How to detect Orientation Change in Custom Keyboard Extension in iOS 8?

Question

In Custom Keyboard Extension , we can\'t use

`didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation` 

and

Answer 1

Non-deprecated and will work on any device screen size (including future screen sizes Apple will be releasing this year).

In CustomKeyboardViewController.m:

-(void)viewDidLayoutSubviews {
    NSLog(@"%@", (self.view.frame.size.width == ([[UIScreen mainScreen] bounds].size.width*([[UIScreen mainScreen] bounds].size.width<[[UIScreen mainScreen] bounds].size.height))+([[UIScreen mainScreen] bounds].size.height*([[UIScreen mainScreen] bounds].size.width>[[UIScreen mainScreen] bounds].size.height))) ? @"Portrait" : @"Landscape");
}

done.

Or..................

For a more easy to read version of this code:

-(void)viewDidLayoutSubviews {

    int appExtensionWidth = (int)round(self.view.frame.size.width);

    int possibleScreenWidthValue1 = (int)round([[UIScreen mainScreen] bounds].size.width);
    int possibleScreenWidthValue2 = (int)round([[UIScreen mainScreen] bounds].size.height);

    int screenWidthValue;

    if (possibleScreenWidthValue1 < possibleScreenWidthValue2) {
        screenWidthValue = possibleScreenWidthValue1;
    } else {
        screenWidthValue = possibleScreenWidthValue2;
    }

    if (appExtensionWidth == screenWidthValue) {
        NSLog(@"portrait");
    } else {
        NSLog(@"landscape");
    }
}
