Cocoa Touch - Drag onto button to trigger event

Question

Hey all, just wondering what the best way to add this capability was.

I want to be able to press the button normally by doing touchDownInside, but I also want to be able to slide my finger from one button to the next and have the next one trigger.

How can I do that?

Ex:

(-) -> (-)
^Buttons^

Answer 1

You can implement touchesEnded method and check if the touch point is within any of your button's frames..
