I have read this question about the differences in the window- and view-based iOS application templates in Xcode, but I'm still confused about what template to use in my iPhone app.
I am developing a geolocation app for service stations. What template would be more appropriate for this: the view-based application template or the window-based one?
The choice won't greatly affect your end product. The real question is what template gets me closest to the app I'm designing.
The view-based application template is geared towards an app with a single view. It's just a starting point, though, and you can always add more views/controllers to it afterwards. There's nothing special in the view-based template that you couldn't add to a window-based template, as shown in this blog post.
Your app sounds like it might benefit more from a navigation-based template. That will give you a UINavigationController and a UITableViewController to work with initially, and I'm guessing that would work well with your list of service stations. Perhaps when a service station is selected, you'd push a geolocalisation (sp?) view controller showing the details of the service station?
View-based Application description:
This template provides a starting point for an application that uses a single view.
If your app's design contains only a single view, then choosing View-based Application will save you the trouble of creating and linking that view. Even if your app has more than one view, View-based can still save you the time of making that initial view. You want Window-based Application for when you know you're setting up something custom.
