Add circular crop to a controller

Hi everybody, First, please have a look at this open controller : [login to view URL] I want you to modify this controller (or if you can do something without modifying it it is better as I'll be able to keep updating to the last version). As I want to save a circular image, I need the following : -A circular overlay (can be extremely easily with configuration block of the controller) -On the second screen, be able to crop the image with a circular overlay (like this : [login to view URL]) without loosing benefit of DBCamera (Image filters) Requirements : -The way we can launch the cameraViewController and get the image should be as easily as it is with DBCamera. -Should be compatible with iPhone AND iPad (except if DBCamera is not compatible with iPad) -Should be working using a swift project (only the call to the controller, you DON'T have to rewrite DBCamera in Swift) -Should be working on iOS 7 & 8 Please understand that the requirements are already filled with DBCamera, so it ONLY requires you to do the adaptation with this in mind. As it is very easy to add a view on the firstController, the best thing is probably to add a functionality to DBCamera which forces a circular crop !!!!!!!! Happy bidding guys. PS : If you are able to provide very clean code, I may have a lot of work for you ;)
