iOS pickerWheels: Slow ‘mobile:selectPickerWheelValue’ example

If .setValue() fails then mobile: selectPickerWheelValue helper
could be used as a workaround.

This mobile method allows to select the next or the previous picker
value.

It is necessary to keep changing picker wheel values until the current
one is equal the desired one or the count of retries exceeds.
