ios - GPUImageview disappear after capture it -

i seek capture gpuimageview using link

but after capture gpuimageview disappear, if uiimageview working fine.

i answered in your cross-posted question on github, reason line in above-linked documentation states:

note that, calayer/-renderincontext: captures uikit , quartz drawing. not capture opengl es or video content.

gpuimageview presents content using opengl es, can't capture using -renderincontext:. you'll either need extract filter's image , manually composite underlying view, or perform compositing within gpuimage using blend filter.

ios objective-c gpuimage
