Question

In my app I have multiple views, some views need to support both portrait and landscape, while other views need to support portrait only. Thus, in the project summary, I ha

Answer 1

If you are using UINavigationController, you have to implement shouldAutorotate and supportedInterfaceOrientations in subclass of UINavigationController.

These are able to control by two steps, if shouldAutorotate returns YES then effective supportedInterfaceOrientations. It's a very nice combination.

This example, my mostly views are Portrait except CoverFlowView and PreviewView. The CoverFlowView transfer to PreviewView, PreviewView wants to follow CoverFlowCView's rotation.

@implementation MyNavigationController

-(BOOL)shouldAutorotate
{

if ([[self.viewControllers lastObject] isKindOfClass:NSClassFromString(@"PreviewView")])

return NO;

else

return YES;

}



-(NSUInteger)supportedInterfaceOrientations

{

if ([[self.viewControllers lastObject] isKindOfClass:NSClassFromString(@"CoverFlowView")])

return UIInterfaceOrientationMaskAllButUpsideDown;

else

return UIInterfaceOrientationMaskPortrait;

}

...
