I'm seeking a library, or bit of code I can incorporate into a Cocoa project where I can turn a stream of text with ansi color control codes into an attributed string. There are many projects that do this, but having examined their code they're either messy or overly complex. Has anyone an idea of a simple piece of code, or library, or...

The corresponding C/C++ code compiles perfectly under gcc. #import <Foundation/Foundation.h> const float a = 1; const float b = a + a; // <- error here int main (int argc, const char * argv[]) { NSAutoreleasePool...
Hello I currently have an array of strings, I'm getting a NSString object from this array by calling the -componentsJoinedByString: method. Example: NSString *someString = [[NSString alloc] initWithString: [myStrings componentsJoinedByString:@","]; Since -componentsJoinedByString: returns me an NSString, I'm assuming that it is not "...

I'm having trouble creating a mouseover function with an NSTableView. The idea is that (if the feature is selected in prefs) placing the mouse pointer above a particular row in an NSTabelView will display a small popup window with additional information regarding the entry in that particular row. The effect should not be immediate (as e....
How do I create a cache for a struct pointer object in Objective-C? Is there any third party component for caching objects as Java and .NET have? I have the following struct: typedef struct _news { references char *headline; char *story_url; } news; I have a double pointer for the above struct in an interface class. I would lik...

Specifically, I seem to be able to get the "Auth" token correctly, but attempts to use it in the header when I access later pages still just return me the login page's HTML. Following links related to this post, I've determined that you need to make a subsequen...

HashTables/HashMaps are one of the most (if not the most) useful of data-structures in existence. As such, one of the first things I investigated when starting to learn programming in Cocoa was how to create, populate, and read data from a hashtable. To my surprise: all the documentation I've been reading on Cocoa/Objective-C programmi...
