Filtered Images

Instructions

1. Open up the project! We are going to filter an image of my friend Mickey climbing up a mountain. I took this with my iPhone so it's just a regular picture that a anyone could take. You'll notice it is a jpg. To deal with jpgs we have to use the fullname of the file when you grab the UIImage.
2. There are three buttons. Using the UIImage + Filters category provided, filter the image wtih the approprite filter for the button tapped. BTW This is just a category on UIImage that uses the filters built into iOS 7. Das (a former student who created this) didn't actually write crazy image filters.
3. You'll notice it's a biiiiit slow. Definitely blocks the main thread. Go ahead and dump that on a background queue.
4. Add in a Loading screen with MBProgressHUD.

Make it Right

1. To be honest this is a bit overkill for such a small background operation...but go ahead and make an NSOperation Subclass and put the operation in the subclass.
