statusBarOrientation deprecated

My apps use code to put objects on the screen and the layout of my apps changes depending on the orientation of the device. I had been using statusBarOrientation to determine the orientation, but it as been deprecated as of iOS 9. It still works in iOS 11 but since I have to update my apps anyway for iPhone X, I decided that now would be as good a time as any to update the code.

I believe the reason for the deprecation is that now apps can appear in a sidebar, so they don’t have a status bar. I have not enabled that behaviour in my apps, so it doesn’t affect me. The recommended way to get the orientation is to look at the screen size.

I had been using this line at the top of each file where I needed to do something depending on orientation.

 UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;

I use a utilities class for things that I use across classes, so I decided to put it there so I could change it easily if I needed to at some point in the future.

+ (NSString *) orientation  {

    CGSize screenSize = [UIScreen mainScreen].bounds.size;
    NSString *deviceOrientation = @"Portrait";
    if (screenSize.height < screenSize.width) {
        deviceOrientation = @"Landscape";
    return deviceOrientation;

The replacement code in each class is:

NSString *orientation = [Utilities orientation];

The enum UIInterfaceOrientation has not been deprecated, so I could have returned one of the values and not had to change any other code, but the conditionals are messy and hard to read,

if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown)

so I decided to return a string instead to make the code easier to read, e.g.

if ( [orientation isEqualToString:@"Portrait"] ) {
