如果我使用iOS7 SDK进行构建，则我的应用在旧设备上会具有新外观吗？

Question

I'm finally updating my iOS app to build with Xcode 5 and iOS7 SDK. I see this gives my app a new look (white, no border on buttons, etc). I don't have iOS6 available for easy testing, so I'm asking here.

Will my app have the new look when run on older devices, or still the old look?

I hope it doesn't have a different look on different devices, that will be a pain to design for (ie-make sure buttons/colors/spacing/etc are all optimized for each look). I do notice a lot of apps don't use many "native" elements like toolbars, tab strips, or native buttons, maybe this is why (keep the same look across all OS versions).

If you're using stock UI elements (provided by the Apple SDK), then on iOS 7 it will have the new look (iOS 7 look), and on iOS 6 it will have the old look (iOS 6 look).

While the colors / look may be a little different, the spacing shouldn't be too different.

If you wan't it to look the same on all OS versions, just use your own custom buttons etc, or customise the existing ones.
