You can't pause a timer. However, when the user goes to the settings view, you can save the fireDate of the timer and also the current date. After this you invalidate the timer and let the user do his/her stuff. Once he/she switches back to the game, you create a new timer object and set the fire date to the old fire date plus the time the user was in the menu (oldTime + currentTime).
