The documentation on the pickerWheel states that it does not support scaling and I don’t see any controls to manage it’s width. Yes you can set the skin to be bigger, but I don’t see where that controls the widget size. I looked around my iPad to try and find pickerWheels that were bigger than 320 wide and I couldn’t find any. This may be by design to mirror what the native UI does. I tried to go into XCode and use a pickerWheel that wasn’t 320 wide and I couldn’t get it to work (Not a strong suit of mine in any stretch).
