有人知道如何手动清除内存中的 CG raster data吗？

Answer 1

There seems to be no solution. This is the memory area managed by the system.
You should have encountered the problem that the system memory is getting larger and larger after loading a large number of pictures

Answer 2

Not only that, when drawing the view.layer, when this page is pushed out, it will not be realised, but will always exist, causing the memory to become larger and larger. What should I do about this?
