Question

Im writing an app that I would like to display different views based on orientation. For example, if the device is portrait load pView, if landscape load lView. Below is the code ive currently tried.

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)
interfaceOrientation duration:(NSTimeInterval)duration {
 if (interfaceOrientation == UIInterfaceOrientationPortrait)
{
      self.view = portrait;
}
 else if (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown){
      self.view = portrait;
 }
 else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight){
      self.view = portrait;
 }
 else if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft){
      self.view = landscape;
 }

}

With this I have created 2 views in IB and connected the outlets to the right view. Ive also tried this:

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)
interfaceOrientation duration:(NSTimeInterval)duration {
 if (interfaceOrientation == UIInterfaceOrientationPortrait)
{
      self.view = portrait;
}
 else if (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown){
      self.view = portrait;
 }
 else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight){
      lView *abo = [[lView alloc] initWithNibName:@"lView" bundle:nil];
      [self.navigationController pushViewController:abo animated:NO];
      [abo release];

 }
 else if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft){
      lView *abo = [[lView alloc] initWithNibName:@"lView" bundle:nil];
      [self.navigationController pushViewController:abo animated:NO];
      [abo release];

 }

}

The code directly above worked for ipod but not ipad. Any ideas?

I found the following 2 (Apple) sample projects useful:

Also, remember from a device perspective there is also face-up and face-down orientations; this caught me out.
