if you mean a mob spawner, which has a pig on fire in a cage block, you have to set the game difficulty to easy, normal, or hard. it will spawn mobs about every 21 seconds in a 9x9x9 area if there is a logical place to spawn a mob. if there are no logical places to spawn a mob, it will spawn nothing until an area opens up.
