Write an iPhone application

Hi, I'm looking for an iOS developer to fine tune some issues with an iOS game that I have in the Appstore. Basically there are 3 x buttons that are not working/responding when tapped. These issues became apparent after I submitted a new build which was rejected (as the IAP button was not working) - I cross checked the IAP Identifiers and these are entered correctly in the code. The other 2 x buttons should open to Game centre Achievements (ID's set up correctly and live - accessible via a GC Leaderboard button so again not the problem) I would also appreciate checking the Facebook share message. It should automatically have text and image from game over screen. (This seems to work on simulator however not so on actual device - a simple download and check may show this) If not working maybe Facebook SDK is outdated? The game can be downloaded/checked here: [login to view URL] I have also attached a .jpeg file to show which buttons are not working. Build is required (only successful) with Xcode 6 & Yosemite OS. **For some reason the game will not build correctly in the latest version of Xcode (I had to revert back to Xcode 6 to get a successful build) I have also reverted back to Yosemite OS on my Mac as there seems to be some issue/correlation with El Capitan OS?** I will provide a link via Dropbox or OneDrive for the code and provide iTunes connect details for the successful applicant. (I'm assuming a simple solution that i have overlooked) Thank you for viewing my post. Kind regards, Andrew
