i have an app that perfectly work in iOS 6, and when i update my iPhone to iOS 7 that was still work fine.
Then i update my XCode, and made some minor changes in my app (i did hide 2 UINavigation back bar buttons). After that i update my app (i want to point that i didn't change interface of my app), and when i update it from appStore and launch it on my iPhone there was a completely disaster. Interface objects such as segmented control or UIDatePicker automatically changes for iOS 7 version (style, color), back bar button item change it style, etc.
My question is, how can i force my app to launch on iOS7 with previous (iOS 6) design?
