DejalFoundationCategories is a collection of Foundation-level categories, to add useful methods to classes like
NSString, and others.
They work on both OS X and iOS.
I wrote DejalFoundationCategories for my own use, but I'm making it available for the benefit of the Mac and iOS developer community.
If you find it useful, a donation via PayPal (or something from my Amazon.com Wish List) would be very much appreciated. Appropriate links can be found on the Dejal Developer page:
You can find the latest version of this code via the GitHub repository:

The methods use a

Some of the methods date back over 10 years, so may be less useful nowadays, or have outdated code style. But there are still lots of gems that are used in all Dejal apps.
