Implicit conversion from enumeration type 'UIInterfaceOrientation' to different enumeration type 'UIDeviceOrientation'

Question

I am getting the above compiler warning for the code below. I understand the difference between Interface and Device orientation, but am unsure how to amend to remove the warning. Can anyone help ?

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
if (ViewController != NULL) {
    [ViewController configureForDeviceOrientation:toInterfaceOrientation];
}
if (Controller != NULL) {
    [Controller configureForDeviceOrientation:toInterfaceOrientation];
}
currentOrientation = toInterfaceOrientation;
}

Answer 1

just cast it [Controller configureForDeviceOrientation:(UIDeviceOrientation)toInterfaceOrientation];

Answer 2

Your method configureForDeviceOrientation: is expecting to be passed a UIDeviceOrientation enum and not a UIInterfaceOrientation which you are passing in.

If you correct your method to accept a UIInterfaceOrientation from the willRotateToInterfaceOrientation: method, then you'll resolve the issue.
