Handling autorotation for one view controller in iOS7

Question

I\'ve read many answers on SO but I can\'t seem to get autorotation working on iOS7.

I only need one view controller to rotate, so I don\'t want to set rotation sett

Answer 1

I know this is old but I ended up in a more unique situation where we have 50+ ViewController all over the app that I refused to go through and modify and support the same orientation in all of them but one or 2. Which brings me to my answer. I created a UIViewController category that overrides - (BOOL)shouldAutorotate to always return NO or YES depending on device type etc. (this can be done with supported interface orientations too). Then on the ViewControllers I wanted to support more then just portrait, I swizzled shouldAutorotate to return YES. Then forced the orientation change when the view is dismissed on the parent ViewControllers viewWillAppear method using:

[[UIDevice currentDevice] setValue:@(UIInterfaceOrientationPortrait) forKey:@"orientation"].

When all was said and done, I accomplished everything I wanted on a few ViewControllers with < 30 lines of code using a macro for swizzling. Had I done it by replacing shouldAutorotate and supportedInterfaceOrientations on all of the VC's in the application I would have ~250 extra lines of code. and a lot of grunt work adding it in the first place.
