Pardon me if I'm only using iOS terms. OK. First off, your UIButton needs to respond to UIControlEventTouchUpInside and also needs to respond to UIControlEventTouchDownRepeat.
Check out the UIControl Class Reference for the nature of the Touch Events you can respond to. You'll need a timer to and counter if you want to generate a faster FFWD if the button is held down longer. I had to do this while prototyping the FiOS TV GUI for Verizon a few years back. FFWD and RWD had modes that were the rate of the action. You'd go from 1x to 2x, 3x and 4x and then back to 1 again if you: Held the ffwd button down, released and pressed again within 350 ms. Holding down the button only started the FFWD/RWD mode and kept it active or advanced to the next FFWD/RWD level if pressed again within 350ms. Releasing the button did nothing to the rate. Pressing play was required to stop the action, back up 2.5 seconds and continue from that point. Make sure to think this through and work on a few models to make sure it's a clean functionality design.
