Question 1

How do I add a parallax header to a UITableView in Swift?

Accepted Answer

Simply create a UIView (like a UIImageView), set it to tableView.parallaxHeader.view, and configure height and mode properties as shown in the README examples. It typically takes just 3-4 lines of code.

Question 2

ParallaxHeader vs manual implementation: which is better?

Accepted Answer

ParallaxHeader saves significant development time with its simple API, but for highly customized or performance-critical effects, a manual implementation might offer more control. This library is best for standard parallax needs.

Question 3

Can I use ParallaxHeader with UICollectionView?

Accepted Answer

Yes, but indirectly: since UICollectionView is a subclass of UIScrollView, it should work, though the README examples focus on UITableView and require careful setup for collection view layouts.

Question 4

How to change the parallax speed in ParallaxHeader?

Accepted Answer

The library doesn't expose direct speed control; effects are based on scroll progress and mode settings. You can tweak behavior via minimumHeight and maximumHeight, but for fine-grained speed adjustments, you might need to extend the code.

Question 5

Does ParallaxHeader work with iOS 15 or later?

Accepted Answer

Yes, it supports iOS 8.0+ as per the README, so it's compatible with newer versions, but testing is advised for any UIKit changes in recent iOS releases.

Question 6

How to handle blur effects with ParallaxHeader?

Accepted Answer

Use the progress handler to adjust alpha, as shown in the blur examples, but note that this requires the separate Blur library for implementation, adding an extra dependency.
