This method gets called three times when the UITableView is loaded - once with the actual region and then two more times with a region that is way off. In the simulator...

What I am looking for is a way to get this information at a lower level, in C code (no Objective-C involved), and in particular I'm thinking of Core Foundation data structures, similarl...
I have 2 or 3 views in my iPhone application where I have various pieces of functionality that use delegates. In all cases the delegates are assigned to "self", responding specifically to that view's actions and interacting with instance variables. However, if I do something that takes a bit of time with a delegate, and leave the view, ...

We're using UIGetScreenImage to capture 3-6 images per second and saves them to disk. However, we are looking for a way to capture images at a faster rate. We've noticed some implementations that appear not to use UIGetScreenImage (we know this because they're overlaying controls in the preview that isn't captured on the image) and they'...

I inherited an OpenGL iPhone app code which has some large PNG files (say, sunshine.png, 10,000 px by 80 px) and a corresponding PLIST file for each png (say, ImageData/sunshine.plist). The trouble is, when I replace the PNG files, the app doesn't pick them up, apparently because it doesn't really read the PNG, just the corresponding ...

It then works with teh string. The problem is, I'm not sure how to pull the string out. Here is the relative code: NSUserDefaults *prefs = [NSUserDefau...
