How to check in which position (landscape or portrait) is the iPhone now?

I have an app with a tab bar, and nav controllers in each tab. When user shakes the device, a UIImageView appears as a child view in the nav controller. But the UIImageView must contain a special image, depending on the device's current orientation.

If I write just

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)
   if (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { 
   //Code
   }
   else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight||interfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
   //Code
   }
}

The view just goes crazy if user rotated the device before shaking.

Is there a method to get iPhones current orientation?

Solution 1:

Here are macros UIDeviceOrientationIsLandscape and UIDeviceOrientationIsPortrait

so rather checking separately you can do it like this ...

if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation))
{
    // code for landscape orientation      
}

OR

 if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation))
 {
     // code for Portrait orientation       
 }

Solution 2:

Use the [[UIDevice currentDevice] orientation] method, as specified here.
