Application Failure in Cydia Repo

I've recently made a repo for cydia and posted my application on it. When I download my app it installs perfectly find, but when I launch it, it will suddenly close. It works fine on the simulator, but I don't know whats going wrong. Can anyone pinpoint me to where I have a mistake. BTW I deleted all the DS_St开发者_运维问答ore stuff out of the repo folder.

Thanks

You probably either didn't sign your app's binary with ldid -S yourbinary, or didn't package the .deb file correctly. Follow this tutorial to make a repo/.deb file: http://www.saurik.com/id/7
