Question 1

How to install BlocksKit without using CocoaPods?

Accepted Answer

You can manually download a release and add BlocksKit.xcodeproj to your Xcode project, then embed the framework or link the static library by following the steps in the README, such as setting header search paths and linker flags.

Question 2

BlocksKit vs ReactiveCocoa for Objective-C block programming?

Accepted Answer

BlocksKit focuses on simplifying Cocoa APIs with blocks for KVO, delegation, and collections, while ReactiveCocoa introduces reactive programming with signals and streams. BlocksKit is lighter and more direct for block-based utilities, whereas ReactiveCocoa offers a broader paradigm shift.

Question 3

How to use BlocksKit for Key-Value Observing with blocks?

Accepted Answer

Use methods like `bk_addObserverForKeyPath:options:block:` to set up observations with block callbacks, replacing the traditional observer methods. This reduces verbosity and makes the code more declarative, as explained in the block-based KVO feature.

Question 4

Does BlocksKit work with Swift code in an iOS project?

Accepted Answer

Yes, but since BlocksKit is written in Objective-C, you need to use bridging headers or import it in a mixed project. It's not natively Swift, so integration might require additional setup and careful memory management.

Question 5

Are there any performance issues with BlocksKit's block abstractions?

Accepted Answer

BlocksKit introduces block overhead that might be slightly higher than raw C function pointers, but for most applications, the impact is minimal. The readability and maintainability gains often outweigh any minor performance trade-offs.

Question 6

How to handle memory management with BlocksKit blocks to avoid retain cycles?

Accepted Answer

You must manually manage references by using weak or unowned references when capturing self or other objects in blocks, as BlocksKit doesn't provide automatic cycle breaking. Standard Objective-C memory rules apply to prevent leaks.
