I am creating an iOS application for a stock picking system. Customers will order in stock and use this system to go and find the item off the shop floor to pack. They submit through the system and have to input the quantity to pick - but before A/B testing wanted to see if anyone else has experience of this problem before.
- Solution one - Select quantity via UIPickerView Spinner:
- Solution two - Buttons:
Have already looked at Best way to select quantity of items for an eCommerce mobile application? but as this post is rather out of date, wanted to see what other opinions there were now, or any research into this topic.
If we implement the second style, we would also consider using swipe gestures to hide the 'None' and 'All' button, so users can just slide the buttons in and out of the screen, if the size of the buttons is an issue.
