How to call shouldAutorotateToInterfaceOrientation manually?

Content of this function has on/off flag, so when I change this flag, I need to rotate screen.

Example:

1. Disable flag
2. Tilt phone in horizontal position. shouldAutorotateToInterfaceOrientation called and returns false
3. Enable flag: shouldAutorotateToInterfaceOrientation must be called. How to call it?

Answer 1

If you are targeting iOS 5, you can call

[UIViewController attemptRotationToDeviceOrientation]

which will call shouldAutorotateToInterfaceOrientation: with the device’s current orientation and will rotate the interface if that method returns YES.
