Is there any way to blur AVCaptureSession's videoPreviewLayer ?

Question

I have a custom camera created AVCaptureSession and i want to "blur" the AVCaptureVideoPreviewLayer(a layer with blur effect would be nice). I know about UIVisualEffectView,as i know, there is not any way to modify it's layer,so i could animate it's path. Any suggestions ?

Answer 1

为了实现这一点，我创建了一个遮罩并将其应用于UIVisualEffectView。

Heres是完整指南

使用模糊效果创建UIVisualEffectView。将其作为子视图添加到您的视图中，因此它将覆盖videoPreviewLayer。创建一个带孔的面具。将该掩码应用于visualEffectView。
