I would like to make a relatively simple iPhone Photo Cropping application.
Upon launching the app, the user is presented with the user's camera roll.
The user can select a photo and is brought into the cropping screen
The user can select from one of our pre-dertimined cropping ratios and move this selection around the screen
The user can also enter custom cropping ratios
Once the crop is in place, the user can crop the photo, and it is saved into the camera roll.
I don't think this will take an experienced coder more than 2-3 days tops.
Feel free to contact me for more details.
