Question

I am registering my viewcontroller for UIDeviceOrientationDidChangeNotification and it’s return wrong orientation of device.
I am registering it in init function of viewcontroller

[[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(handleOrientationChangeNotification:) name: UIDeviceOrientationDidChangeNotification object: nil];

This is my device Notification Receiver method.

-(void)handleOrientationChangeNotification:(NSNotification *)notification
{ 
    if(IS_IPHONE)
    {
        UIDeviceOrientation currentDeviceOrientation =  [[UIDevice currentDevice] orientation];
    .
    .
    .
}

Whenever Device Orientation changed,I am always getting wrong orientation.

Answer 1

I find the solution on apple site on this link

UIDeviceOrientationLandscapeRight is assigned to UIInterfaceOrientationLandscapeLeft and UIDeviceOrientationLandscapeLeft is assigned to UIInterfaceOrientationLandscapeRight. the reason for this is that rotating the device requires rotating the content in the opposite direction.
