I need to implement a custom image crop on iOS and I can't seem to be able to find a technology that will allow me to do that easily. The goal is to have an interface as follows:
The idea is to have some sort of path or something around the face that the user can "nudge" around with their finger. Is there a library for this?
I have played a bit with UIBezierPaths, but I don't see how they can be edited after being stroked.
The best that I can come up with is having the user manually draw a line around the face, but then the line wouldn't be editable.
Please help! Does anyone know of a solution for this? I am in a bind and need to provide my client with a solution.
