How can I detect whether a user has an iPhone 6 Plus in standard or zoomed mode?

Question

How can I detect whether a user has an iPhone 6 Plus in standard or zoomed mode? Is this possible?

I\'ve tried [UIScreen mainScreen].scale and it report

Answer 1

The following code may be used to get bounds, coordinateSpace, nativeScale and scale, i.e. on an iPhone 6 Plus the nativeScale is 2.608 and when the device in run in Zoomed Mode it is 2.88 (note that it is different in the simulator):

UIScreen *mainScreen = [UIScreen mainScreen];
NSLog(@"Screen bounds: %@, Screen resolution: %@, scale: %f, nativeScale: %f",
          NSStringFromCGRect(mainScreen.bounds), mainScreen.coordinateSpace, mainScreen.scale, mainScreen.nativeScale);

Code for detecting iPhone 6 Plus:

-(BOOL)iPhone6PlusDevice{
    // Scale is 3 currently only for iPhone 6 Plus
    if ([UIScreen mainScreen].scale > 2.9) return YES;
    return NO;
}

or

 -(BOOL)iPhone6PlusUnZoomed{
        if ([self iPhone6PlusDevice]){
            if ([UIScreen mainScreen].bounds.size.height > 720.0) return YES;  // Height is 736, but 667 when zoomed.
        }
        return NO;
    }

Note: If you are checking for iPhone 6 Plus, to adjust the user interface then don´t rely on .nativeScale, because the simulator and an actual device give different results.
