Hi everyone. I have two UIActionSheets and I am thinking that I will control them with one delegate (the UIViewController that instantiates them). The delegate will capture an actionSheet call and try to figure out which of the two threw the event. I tried to get the modalView's title to differentiate, but it seems to be invalid... S...
I'm looking for way to grab the content of my opengl (as UIImage) and then save it into a file. I'm now giving glReadPixels a try though I'm ont sure I'm doing the right thing as of what kind of malloc I should be doing. I gather that on OSX it's GL_BGRA but on the iPhone that doesn't work... ...
My application is pretty simple: it starts up with a view controller that holds a table view (in grouped view layout) with a few options. When the user taps on one of the options, I push another view controller onto my navigation controller. This second view controller simply displays a UIImageView, and the user can change the screen or...
Given the iPhone's 25k limit for caching of files, I'm wondering if there's interest in an iPhone optimized javascript library that makes caching a top level goal.

From the examples I've seen thus far on the interwebs, this is accomplished by using an NSNumberFormatter a la: NSString *s = @"0.07"; NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init]; [formatter setForm...
What is the best way to load static data files containing game level maps on the iPhone? I have seen some use XML files, but that seems like overkill in my situation as the data files merely determine the layout of the game's level, ie where obstructions will go. Also, what project directory should they be stored in? Thanks in advance...
