The following classes are available globally.
This is a “spinner” control, which acts a bit like a circular UIPickerView.
However, instead of having the values provided by a delegate/datasource, the values are associated directly with the control in an Array.
This control has a lot of “little things” to make it usable and intuitive. It has “inertia,” where you can start it spinning, it has “one-tap increment/decrement,” and it has haptic and audio feedback.
It can switch between the circular spinner, and a standard UIPickerView, if there are too many items to handle efficiently in a spinner. You can choose to either always use the picker, or never use the picker.
There is a delegate protocol, and the control will also emit “valueChanged” messages (the selected item changed), and “touchUpInside” messages (the center was tapped).See more
