Question 1

How do I handle layout changes with PinLayout in iOS?

Accepted Answer

You must update layouts manually in `UIView.layoutSubviews()` or `UIViewController.viewDidLayoutSubviews()` to respond to device rotation or size changes, as PinLayout doesn't use auto layout constraints. This ensures views are repositioned correctly based on the new bounds.

Question 2

PinLayout vs Auto Layout: which should I use for my app?

Accepted Answer

Use PinLayout for performance-critical UIs like scrollable lists or animations where auto layout is too slow, and you need full control. Choose auto layout for projects relying on Interface Builder, adaptive layouts with minimal code, or when automatic constraint updates are preferred.

Question 3

Can I use PinLayout with Interface Builder?

Accepted Answer

No, PinLayout is purely code-based and doesn't integrate with Interface Builder's visual constraints. You define all layouts programmatically using its chainable API, which may require extra effort for visual design workflows.

Question 4

How to support safe area insets in PinLayout?

Accepted Answer

Use `UIView.pin.safeArea` property, which provides backward-compatible safe area insets for iOS 7–10 and aligns with iOS 11+ `safeAreaInsets`. Methods like `all(pin.safeArea)` or `top(pin.safeArea)` easily incorporate safe areas into layouts.

Question 5

What are best practices for complex UIs with PinLayout?

Accepted Answer

Break down layouts into smaller views, use relative positioning methods like `below(of:)` and `after(of:)`, and leverage `sizeToFit()` for content-based sizing. Regularly test on different device sizes and orientations since layouts are manual.

Question 6

How does PinLayout handle animations?

Accepted Answer

PinLayout supports animations by updating layout properties within animation blocks, such as changing `width()` or `top()` values, but you must manually trigger layout updates in `layoutSubviews()` to reflect animated changes smoothly.
