Question 1

How to use BusyNavigationBar in a SwiftUI app?

Accepted Answer

Since BusyNavigationBar is built for UIKit, you need to wrap it in a UIViewControllerRepresentable to integrate it into SwiftUI views, which adds complexity compared to native SwiftUI solutions. This involves creating a bridge that manages the UINavigationBar instance.

Question 2

BusyNavigationBar vs UIActivityIndicatorView: which should I choose?

Accepted Answer

BusyNavigationBar is better for integrated, stylish loading animations within the navigation bar with custom visuals, while UIActivityIndicatorView is a standard, accessible component suitable for general loading indicators across the UI with better out-of-the-box iOS consistency.

Question 3

How to create a custom animation layer for BusyNavigationBar?

Accepted Answer

Set the animationType to .CustomLayer and provide a closure that returns a CALayer with your custom animation, as shown in the README code snippet. You'll need to design the layer's properties and animations using Core Animation frameworks.

Question 4

Does BusyNavigationBar support iOS dark mode?

Accepted Answer

Yes, but not automatically; you can configure the color property using dynamic UIColor (e.g., UIColor.systemGray) to adapt to dark mode. However, you must handle trait collection changes manually since the library doesn't provide built-in dark mode adjustments.

Question 5

How to stop the animation after a network request finishes?

Accepted Answer

Call the stop() method on the navigation bar instance in the completion handler of your network request. For example, use URLSession or Alamofire completion blocks to ensure the animation stops when data is fetched or an error occurs.

Question 6

Can I use BusyNavigationBar with multiple navigation controllers in an app?

Accepted Answer

Yes, you can apply it to any UINavigationBar instance by calling start() and stop() on each navigation controller's navigation bar. However, you need to manage the animation state separately to avoid conflicts or unintended overlaps across different screens.
