回答1:
Step 1. Create a subclass of UINavigationcontroller named like CustomNavController Step 2. initialise CustomNavController instead of UINavigationController in AppdDelegate.
Step 3. override following method of UINavigationController in CustomNavController
-(NSUInteger) supportedInterfaceOrientations
{
if([NSStringFromClass([[[self viewControllers] lastObject] class]) isEqualToString:@"ViewAsset"]){
return UIInterfaceOrientationMaskAll;
}
return UIInterfaceOrientationMaskPortrait;
}
-(BOOL)shouldAutorotate
{
return YES;
}
where ViewAsset is name of class which you need in both mode.

1) Select the "device orientations" that you want in your project from the "Deployment Info" in the "General" tab.
2) In your view controller class, use this code:
- (UIInterfaceOrientationMask) supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
3) For view controllers that you want to support both orientations:
- (UIInterfaceOrientationMask) supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscape;
}
