Question

I just discovered that if I do the following:

1. Click the button that animates a UIPickerView into my view
2. Quickly start the wheel rolling towards, then past, the last item
3. Dismiss the view with a button

Then it has not yet selected the last item yet.

I tried this by simply outputting to the console whenever the didSelectRow method was fired, and it fires when the wheel stabilizes on the last item.

Can I detect that the wheel is still rolling, so that I can delay checking it for a selected value until it stabilizes?

If it matters, I’m programming in MonoTouch, but I can read Objective-C code well enough to reimplement it, if you have a code example that is.

Answer 1

I think you can just check if the UIPickerView is in the middle of animating and wait for it to stop. This was answered here link
