2,030 PointsSwipable Buttons?
Im creating a calculator app and would like to make a multi function button. One where you could swipe up or down for alternate functionality. How would i do that. Also, when you swipe up or down, the title should change as well.
Thanks

You could accomplish this by adding a panGestureRecognizer to your button (the easiest way to do this would be to do it in interface builder). Then you would link it to an @IBAction in your code, where you would determine the direction of the swipe, and do some calculation and/or change the text on the button.
Let me know if this gives you enough to get started!

39,020 PointsIf you can get more specific with what you're having trouble with, I might be able to help.
Take a look at this tutorial, which includes more or less exactly what you're looking for, I think: http://www.avocarrot.com/blog/implement-gesture-recognizers-swift/
