I'm trying to create something similar to a piano where there are keys next to each other that should respond when a touch is dragged across them.
I have it working with an outter controller that does a hittest on all it's children to find the key that is hit, but I'm trying to see if I can avoid that by detecting the touches and drag directly in the individual controllers for each key. I have a button in each of these views but the problems are: 1) The button hit area is much larger than the button itself, so UIControlEventTouchDragExit doesn't get called until the touch is far outside of the actual button graphic. 2) UIControlEventTouchDragEnter doesn't ever get called unless I touch down on a button, out of it, and back in. In other words if I touch down on one button and drag over another, the UIControlEventTouchDragEnter doesn't get called on the button i just dragged into. I also tried detecting the touches in the view controller using touchesBegan, etc and programatically set the button as highlighted so that it appears selected, but then I can't detect when the touch has exited the view on a drag. Any ideas on the best way to do this?
