iPhone + CGAffineTransFormRotate(pi/2) + statusBarHidden:YES + presentModalViewController = 20 pixels of white space

Question

I think the title is pretty descriptive:

I perform all 3 of these operations on a view, the result is 20 pixels of white space along the left side of the screen (if

I think you may need to recenter your center:

// Set the center point of the view to the center point of the window's content area.      
self.view.center = CGPointMake(160.0, 240.0);

This is the whole init method I use for landscape views and works without an issue. Just make sure to set your nib to the right size too.

// Implement viewDidLoad to do additional setup after loading the view.
- (void)viewDidLoad {
  [super viewDidLoad];

  // Rotate to landscape
  self.view.frame = CGRectMake(0, 0, 480.0, 320.0);
  if ([[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationLandscapeRight) {
    CGAffineTransform transform = self.view.transform;

    // Set the center point of the view to the center point of the window's content area.      
    self.view.center = CGPointMake(160.0, 240.0);

    // Rotate the view 90 degrees around its new center point.
    transform = CGAffineTransformRotate(transform, (M_PI / 2.0));
    self.view.transform = transform;
  }
