Hello ,guys,

My app needs to get the camera data from Iphone. In my ImagePickerController, there is overlayView drawing realtime indications.

I use UIGetScreenImage() to get the screenshot, and I also dump overlayview to image, then I can restore the original Image based on these two images.

if the overlayView is still, it works quite well, but if the overlayView keeps changing, UIGetScreenImage() can not keep up with it.

For example,if the overlayView changes from a rectangle to a circle, then calling UIGetScreenImage() returns with a rectangle on top of it.

Is there a way to get the realtime camera data? I really appreciate if someone could help.
