user interface - How to still use iOS6 UI in iOS 7?

Question

From the transition guide from apple I know that there is no rounded rect button in iOS 7, but when I see many "old" apps that run in iOS 7 are still in iOS 6 style.

I have recently developed an app in iOS 6, everything is good. But after iOS 7 published, I have to change a lot UI, for example, the navigation bar and bar button item. But I really do not want to adopt iOS 7 style , but with my app, UI cannot adopt itself to iOS 6 . Even I use the iOS 6 SDK, and publish my app in iOS 7 in iPhone 5, it still use the iOS 7 style and looks terrible.

Any ideas and suggestions? Thanks

You can enforce iOS 6's UI in your app:

[[NSUserDefaults standardUserDefaults] setObject:@(YES) forKey:@"UIUseLegacyUI"]
