This is a collection of useful classes and extensions for common classes in CoreFoundation and UIKit.

• Various categories to make the standard CoreFoundation and UIKit classes more useful
• A few helper classes with the same purpose

• As of version 0.2.0, all code requires an ARC (Automatic Reference Counting) capable compiler.
• Everything should be compatible with the iOS SDK 5 or above. Since version 0.5, OS X should be supported as well.

Just copy the files you need (and their dependencies) to your project.

You can also use objc-utils with CocoaPods.

Over time, some categories were removed, since their functionality is offered in separate projects:

• Use KSCrypto instead of NSString+Hash. Note, however, that the resulting hashes are different, as NSString+Hash used Base32 encoding to convert hashes to strings.
• Use the GZIP instead of NSData+CocoaDevUserAdditions. GZIP, using the default compression/decompression methods is fully compatible to NSData+CocoaDevUserAdditions.
• All UIKit-related functionality was moved to uikit-utils and ios-versioncheck.

MIT. (Before version 0.5.0, a custom permissive license was used.)
