Can anyone tell me if the following is implementable and if yes point me in right direction. Let's say we have a picture on the screen in our iOS app. Then i select an area on this picture drawing a shape with my finger and then the selected area gets cut off and becomes a separate image i can work with. Is that possible?

fast answer: yes it is possible
look at https://github.com/iridia/UIImage-Additions
- (UIImage *)croppedImage:(CGRect)bounds; in UIImage+Resize.h
this method is what you are looking for to cut your image
your job is to calculate the bounds from your screen selection
