How to set device orientation programmatically in iOS

I have a ebook reader app where in, i need to programmatically adjust the device orientation according to the layout of the page... i.e, The device should support all orientations for some pages and only landscape for some other pages. Is there anyway in which i can force a orientation change programatically

NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationLandscapeRight];
[[UIDevice currentDevice] setValue:value forKey:@"orientation"];

This can set the device orientation to LandscapeRight programmatically.

This works for me on Xcode 6 & 5.

- (BOOL)shouldAutorotate {return YES;}
- (NSUInteger)supportedInterfaceOrientations {return (UIInterfaceOrientationMaskPortrait);}

Note that the behavior for this has changed as of iOS 6.0. For further info, see: Autorotate in iOS 6 has strange behaviour

The gist is that should/will/did/etc have been deprecated and have been replaced with a cleaner, more dynamic implementation. Which we should all be thankful for.

Actually you can force any rotation. At least I was able to do it. Solution I used: https://stackoverflow.com/a/10146270/894671

You can use the answer from jbat100 plus a call to setStatusBarOrientation:animated in UIApplication to achieve the effect.

You cannot force the device orientation to some value, the system tells you the device's orientation, not the opposite. You can rotate your views using CGAffineTransform and such (a related post here).
