How to detect iOS device programmatically

Question

I need to know which iOS device is currently running app (saying more exactly I need to know is device armv6 or armv7). UIUserInterfaceIdiomPad() could not check is device an iPhone4S or iPhone3G. Is it possible?

Just out of curiosity, why do you need to know whether it is armv6 or armv7? — Nick Bull, Jun 18 '12 at 11:34
I've added some feature into my project, and it causes crashes on armv6 devices (iPhone3G). I know, that the problem is in processor's architecture, but could not figure out how to solve it yet. So I decided to make a switch which turns off this feature on old devices while I'm trying to make app run on all devices — medvedNick, Jun 18 '12 at 11:45

Download https://github.com/erica/uidevice-extension (UIDevice-Hardware class) and you can use these:

[UIDevice currentDevice] platformType]   // returns UIDevice4GiPhone
[[UIDevice currentDevice] platformString] // returns @"iPhone 4G"

Or check if its retina

+ (BOOL) isRetina
{
    if([[UIScreen mainScreen] respondsToSelector:@selector(scale)])
        return [[UIScreen mainScreen] scale] == 2.0 ? YES : NO;

    return NO;
}

Or check iOs version

+ (BOOL) isIOS5
{
    NSString *os5 = @"5.0";
    NSString *currSysVer = [[UIDevice currentDevice] systemVersion];

    //    currSysVer = @"5.0.1";
    if ([currSysVer compare:os5 options:NSNumericSearch] == NSOrderedAscending) //lower than 4
    {
        return NO;
    }
    else if ([currSysVer compare:os5 options:NSNumericSearch] == NSOrderedDescending) //5.0.1 and above
    {        
        return YES;
    }
    else // IOS 5
    {
        return YES;
    }

    return NO;
}

hmm you did not say that -platformString is an category for uidevice from [there](https://github.com/erica/uidevice-extension/) ;) – medvedNick Jun 18 '12 at 12:03

-1 `[[UIDevice currentDevice] platformString]` didn't work for me. – Stunner Jul 01 '12 at 05:36
I forgot to mention that you have to download this https://github.com/erica/uidevice-extension/ – Omar Abdelhafith Jul 01 '12 at 05:58

Revoked my -1 and edited your post to post the url at the top with the code block (more helpful at a glance that way). – Stunner Jul 06 '12 at 03:09

If you really want to know (at run time) if you are running on arm6 or arm7, you can use "NXGetArchInfoFromCPUType" (much more detail is available in the accepted answer to this question).

Otherwise you can use platformType or platformString, as our incredibly quick answering friend Omar suggested (and +1 to him!).
