Frame movement question

Hey all, 2 questions here:

My game is for iOS (iphone, ipad). The game uses the click team movement controller and jumps the character in the game using a vector jumping system that retrieves jump info from a user generated vector (angle, power.) I want the frame to always center around the character. I want to start the frame zoomed in on him but to zoom out then zoom back in while the jump is occurring (at a rate dependent on how long the jump lasts). I also want the user to have the ability to zoom in and out using the iOS method (2 finger pinch.) For the zoom in zoom out during the jump, I was thinking some sort of fastloop that zooms out at some rate until the user reaches zero upward velocity, and zooms in to the original zoom level during downward velocity. Is this a good idea? Can someone help me put this together? Also, how do I control the frame zoom level using the iOS zoom in zoom out method? Is there an object for that that comes with the iOS extension?
