Is [UIScreen mainScreen].bounds.size becoming orientation-dependent in iOS8?

Question

I ran the following code in both iOS 7 and iOS 8:

UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
BOOL landsca         


        

Answer 1

My solution is a combination of MaxK's and hfossli. I made this method on a Category of UIScreen and it has no version checks (which is a bad practice):

//Always return the iOS8 way - i.e. height is the real orientation dependent height
+ (CGRect)screenBoundsOrientationDependent {
    UIScreen *screen = [UIScreen mainScreen];
    CGRect screenRect;
    if (![screen respondsToSelector:@selector(fixedCoordinateSpace)] && UIInterfaceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation)) {
        screenRect = CGRectMake(screen.bounds.origin.x, screen.bounds.origin.y, screen.bounds.size.height, screen.bounds.size.width);
    } else {
        screenRect = screen.bounds;
    }

    return screenRect;
}

Answer 2

Used slightly modified mnemia's solution, that one without iOS version check, using min/max on mainscreen bounds.
I needed a CGRect so got CGRect from mainscreen bounds and changed size.width=min(w,h), size.height=max(w,h). Then I called that OS-independent get CGRect function in two places in my code, where I getting screen size for OpenGL, touches etc. Before fix I had 2 problems - on IOS 8.x in landscape mode display position of OpenGL view was incorrect: 1/4 of full screen in left bottom part. And second touches returned invalid values. Both problems were fixed as explained. Thanks!

Just adding the swift version of an excellent cbartel function answered above.

func screenSize() -> CGSize {
    let screenSize = UIScreen.mainScreen().bounds.size
    if (NSFoundationVersionNumber <= NSFoundationVersionNumber_iOS_7_1) && UIInterfaceOrientationIsLandscape(UIApplication.sharedApplication().statusBarOrientation) {
        return CGSizeMake(screenSize.height, screenSize.width)
    }
    return screenSize
}

Answer 4

Yes, it's orientation-dependent in iOS8, not a bug. You could review session 214 from WWDC 2014 for more info: "View Controller Advancements in iOS 8"

Quote from the presentation:

UIScreen is now interface oriented:

• [UIScreen bounds] now interface-oriented
• [UIScreen applicationFrame] now interface-oriented
• Status bar frame notifications are interface-oriented
• Keyboard frame notifications are interface-oriented

Answer 5

Yes, indeed, screen size is now orientation dependent in iOS 8. Sometimes, however, it's desired to get a size fixed to portrait orientation. Here is how I do it.

+ (CGRect)screenBoundsFixedToPortraitOrientation {
    UIScreen *screen = [UIScreen mainScreen];

    if ([screen respondsToSelector:@selector(fixedCoordinateSpace)]) {
                    return [screen.coordinateSpace convertRect:screen.bounds toCoordinateSpace:screen.fixedCoordinateSpace];
    } 
    return screen.bounds;
}

Answer 6

Yes, it's orientation-dependent in iOS8.

I wrote a Util method to resolve this issue for apps that need to support older versions of the OS.

+ (CGSize)screenSize {
    CGSize screenSize = [UIScreen mainScreen].bounds.size;
    if ((NSFoundationVersionNumber <= NSFoundationVersionNumber_iOS_7_1) && UIInterfaceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation)) {
        return CGSizeMake(screenSize.height, screenSize.width);
    }
    return screenSize;
}
