QSKit is a collection of categories and utilities that we use in our software. The project includes unit tests so we can build on a solid foundation.
None of it is high-tech. It’s just some basics, our standard kit.
Any given app may not need everything, and so we don’t build it as a framework. Instead, an app uses exactly what’s needed. (But note that some things may depend on other things.)
Category methods are prefixed with qs_. This isn’t beautiful, but it does mean our methods won’t collide with Apple’s methods, and it makes it easier to spot category methods.
Many of the categories for collections are for adding or getting objects safely — that is, they won’t throw an exception if a key is nil (for instance).
But there are a bunch of other categories too — -[NSData qs_hexadecimalString] and -[NSNotificationCenter qs_postNotificationNameOnMainThread:object:userInfo:] are examples.
Often you don’t care about the difference between nil and just not containing anything — an empty NSString, an NSArray with zero elements, and so on.
QSIsEmpty works with strings, collections, and NSData. It’s convenient, and it makes it clear when you don’t care about that difference.
QSSAXParser wraps libxml’s SAX parser. (There’s a QSOPMLParser to help you figure out how to use it.)
QSBlocks contains some commonly-used block definitions.
QSPlatform includes #defines to make writing cross-platform (iOS and Mac) easier.
QSMath has functions that work with 32-bit and 64-bit CGFloats.
QSNode is a tree representation.
QSDateParser is a fast parser for internet dates.
QSImageRenderer is a block-based system for rendering images in the background.
QSScaling does the math for scaling images (aspect-fit or aspect-fill).
QSDatabaseQueue works with FMDB. (FMDB is available separately from Flying Meat.)
QSHTTPConstants and friends in the Web group are some of the building blocks for building web services clients.
Xcode’s test system wants an app, so there’s a Mac app included. It doesn’t do anything.
Open the project and choose Product > Test (or hit cmd-U) to run the tests.
We’ll keep adding to QSKit. The kit is forever a work in progress.
Q Branch Standard Kit is available under the MIT license. See the LICENSE file for details.
