The NSString method initWithFormat:arguments: takes a va_list as an argument. I can't figure out when it would be used (or even how to use it). Why would Apple add such a method when the regular initWithFormat: is much more user-friendly? ...

In UILabel there's functionality to truncate labels using different truncation techniques (UILineBreakMode). In NSString UIKit Additions there is a similar functionality for drawing strings.

Hi, I've seen a few posts on here about the issue of using retain or copy for strings. I still can't quite get my head around the difference or the importance. In my case at the moment I have a class with a whole load of nsstrings to hold strings. I want this class to only be instantiated once and I want its nsstring variables to chan...
Hi all, I want to check an NSString for special characters, i.e. anything expect a-z, A-Z and 0-9. I don't need to check how many special characters are present, or their positions, I just need to know whether a particular string contains any or not.

When I debug, I never get the value of an NSString inside of an array. All I see are cryptic symbols, probably memory addresses of something like 0x1dc3753. I dig into all the stuff and expand everything, but no humanly readable value at all. Not really useful at all. How do you go about this (besides NSLogging everything)? ...
