Landscape Screen shifted to right in 20px

Question

Hi guys.

I am trying to rotate the screen on the iphone. For example, First state of screen : is "Portrait". Then it calls "Landscape" screen. Following code is used for making Landscape screen :

- (void)viewDidLoad {
    [super viewDidLoad];
    [UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeRight;
    CGFloat angle = 90 * M_PI / 180;
    self.view.transform = CGAffineTransformMakeRotation(angle);
    self.view.center = [nRangeAppDelegate sharedAppDelegate].window.center;
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 20, 480, 44)];
    label.textAlignment = UITextAlignmentLeft;
    label.numberOfLines = 2;
    label.text = @"12345\n67890";
    [self.view addSubview:label];
}

But above code shifted to right in 20 px.

How to make 480x320 view at point 0,0 no shifting ?

Thanks in advance.

Answer 1

Your window is shifted because the appDelegate window is not centred on the screen as it is drawn below the status bar

Try this:

self.view.center = CGPointMake(160.0, 240.0);

You must make sure you are adding this view to a normal viewcontroller (ie not a nav controller or similar). The easiest way to do this is to add it to the main application window, like so:

MyRoratedController *myCtrlr = [[MyRoratedController alloc] 
  initWithNibName:@"MyRoratedController" bundle:nil]; 
[window addSubview:[myCtrlr view]];

Note that if your app has a status bar shown you will have to change the 160 above to 150

My application navigation based application. All UIViewControllers have one UIView. When call the the view I am trying rotate, this code is used : MyRoratedController *myCtrlr = [[MyRoratedController alloc] initWithNibName:@"MyRoratedController" bundle:nil]; [navigationController pushViewController: myCtrlr animated:NO]; I've changed CGPointMake(160.0, 240.0) by many different values. But no changes. Please help. Guys. Thanks.
