FXBlurView

FXBlurView is an iOS view component that renders a live, dynamically blurred version of the content behind it, giving developers a lightweight way to create frosted-glass and translucency effects. It was designed before Apple’s system blur views became widely available, so it focuses on portability and control rather than tying you to a specific iOS version. The view captures the underlying layer hierarchy and applies a configurable blur, optionally with tinting and saturation adjustments, to match many design styles. Because it updates on the fly, it can respond to animations and scrolling, keeping the blur visually coherent as content moves. The implementation emphasizes performance, using caching and adjustable update intervals so you can trade accuracy for speed on older devices. It’s useful anywhere you want depth and hierarchy cues—overlays, modals, toolbars—without manually pre-blurring assets in a graphics editor.
