I came across a problem that seems to be called "drowning" in autorelease pools. My code creates and destroys objects correctly. However, I use some class methods that autorelease several variables without my knowing about it. Considering they loop thousands and thousands of times every minute... I find myself drowning in thousands of u...
Hi, I hate having memory leaks and usually pride myself on, blah, blah, blah. Help! The leaks I have aren't crazy big (a few K at max), but I want to remove them for sure.

Merging those is a pain and often results in lost file references if you're not careful. Has anyone worked out a tried an...

I have an app project that I upgraded to a Universal App for the iPad. XCode created a Resources-iPad folder and duplicated my .xib file in there with the -iPad tacked onto the file name. That's all well and good. But when I edit that XIB it doesn't seem to understand this is an iPad XIB. For instance, the Window object is 320x480 an...

I'm developing an iPad application and I'm not sure what's the best way to store application data. So far I've been using a .plist that stores hundreds of strings for a puzzle game and that works great, but if my app is to be any good, it's going to have to store tens of thousands of strings (representing pre-made puzzles).
