iOS: How do I figure out the current orientation in viewWillAppear?

Question

I have a UIWebView that I would like to load different URLs depending on whether its portrait or landscape. How can I figure out what my current orientation is inside viewWillAppear?

Answer 1

Use UIApplication's statusBarOrientation property. You may run into problems if you use the device orientation if it is UIDeviceOrientationFaceUp or UIDeviceOrientationFaceDown.

Example

UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
if (UIInterfaceOrientationIsLandscape(orientation))
{
   // Do something when in landscape
}
else
{
   // Do something when in portrait
}

Answer 2

UIDeviceOrientation getCurrentOrientation() {
  UIDevice *device = [UIDevice currentDevice];
  [device beginGeneratingDeviceOrientationNotifications];
  UIDeviceOrientation currentOrientation = device.orientation;
  [device endGeneratingDeviceOrientationNotifications];

  return currentOrientation;
}

It's up to you to convert the UIDeviceOrientation to UIInterfaceOrientation.
