I had a few problems grasping this chapter, but i guess the points i’m feeling are a little blurry will clear up after practice and more reading in further chapters. I won’t go as far as to re-read the entire chapter… yet
anywhoo, i don’t at all understand why we must make an NSTimeInterval, and check if the data is more than 3 minutes old? the method is called when a new location is found, and we only look for a new location when we press the return key on our keyboard (or move 20 meters, or whatever limit we set). So, why would it have to do that check?
