JKCategories is a collection of useful Objective-C categories that extend iOS frameworks such as Foundation, UIKit, CoreData, QuartzCore, CoreLocation, and MapKit. It is distributed via CocoaPods with granular sub-specs so developers can import categories per framework or per class.

Use cases

• add safe-access methods to NSArray and NSDictionary in iOS apps
• extend UIKit classes like UIImage, UIButton, and UIColor with helper methods
• simplify NSDate formatting and manipulation in Objective-C
• get a curated set of iOS category extensions via CocoaPods
• avoid crashes from out-of-bounds or nil access in Foundation collections
• import one header to get all categories for a framework like UIKit or Foundation

When to choose

• you are building an iOS app in Objective-C and want battle-tested category extensions
• you want fine-grained CocoaPods subspecs to include only the categories you need
• you need safe-access helpers for Foundation collection classes

When to avoid

• you are developing in Swift with a Swift-first codebase
• you target only modern SwiftUI projects with little UIKit/Foundation usage
• you prefer minimal dependencies and want to write only the few helpers you need
