Thanks for the code.
I think class methods are better, to avoid class instantiation:

  • (NSString *) platform;
  • (NSString *) platformString;

And change:
NSString *platform = [self platform];
by
NSString *platform = [UIDeviceHardware platform];

Now usage is easier and more elegant

It seems to me this may be accessing private data of the phone - meaning non public framework apis. Has anyone got this into the app store ?

Aso, if anyone still wonders, all of this code uses public API. Personal data != private API.

hi
Can someone clarify how i can use this above code.
I am still learning xcode quickly but this confuses me as i dont know where to put it.
I dont get any errors i have just tried using NSLOG to tell me what platform is connected but it doesnt work as i cannot call the NSString platform.
I basicallt want to set variables so my program knows what device is connected.
Any help would be great
thanks
clive

Two enhancements.

  1. According to the Mac OS X Manual Page For sysctl(3), "the sysctl() function runs in about a third the time as the same request made via the sysctlbyname() function." So, the following code is probably a bit faster because it uses sysctl() instead of sysctlbyname(), but I didn't test it.

    #include <sys/sysctl.h>
    
    NSString *AACPlatform()
    {
        int mib[] = {CTL_HW, HW_MACHINE};
        size_t len = 0;
        sysctl(mib, 2, NULL, &len, NULL, 0);
        char *machine = malloc(len);
        sysctl(mib, 2, machine, &len, NULL, 0);
        NSString *platform = [NSString stringWithCString:machine encoding:NSASCIIStringEncoding];
        free(machine);
        return platform;
    }
    
  2. You can make both Objective-C methods C functions since they don't access any instance variables.

I also see that the freebsd implementation of sysctlbyname uses syctl and sysctltomib.
(http://fxr.watson.org/fxr/source/gen/sysctlbyname.c?v=FREEBSD-LIBC).
Is Apple's implementation any different?

Jay - great code. It currently lacks a license and thus is technically protected and not something we can use in our code. Would you mind choosing a license? Most common licenses for these snippets and free code are MIT and BSD-type licenses which don't restrict usage.

I've attached a sample license you can reuse if that is your wish. You can add it in the header of your .h file or as a separate LICENSE.TXT file in the repo.

Are you 100% sure this is correct?

if ([platform isEqualToString:@"iPhone7,1"]) return @"iPhone 6+";
if ([platform isEqualToString:@"iPhone7,2"]) return @"iPhone 6";

Going by the trend for iPhone5,5s, it should have been:

if ([platform isEqualToString:@"iPhone7,1"]) return @"iPhone 6 GSM";
if ([platform isEqualToString:@"iPhone7,2"]) return @"iPhone 6 GSM+CDMA";

if ([platform isEqualToString:@"iPhone8,1"]) return @"iPhone 6+ GSM";
if ([platform isEqualToString:@"iPhone8,2"]) return @"iPhone 6+ Global";

what's the authoritative source for the model id? i see everymac.com has the model id, but do not see anything published by apple. has anyone seen anything from apple? is there a way to know without physically checking the devices?

Hi EvgenyKarkan,
I've allready released two games with this code. No problems with the approval.

I've done a little extension to do a numeric comparison for forthcoming devices. So for doing this check due to performance issues you can use this like "iPad Air" and later:

+ (int) deviceVersion:(NSString*) deviveType {

    NSString *platform = [self platform];
    int deviceVersion;

    if ([platform containsString:deviveType]) {
        NSString *platformSplit = [platform componentsSeparatedByString:@","][0];
        deviceVersion = [[platformSplit substringFromIndex: [platformSplit length] - 1] intValue];
    } 
    return deviceVersion;
}

so you can use it like this for example:

    int iPadVersion = [UIDeviceHardware deviceVersion:@"iPad"];
    int iPhoneVersion = [UIDeviceHardware deviceVersion:@"iPhone"];

    //iPad Air 2 and all upcoming devices in the future
    if (iPadVersion >= 5) {
        return true;
    }

    //iPhone 6 and all upcoming devices in the future 
    if (iPhoneVersion >= 7) {
        return true;
    }

Are you 100% sure this is correct?
if ([platform isEqualToString:@"iPhone7,1"]) return @"iPhone 6+";
if ([platform isEqualToString:@"iPhone7,2"]) return @"iPhone 6";

that is correct.
It was actually confirmed.

Going by the trend for iPhone5,5s, it should have been:
if ([platform isEqualToString:@"iPhone7,1"]) return @"iPhone 6 GSM";
if ([platform isEqualToString:@"iPhone7,2"]) return @"iPhone 6 GSM+CDMA";
if ([platform isEqualToString:@"iPhone8,1"]) return @"iPhone 6+ GSM";
if ([platform isEqualToString:@"iPhone8,2"]) return @"iPhone 6+ Global";

here is incorrect.

I performed some benchmarks, to test class methods vs instantiation and to check out @mattdipasquale comment re sysctl.

I used various implementations of my category. You can see I've added a few more methods to return a bit more info.

My benchmarking code was:

extern uint64_t dispatch_benchmark(size_t count, void (^block)(void));
size_t const iterations = 10000;
uint64_t tt = dispatch_benchmark(iterations, ^{
	@autoreleasepool {
                HKWUIDeviceHardware *h=[[HKWUIDeviceHardware alloc] init];
                 _deviceType = [h platformString];
		_isIpadOneOrTwo = [h isIpadOneOrTwo];
		_isSexSeven = [h isSixOrSeven];
		_isPlus = [h isPlus];
	}
});
NSLog(@"HKWUIDeviceHardware Avg. Runtime: %llu ns", tt);

Results - Simulator

Test Avg. Runtime (ns)
This gist 36580
This gist with sysctl 26186
Class methods 36338
Class methods with sysctl 25836
My version 9876

Results - iPhone 7

Test Avg. Runtime (ns)
This gist 18210
This gist with sysctl 17438
Class methods 25550
Class methods with sysctl 21496
My version 4563

Now, my implementations of the class method version may not have totally optimised, but they didn't have my extra methods either.

Taking the initial implementation vs my implementation:

Simulator: 36580/9876 = 3.70x faster
iPhone 7: 18210/4563 = 3.99x faster

The faster implementation (if your machine name length is limited) is this, which saves a heap allocation and caches the result.

static NSString *platform;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
    int key[] = { CTL_HW, HW_MACHINE };

    static size_t const maxSize = 32;
    size_t size = maxSize;
    char machine[maxSize];
    __unused int result = sysctl(key, 2, machine, &size, NULL, 0);
    NSAssert(result == noErr, @"Failed to get platform name. Error: %s", strerror(result));

    platform = @(machine);
});

return platform;
