Well short answer to you question is YES; 

Long is :- If you user XCode 4.5 and build app that is universal the NIB files and Classes would work perfectly for Iphone 4 and Iphone 5; Understand for you it important to know the version of SDK of these mobiles not the mobile version them self.

Another thing is that iphone 5 size is little bigger then iphone 4 so you need to design accordingly.. please read my answer at <a href="https://stackoverflow.com/questions/12525200/iphone-5-screen-resolution-issue/12597403#12597403">Iphone 5 screen resolution issue</a> for better understanding.

Yes, you can use the same XIB to design for iPhone 4 and iPhone 5 by using Auto-Layout.

Build an app using iOS 6 as the Base SDK and use the Auto Layout feature to make screens that can scale for all type of screens. You'll need Xcode 4.5 to do this.

Get started with Auto Layout here:

blocks|key|465477|text|使用AutoAutoresizing，这样你就可以让应用程序与iOS+5和iOS+6兼容。如果你的布局具有最小的依赖性，这很容易。这对于修复像UIToolBar这样的组件的问题是可能的。iPhone+5中的按钮。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|465478|entityMap^0|2|G|1Z|9|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

Use <code>AutoAutoresizing</code> so that u can make app compatible with both iOS 5 and iOS 6. This is easy if your layout is having minimum dependancies. And this is possible for fixing issues with components like <code>UIToolBar</code>. Buttons in iPhone 5.

blocks|key|249034|text|添加名为Default-568h@2x.png的镜像。这将标识您的应用程序为支持iPhone+5指标的应用程序。此外，您还需要正确地自动调整视图大小。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|249035|​|249036|📷|atomic|offset|length|249037|249038|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://ask.qcloudimg.com/http-save/yehe-900000/a4b2244cfaced10dd086d75ad3312c16.png|imageAlt^0|0|0|0|1|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|T|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|U|8|@]|9|@$G|V|H|W|1|X]]|A|$]]|$1|I|3|C|5|6|7|Y|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|Q|R|-4]]]]

Add a image named Default-568h@2x.png. That will identify your app as one that supports iPhone 5 metrics. And also you need to do auto sizing of your views properly.
