How to make automaic changes in the Orientation?

Question

I want to change the Orientation according to my application so how i can do this.Actually i am new in this field.

Answer 1

Include the following in your UIViewController:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return YES;
}

Edit: If you want to limit the orientations that are acceptable, instead of return YES; You can use return UIInterfaceOrientationLandscapeLeft | UIInterfaceOrientationPortrait; for example.
