Need suggestions to implement Orientation methods in iOS app

Question

I have implemented one universal iOS app for both iPad & iPhone that supports iOS6 & iOS7 in Portrait mode.
Now my new task is to support landscape mode for this app also.
These views are not Auto Layout enabled.

My question is, Is there any great solution for orientation instead of implementing all orientation methods and writing code in each UIViewController class?
I have used too many controls in each XIB file. Please make suggestions to me.

Autolayout is probably your best option. If you haven't been exposed to autolayout before I suggest reading a tutorial on RayWenderlich.com and watching the autolayout videos from the past 2 or three WWDC's. Several of the 'beginning autolayout' videos address the problem your facing.
