I try to get the hang of it, but for now both seem the same thing to me. However, Xcode allows to create an Console App with choice of using "Core Foundation" or just "Foundation". Maybe someone can point out the differences. ...
NSMutableArray *arr = [NSMutableArray arrayWithCapacity:3]; if ([arr isMemberOfClass:[NSMutableArray class]]) { NSLog(@"YEP!!"); } else { NSLog(@"NO!!"); } I get always "NO!!" in console. I tried with Array, NSNumber, NSString. All of them don't seem to work. That's strange. As I get it from the docs, this method should return...
I'm trying to come up with some programming puzzles focused on multi-threading. Most of the problems I've been able to come up with, so far, have been pretty domain specific. Does anybody have any decent programming puzzles for developers attempting to learn the core concepts of multi-threading applications? ...
While memory management for the foundation classes are consistent and documented, i was surprised to find (via the friendly EXC_BAD_ACCESS) that Foundation functions like e.g NSStringFromSelector() seem to return pointers to constant storage - which is at least not mentioned in the documentation for the function.

When the post comment button is clicked the user is redirected to a pr...

I understand that constant CStrings are allocated statically, rather than on the heap. I also noticed that constant NSStrings have an infinite retain count. Does it hold true that constant NSStrings are also allocated statically, rather than on the heap? ...
