Question

I wish to drag from one subview to another within my application (and connect them with a line), and so I need to keep track of the current view being touched by the user.

I thought that I could achieve this by simply calling [UITouch view] in the touchesMoved method, but after a quick look at the docs I’ve found out that [UITouch view] only returns the view in which the initial touch occurred.

Does anyone know how I can detect the view being touched while the drag is in progress?

Answer 1

After a bit more research I found the answer.

Originally, I was checking for the view like so:

if([[touch view] isKindOfClass:[MyView* class]])
{
   //hurray.
}

But, as explained in my question, the [touch view] returns the view in which the original touch occurred. This can be solved by replacing the code above with the following:

if([[self hitTest:[touch locationInView:self] withEvent:event] isKindOfClass:[MyView class]])
{
    //hurrraaay! :)
}

Hope this helps
