A:
I think you might be looking for CGContextBeginPath and its related functions. I am not quite sure how to define a new stroke but I imagine it can be handled with something like [UIColor colorFromImage:myImage]. You should look into Quartz 2D, try looking here.

It's not going to be a walk in the park. You should be able to make a custom pen (stroke) somehow using the Quartz 2D API. If you cannot find the functionality in the API for that, my best guess would be that you can load an image (round white for chalk) and continuously paint it to the image when a user touches the image. You are going to have to use `touchesBegan:withEvent:` on an UIResponder or you can make a Gesture Recognizers: http://developer.apple.com/iphone/library/documentation/EventHandling/Conceptual/EventHandlingiPhoneOS/GestureRecognizers/GestureRecognizers.html
