iPhone UI Design approach - was using Excel Filtering

开发者_如何学CI'm new to iPhone development and don't know what the best iPhone UI approach for my problem is. That's where I was hoping you all could provide some input and guidance.

Here's the system & how it's currently used:

Right now, I have an Excel spreadsheet of data with four columns - Make, Model, Size, Value. There are about 1,000 rows of data. How the system is used in Excel is to use Filtering on the columns. First, you select the Make from the filtered column (there are about 8 unique Makes), then select a Model (each Make has between 1 and 20 unique Models), then select the Size (each Model has about 20 unique Sizes), then use the associated Value.

If I were to create an HTML page and jQuery with AJAX, I'd have three SELECT elements and one DIV (or some kind of label). When a Make is selected, populate the Models SELECT. Likewise, when a Model is selected, populate the Size SELECT. Finally, when a Size is selected, display the associated Value in the DIV. (Note, that when a Make is selected, I'd need to clear out the Value DIV and the Size SELECT in addition to the population of the Model SELECT. - appropriate action for selecting Size as well)

Now, given that, what do you recommend as a UI pattern for the iPhone?

You could do exactly that you describe for the HTML version, using a UIPickerView in each place where you would use and HTML SELECT. (The UIPickerView uses the "spinning wheel" metaphor to select from a list of values).

You could also use a single multi-component UIPickerView, where the first wheel is Make, the second Model, and the third Size. That works best if the names are short enough that you can fit all three (Make/Model/Size) in a single row on the screen.
