Detecting iPhone 6 6 screen sizes in point values

Question

Given the newly announced iPhone 6 screen sizes:

iPhone 6: 1334h * 750w @2x (in points: 667h * 375w)
iPhone 6+: 1920 * 1080 @3x (in points: 640h * 360w)

I was wondering if there is code that allows me to detect which screen size the user's device is, so that I could adjust and size UIImages and other materials accordingly with the user's device.

So far, I have been using the following:

- (NSString *) platform{
    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *machine = malloc(size);
    sysctlbyname("hw.machine", machine, &size, NULL, 0);
    NSString *platform = [NSString stringWithUTF8String:machine];
    free(machine);
    return platform;
}

- (NSString *) platformString{
    NSString *platform = [self platform];
    if ([platform isEqualToString:@"iPhone1,1"])    return @"iPhone 1G";
    if ([platform isEqualToString:@"iPhone1,2"])    return @"iPhone 3G";
    if ([platform isEqualToString:@"iPhone2,1"])    return @"iPhone 3GS";
    if ([platform isEqualToString:@"iPhone3,1"])    return @"iPhone 4";
    if ([platform isEqualToString:@"iPhone3,3"])    return @"Verizon iPhone 4";
    if ([platform isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";
    if ([platform isEqualToString:@"iPhone5,1"])    return @"iPhone 5 (GSM)";
    if ([platform isEqualToString:@"iPhone5,2"])    return @"iPhone 5 (GSM+CDMA)";
    if ([platform isEqualToString:@"iPhone5,3"])    return @"iPhone 5c (GSM)";
    if ([platform isEqualToString:@"iPhone5,4"])    return @"iPhone 5c (GSM+CDMA)";
    if ([platform isEqualToString:@"iPhone6,1"])    return @"iPhone 5s (GSM)";
    if ([platform isEqualToString:@"iPhone6,2"])    return @"iPhone 5s (GSM+CDMA)";
    if ([platform isEqualToString:@"iPod1,1"])      return @"iPod Touch 1G";
    if ([platform isEqualToString:@"iPod2,1"])      return @"iPod Touch 2G";
    if ([platform isEqualToString:@"iPod3,1"])      return @"iPod Touch 3G";
    if ([platform isEqualToString:@"iPod4,1"])      return @"iPod Touch 4G";
    if ([platform isEqualToString:@"iPod5,1"])      return @"iPod Touch 5G";
    if ([platform isEqualToString:@"iPad1,1"])      return @"iPad";
    if ([platform isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";
    if ([platform isEqualToString:@"iPad2,2"])      return @"iPad 2 (GSM)";
    if ([platform isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";
    if ([platform isEqualToString:@"iPad2,4"])      return @"iPad 2 (WiFi)";
    if ([platform isEqualToString:@"iPad2,5"])      return @"iPad Mini (WiFi)";
    if ([platform isEqualToString:@"iPad2,6"])      return @"iPad Mini (GSM)";
    if ([platform isEqualToString:@"iPad2,7"])      return @"iPad Mini (GSM+CDMA)";
    if ([platform isEqualToString:@"iPad3,1"])      return @"iPad 3 (WiFi)";
    if ([platform isEqualToString:@"iPad3,2"])      return @"iPad 3 (GSM+CDMA)";
    if ([platform isEqualToString:@"iPad3,3"])      return @"iPad 3 (GSM)";
    if ([platform isEqualToString:@"iPad3,4"])      return @"iPad 4 (WiFi)";
    if ([platform isEqualToString:@"iPad3,5"])      return @"iPad 4 (GSM)";
    if ([platform isEqualToString:@"iPad3,6"])      return @"iPad 4 (GSM+CDMA)";
    if ([platform isEqualToString:@"iPad4,1"])      return @"iPad Air (WiFi)";
    if ([platform isEqualToString:@"iPad4,2"])      return @"iPad Air (Cellular)";
    if ([platform isEqualToString:@"iPad4,4"])      return @"iPad mini 2G (WiFi)";
    if ([platform isEqualToString:@"iPad4,5"])      return @"iPad mini 2G (Cellular)";
    if ([platform isEqualToString:@"i386"])         return @"Simulator";
    if ([platform isEqualToString:@"x86_64"])       return @"Simulator";
    return platform;
}

As such, should I assume iPhone7,1 and iPhone7,2 are the iPhone 6 while iPhone7,3 and iPhone7.4 are the pluses? If anyone has more concrete way to tell it'd be great, thanks.!

Answer 1

The device screen will be the first screen, but new phones require launch pictures to be added first; otherwise, older apps will run in Zoomed Mode: The code I used to check this out is shown below. Note that iOS 8 and later is required for this to function.

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:

#define IS_PAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
#define IS_PHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)

-(BOOL)iPhone6PlusDevice{
    if (!IS_PHONE) return NO;
    if ([UIScreen mainScreen].scale > 2.9) return YES;   // Scale is only 3 when not in scaled mode for iPhone 6 Plus
    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;
}

Relying on.nativeScale will not work if you are adjusting the user interface for the iPhone 6 Plus since the results from the simulator and the actual device differ. because of the remark underneath. Due to the fact that scale is a CGFloat, programmes shouldn't check for equality since some float values may never be equal.

The new iPhone sizes can be used after installing Launch Screen; otherwise, your app will still seem scaled.

When compared to the iPhone 4, the iPhone 5 has a resolution of 640 x 1136.

Upload LaunchImages to avoid the programme running scaled and failing to display proper scaling or screen sizes.
