Debugged and fixed LinkedIn crash when running on Xcode 5.1; issue was found to be in the MFLinkedInUIActivity class’s activityViewController method, I was setting a local variable to be the transition delegate of the activityViewController which was wrong since after that method execution the app didn’t have any reference to the transition delegate and the result was a bad access runtime crash. To fix the bug I added the transition delegate as a property of the MFLinkedInUIActivity class so as long as the activity is living, there’ll be a reference to the delegate. Performed tests to ensure there wasn’t similar mistakes throughout the library. Made minor refactoring, specifically where there was CGFloat and NSInteger code; to help in the 64-bit transition. Updated LinkedIn library demo app to initialize the custom UIActivity with LinkedIn API and Secret keys.
