I ran into an issue where ASIFormDataRequest does not actually make a request, or call failed block.
This all worked fine under debug builds. Only when I deployed ad hoc builds I realized that something was failing. After some experimentation, I discovered that changing the compiler optimization -Os to O0 made the issue go away.
I am posting it here so that others may find this issue without spending hours trying to debug.
I love this solution, I have been banging my head on the wall for one day!
I ran into the same issue. I really wish someone would update this library so I can turn optimizations back on. It would be nice if someone made it ARC friendly as well.
