Now, of course I am not just doing a simple addition in the loop, I create objects, set some of their properties, do some calculations with them, and add them to an array. Some of the objects are from my own project, but some of them are from a 3rd party framework. Should I add the __block to all the properties of these objects as well? I can do that for the objects from my own project, but the objects from the other framework are not ARC (my project is), and I get a crash at the dealloc method for these. Is there a way to solve this?
