Question 1

How do I create a custom animator in RHPlaceholder?

Accepted Answer

Conform to the LayerAnimating protocol as mentioned in the README, then pass your custom Animator class as a parameter to the Placeholder initializer. This allows you to define unique animation behaviors beyond the predefined gradient or blink effects.

Question 2

RHPlaceholder vs SkeletonView: which is better for iOS loading?

Accepted Answer

RHPlaceholder is focused on gradient-based animations similar to Instagram, while SkeletonView offers skeleton screen effects for content blocking. Choose RHPlaceholder for trendy, visual placeholders; SkeletonView for more subtle, content-aware loading states. RHPlaceholder is simpler for basic animations but has fewer community resources.

Question 3

Can I use RHPlaceholder with SwiftUI?

Accepted Answer

The README doesn't mention SwiftUI compatibility, and since it's designed for UIKit and storyboards, direct integration with SwiftUI may require additional bridging or wrappers. Check the demo project for UIKit-based examples only.

Question 4

How to handle errors or retries with RHPlaceholder animations?

Accepted Answer

The library provides basic control with `startAnimation()` and `remove()` methods, but error handling or retry logic must be implemented manually in your data fetching code, as it's not built into the placeholder animations.

Question 5

Does RHPlaceholder work with CocoaPods and Carthage?

Accepted Answer

Yes, the README includes installation instructions for both CocoaPods (pod 'RHPlaceholder') and Carthage (adding the GitHub repo to Cartfile), making it flexible for different dependency management setups in iOS projects.

Question 6

What are the performance costs of using RHPlaceholder?

Accepted Answer

While not detailed in the README, gradient animations can be more resource-intensive than native UIActivityIndicatorView. For performance-sensitive apps, test on target devices to ensure smooth frame rates, especially with multiple animated views.
