Q: 

What user interface element would I use to take and crop a photo on the iPhone?

I'd like to be able to take a photo from the iPhone's camera, select a polygon within that photo, crop the photo to match, and then fit the resulting image to the screen.

What user interface element would you suggest for me to start doing this?

I'm a Java programmer and just getting started with the iPhone, so I'm not sure what to use.

+2  A: 

You should start by looking at sample code from Apple for UIImagePickerController to start getting the image. When you are comfortable with that you can start thinking about how to crop the image.

Hi, thanks for that. Should I use something based on OpenGL or just like that next to process image?

Also if you're comfortable, would you share some book for java/as3 developer to better understand cocoa/objective-c please? :)

Just read Programming in Objective-C 2.0.
