Is there any way to make navigation bar elements (back button) in iOS 6 look like navigation bar elements in iOS 7 ? And also buttons and other iOS 7 elements of UI.

Change the Bar StyleA user changes the navigation bar's style, or UIBarStyle , by tapping the “Style” button to the left of the main page. This button opens an action sheet where users can change the background's appearance to default, black-opaque, or black- translucent.
A UINavigationBar object is a bar, typically displayed at the top of the window, containing buttons for navigating within a hierarchy of screens. The primary components are a left (back) button, a center title, and an optional right button.
macOS doesn't provide a navigation bar. To enable navigation in a macOS app, you often use a sidebar or a navigation control like a Back button in a toolbar. Also, you typically display the title of a macOS window in the title bar.
Instead of putting code into every view controller that you need to customize, I would recommend doing this for the entire application by putting something like this in your application:didFinishLaunchingWithOptions: method in the App Delegate
// Nav bar
[[UINavigationBar appearance] setBackgroundImage:[[UIImage imageNamed:@"navBar.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(10, 5, 10, 5)] forBarMetrics:UIBarMetricsDefault];
// Back buttons
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:[UIImage imageNamed:@"backNavButton.png"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
// Toolbar
[[UIToolbar appearance] setBackgroundImage:[[UIImage imageNamed:@"toolbar.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(10, 5, 10, 5)] forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault];
