UISplitViewController and orientation - iOS < 5.0

Question

I am using a splitviewcontroller as the rootview of my application. I need to show the login and registration views as a modal view on top of the splitviewcontroller. When i

Answer 1

If I remember correctly, iOS misreports the actual orientation until the first rotation.

Also IIRC, using [[UIApplication sharedApplication] statusBarOrientation] circumvents this problem.

Answer 2

After removing the login view from the window set the rootviewcontroller direction according to the orientation of device using following code.

#define DegreesToRadians(x) ((x) * M_PI / 180.0)

[LoginviewContoller.view removeFromSuperview]

self.viewController = [[[ExampleViewController alloc] initWithNibName:@"ExampleViewController" bundle:nil] autorelease]; 

switch(self.viewController.interfaceOrientation)

{ 
case UIInterfaceOrientationPortrait:             
    NSLog(@"potrait");            
    break;
case UIInterfaceOrientationPortraitUpsideDown:
    NSLog(@"prtraitdown");
    break;
case UIInterfaceOrientationLandscapeLeft:
    self.viewController.view.transform =  
    CGAffineTransformMakeRotation(DegreesToRadians(270));
    NSLog(@"lanscapelef");
    break;
case UIInterfaceOrientationLandscapeRight:
   self.viewController.view.transform = CGAffineTransformMakeRotation(DegreesToRadians(90));
   NSLog(@"landcsape righ");
   break;
}

[self.window addSubview:self.viewController.view];

It will load the Rootviewcontroller according to the device orientation.
