twitter, Facebook, and Email mainly) working great for sending a URL. In another portion of my app however, I am trying to implement the ability to share a small bit of text. When I try to open Facebook when sharing this text, it opens the Facebook screen quickly and then it disappears. Also, the app periodically crashes when I try to share the text, but never for the URL. It seem strange for me.

I am not very experienced with things like crash logs and debugging but if anyone can direct me to the information provided by xcode when the app crashes that could potentially provide help to those expert programmers out there, I will definitely provide it.

EDIT: I just wanted to say that I copied the SHConfig file into the sample project and everything seems to work fine from there so it must be a problem with my code. This is what it is showing after the crash:

Answer 1

Hey Rob, try finding where the crash is occurring by using this method: http://stackoverflow.com/questions/1163981/how-to-add-a-breakpoint-to-objc-exception-throw

Then post back the Object/method that is causing the crash.

You may also want to try copying your SHKConfig.h file from your project into the example project provided in ShareKit to see if the crash still occurs. If it does, then it's a problem with Sharekit, if it does not, the problem is within your own app.

Answer 2

Not a real answer to you question, but I use PinkelStar to implement native sharing. Works quite well, and provides extra stats.

Answer 3

I found the source of the problem, but have no idea how to fix it for what I was trying to do. I was trying to launch ShareKit from a button in a UIAlertView. Apparently, Sharekit needed to be launched from a simple button on the screen, or a UIActionView. I went with a UIActionView and now it works.
