Some time ago I read an interesting post dedicated to useful frameworks and libraries for iOS development. With your permission and consent, Coder89 presenting “Useful things for iOS developers, part two”. "Helpers":
"NSXtensions" is a collection of Cocoa helpers (categories) for standard Apple Cocoa / UIKit classes, making them more convenient to use.
“RNBoilerplate” - creating templates with specified settings, frameworks, libraries and much more.
Appirater is a very useful library that reminds the user of the application that it would be nice to evaluate it in the AppStore.
“IVersion” is a set of classes that reminds the user that a new version of the program has been released and shows what changes have occurred in it.
“IHasApp” is a framework that allows you to get a list of applications installed on the user's phone.
UI components and frameworks:
"ODRefreshControl" - a new visual method "Pull Down To Refresh", which appeared in iOS6. This library works with earlier versions of iOS.
“GHSidebarNav” is a clone of the controller entered by facebook for side out navigation.
“CHDigitInput” is a replacement for the standard UiPickerView, but intended for the selection of numbers, provides an accelerated selection especially in the case of large numbers (999999).
“REComposeViewController” - repeats the functions of SLComposeViewController, which appeared in iOS6. Helps create a visually similar controller to support social networks.
ClassicMap is an application that demonstrates how to overlay standard maps with maps from other sources.
“SDWellSegmentedControl” is a replacement for the standard UISegmentedControl repeating control from the AppStore of the application in iOS6.
"MGBox2" - the creation of stylish tables, grids with a minimum amount of code.
“DEFacebookComposeViewController” - a controller for sending photos and messages on facebook that resembles that of ios6, only supporting c work with ios4 and 5.
"KOFiles" is a powerful file explorer built on the basis of UITableView.
"PTShowcaseViewController" - also allows you to view directories and files, but is made in the style of Springboard. When you release an application with this library - remove the rounding of icons (otherwise apple will not miss).
Accordion is a file navigation assistant that replaces UINavigationController.
