I'm writing a sound library, for the iPhone, that uses OpenAL. The app generates a unique buffer id for each sound, during startup. The problem that I'm having is that OpenAL is unable to generate more than 1024 buffer ids.

I hadn't made any changes to my data model or the data access code for over a month, so I don't think it can be anything that I'm doing wrong as far as interacting with Core Data. (Meaning, the URLs are ok,...

Hi all, I've seen several posts with people having this issue but no solutions. Basically clicking a UITextField to show the keyboard for the first time eats up ~4mb of memory (according to the activity monitor) and I never get that memory back (and I need it back :P). I know that UIKit will often take up a large chunk of memory for t...
