Associative arrays in Objective-C

[bauhsoj]

Does objective-c offer the ability to natively create associative arrays such as those in PHP, Perl, or JavaScript?

Associative arrays are more commonly known as hash maps or hash tables. Here's the documentation for hash tables in Objective-C. http://developer.apple.com/document...ns.html#//apple_ref/doc/uid/20000055/BCIBDCCF

You also might want to look at NSDictionary which is a bit closer to what you want in practice.

That's cool. Didn't know about NSDictionary .

So which do you think would be best to start with for someone who programs primarily in PHP? NSDictionary or hash tables?

I am pretty new to objective-c and Cocoa, but I use associative arrays in almost every aspect of my code so I need to understand an equivalent structure in objective-c.

Look at NSDictionary. The following page should get you started. http://developer.apple.com/document...ions/index.html#//apple_ref/doc/uid/10000034i

Thanks!

Can Dictionaries be looped through using foreach to access both keys and values similar to the way it is done in PHP? I haven't found an example of that yet in the manual at the ADC.
