Better than the old 'isIPad' test... if you need to get really particular, you can 'split' between landscape and portrait by replacing '&&' with '} else if' CGRect screenBounds = [[UIScreen mainScreen] bounds]; int screenHeight = screenBounds.size.height; int screenWidth = screenBounds.size.width; if (((screenHeight == 480)&&(screenWidth == 320))||((screenHeight == 320) && (screenWidth == 480))) { // iPhone 4 [BT_debugger showIt:self message:[NSString stringWithFormat:@"iDevice: %@", @"iPhone 4"]]; } else if (((screenHeight == 568)&&(screenWidth == 320))||((screenHeight == 320) && (screenWidth == 568))) { // iPhone 5 [BT_debugger showIt:self message:[NSString stringWithFormat:@"iDevice: %@", @"iPhone 5"]]; } else if (((screenHeight == 667)&&(screenWidth == 335))||((screenHeight == 335) && (screenWidth == 667))) { // iPhone 6 [BT_debugger showIt:self message:[NSString stringWithFormat:@"iDevice: %@", @"iPhone 6"]]; } else if (((screenHeight == 736)&&(screenWidth == 414))||((screenHeight == 414) && (screenWidth == 736))) { // iPhone 6+ [BT_debugger showIt:self message:[NSString stringWithFormat:@"iDevice: %@", @"iPhone 6+"]]; } else if (((screenHeight == 1024)&&(screenWidth == 768))||((screenHeight == 768) && (screenWidth == 1024))) { // iPad [BT_debugger showIt:self message:[NSString stringWithFormat:@"iDevice: %@", @"iPad Family"]]; } else if (((screenHeight == 1366)&&(screenWidth == 1024))||((screenHeight == 1024) && (screenWidth == 1366))) { // iPad Pro [BT_debugger showIt:self message:[NSString stringWithFormat:@"iDevice: %@", @"iPad Pro"]]; } Hope this helps someone. At the very least, it's annoying to type and tedious to keep it straight ;) Cheers! -- Smug

and we used to gripe about Android device fragmentation..... check out UITraitCollection http://makeapppie.com/tag/uitraitcollection/ http://blog.flatironschool.com/working-with-size-classes-in-code-with/ I came across it trying to deal with rotation. This would be a great method for BT to adopt and use in the BT core to deal with all these device sizes and more importantly - rotation.
