Determine device (iPhone, iPod Touch) with iPhone SDK
Is there a way to determine the device running an application. I want to distinguish between iPhone and iPod Touch if possible.
Please feel free to use this class (gist @ github)

UPDATE (01/14/11)
Obviously, this code is a bit out of date by now, but it can certainly be updated using the code on this thread provided by Brian Robbins which includes similar code with updated models. Thanks for the support on this thread.
- (BOOL)hasRetinaDisplay { NSString *platform = [self platform]; BOOL ret = YES; if ([platform isEqualToString:@"iPhone1,1"]) { ret = NO; } else if ([platform isEqualToString:@"iPhone1,2"]) ret = NO; else if ([platform isEqualToString:@"iPhone2,1"]) ret = NO; else if ([platform isEqualToString:@"iPod1,1"]) ret = NO; else if ([platform isEqualToString:@"iPod2,1"]) ret = NO; else if ([platform isEqualToString:@"iPod3,1"]) ret = NO; return ret; }
//If a newer version exist if ([aux rangeOfString:@"iPhone"].location!=NSNotFound) { int version = [[aux stringByReplacingOccurrencesOfString:@"iPhone" withString:@""] intValue]; if (version == 3) return @"iPhone4" if (version >= 4) return @"iPhone4s";
} if ([aux rangeOfString:@"iPod"].location!=NSNotFound) { int version = [[aux stringByReplacingOccurrencesOfString:@"iPod" withString:@""] intValue]; if (version >=4) return @"iPod4thGen"; } if ([aux rangeOfString:@"iPad"].location!=NSNotFound) { int version = [[aux stringByReplacingOccurrencesOfString:@"iPad" withString:@""] intValue]; if (version ==1) return @"iPad3G"; if (version >=2) return @"iPad2"; } //If none was found, send the original string return sDeviceModel; }
Based on the very good answers above, here is what I came up with. This is very similar to @Rodrigo's answer, but addresses @Oliver's concern from the comment on that answer. This also provides the option of including the model string in the output string.
You can use the UIDevice class as so:
ReplyDeleteNSString *deviceType = [UIDevice currentDevice].model;
if([deviceType isEqualToString:@"iPhone"])
// it's an iPhone

This is an updated for UIDeviceHardware.m from the answer above
ReplyDelete- (NSString *) platformString{
NSString *platform = [self platform];

More usable
ReplyDelete#include <sys/types.h>

@interface UIDevice(Hardware)

@implementation UIDevice(Hardware)

char *machine;
mib[0] = CTL_HW;
mib[1] = HW_MACHINE;
sysctl(mib, 2, NULL, &len, NULL, 0);

sysctl(mib, 2, machine, &len, NULL, 0);
NSString *platform = [NSString stringWithCString:machine encoding:NSASCIIStringEncoding];
free(machine);
return platform;

- (BOOL)hasRetinaDisplay {
NSString *platform = [self platform];
BOOL ret = YES;
if ([platform isEqualToString:@"iPhone1,1"]) {
ret = NO;
}
else
if ([platform isEqualToString:@"iPhone1,2"]) ret = NO;
else
if ([platform isEqualToString:@"iPhone2,1"]) ret = NO;
else

you can reading properties with
NSLog(@"platform %@, retita %@, multitasking %@", [[UIDevice currentDevice] platform], [[UIDevice currentDevice] hasRetinaDisplay] ? @"YES" : @"NO" , [[UIDevice currentDevice] hasMultitasking] ? @"YES" : @"NO");
Just adding the iPhone 4S device code to this thread...
ReplyDeleteThe iPhone 4S will return the string @"iPhone4,1".
Here's a minor update with new models:
ReplyDelete- (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:@"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:@"i386"]) return @"iPhone Simulator";
return platform;
}
Dutchie432 and Brian Robbins have provided great solutions. But there's still one model missing, the Verizon iPhone 4. Here's the missing line.
ReplyDeleteif ([platform isEqualToString:@"iPhone3,2"]) return @"iPhone 4"; //Verizon
What about iPad (1) - isn't there more than one model? I.e. iPad1,1 (Wifi), iPad1,2 (GSM)...
ReplyDeleteCheck for GPS or the camera.
ReplyDeleteHow about this code, if new version was released, you will identifier with the last know device
