Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
I would like to set up a view controller with a 2-component picker where each side contains the same 7 objects. Each object carries the same value for both components. The user would make a selection from each side, enter a value in a provided text field (and optionally tap a "Calculate" button). A calculation would occur using that value and the values from the two picker component objects that were selected and the results would be displayed in a label.
For example, each picker contains the letters a - g. Each letter carries the value of 1 - 7 respectively, for each side of the picker. The user selects "b" and "d" and enters 10. The calculated result of 10 * 2 / 4 = 5 is displayed.
It sounds simple enough. I've found tutorials for doing calculations using values associated with a 1-component picker as well as working with 2-component pickers, but nothing for doing calculations with 2-component pickers. My experience with Xcode is somewhat short. I have solved many problems by following related examples and modifying them to do what I need. So, please be gentle.
