About a dozen useful opensource libraries for iOS developers

After the last time I wrote an article about CocoaPods basics, I got the idea that the library of pods can and should be used as an excellent source of opensource iOS projects for both beginners and experienced programmers. After installing the cocoapods ruby ​​package (all in the same article), you will be able to search useful libraries for keywords directly from the command line:

And that's what the community is using now.


Work with images:

1) SDWebImage Asynchronous loading of images, support for caching policies. There is a functionality for pre-decoding an image, it helps about scrolling.
2) GPUImage A powerful library for image processing, the ability to impose effects directly on the camera output in real time. I think at least half of the participants of the recent contest (http://vk.com/photo_contest) on VKontakte used it.
3) NYXImagesKit is a general purpose library that adds many useful methods for processing: filters, resizing, rotation, and more.
4) XBImageFilters To some extent an alternative to GPUImage.

Work data on disk:

1) NLCoreData Wrap around Core Data for simpler and more readable operations.

3) iActiveRecord This is the implementation of the ActiveRecord pattern, but without the support of Core Data.
4) FileMD5Hash Calculates MD5 file content, consumes relatively little RAM.
5) FMDB Wrap around sqlite.

Work with the network, http requests:

1) ASIHTTPRequest A convenient wrapper around the CFNetwork API for HTTP requests.
