title: iOS Save the top number from a label.
body: <p>So I have this app that tracks your speed and altitude. I have a UILabel that shows the current speed you are at and the current altitude you are at. What I want to do is have a label that shows the max altitude and the max speed. So basically if you are running and your speed reaches 5 mph the max label will say 5 mph and then if you get to 6 mph the max label will change to 6 etc... Same thing for the altitude label. So how do I do this?</p>
