+====== Automatically update the screen orientation ======
+//Here's a very useful code-snippet from this [[http://forum.sparrow-framework.org/topic/interface-orientation-solution|forum thread]]. Thanks, Arend!//
+One great thing about the iDevices is that you can detect the orientation of the screen and rotate the content accordingly. Here is a way to do it in Sparrow.
+In the ApplicationDelegate do this:
+<code objc>
+- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation
+{
+    return YES;
+}
+</code>
+In the SPStage class, in it's initWithWidth: Height: method add this:
+<code objc>
+[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
+[[NSNotificationCenter defaultCenter] addObserver:self
+    selector:@selector(onOrientationDidChange:)
+    name:@"UIDeviceOrientationDidChangeNotification" object:nil];
+</code>
+and add another method in this class:
+<code objc>
+-(void)onOrientationDidChange:(UIEvent *)event
+{
+    NSLog(@"%i", [UIDevice currentDevice].orientation);
+}
+</code>
+Whenever the device is now turned, the ''onOrientationDidChange''-method gets called, and you can update the screen accordingly within this method.
