How to programmatically differentiate between iphone 4 and iphone 4S?

Question

I am working on app which needs to check the iphone model, but I\'m not able to find any solution. I will be thank full for any suggestion.

Answer 1

For my purposes I've written a tiny library that abstracts away the underlying C calls and presents an Objective-C interface.

NSLog(@"Big model number: %d", deviceDetails.bigModel);
//Big model number: 4

NSLog(@"Small model number: %d", deviceDetails.smallModel);
//Small model number: 1

if (deviceDetails.model == GBDeviceModeliPhone4S) {
    NSLog(@"It's a 4S");
}
//It's a 4S

if (deviceDetails.family != GBDeviceFamilyiPad) {
    NSLog(@"It's not an iPad");
}
//It's not an iPad

NSLog(@"systemInfo string: %@", [GBDeviceInfo rawSystemInfoString]);
//systemInfo string: iPhone4,1

It's on github: GBDeviceInfo

Answer 2

Try using following : you will get all the detail informations of the Device...

NSLog(@"uniqueIdentifier: %@", [[UIDevice currentDevice] uniqueIdentifier]);
NSLog(@"name: %@", [[UIDevice currentDevice] name]);
NSLog(@"systemName: %@", [[UIDevice currentDevice] systemName]);
NSLog(@"systemVersion: %@", [[UIDevice currentDevice] systemVersion]);
NSLog(@"model: %@", [[UIDevice currentDevice] model]);
NSLog(@"localizedModel: %@", [[UIDevice currentDevice] localizedModel]);

If above does not work for you then use github project

EDIT :

Whether you are on an iPhone or a iPod Touch:

UIDevice *device = [UIDevice currentDevice];
NSString *systemName = [device systemName];

To detect the version of the OS:

UIDevice *device = [UIDevice currentDevice];
NSString *systemVersion = [device systemVersion];

For Reference: how do I detect whether I have iPhone 2G,3G,3GS

Answer 3

This is much simpler one. SIMPLE ENOUGH FOR JUST COPY & PASTE

Also, I've included matching model name for machine name.

//MARK: Required import
#import <sys/utsname.h>

+ (NSString*)deviceModelName {

    struct utsname systemInfo;
    uname(&systemInfo);

    NSString *machineName = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];

    //MARK: More official list is at
    //http://theiphonewiki.com/wiki/Models
    //MARK: You may just return machineName. Following is for convenience

    NSDictionary *commonNamesDictionary =
    @{
      @"i386":     @"iPhone Simulator",
   @"x86_64":   @"iPad Simulator",

   @"iPhone1,1":    @"iPhone",

   @"iPod5,1":  @"iPod 5th Gen",
   @"iPod7,1":  @"iPod 6th Gen",
    };

    NSString *deviceName = commonNamesDictionary[machineName];

    if (deviceName == nil) {
        deviceName = machineName;
    }

    return deviceName;
}

Answer 4

Here is a common method of retriving the device model. There are no NS methods for this, so you gotta use c

#include <sys/types.h>
#include <sys/sysctl.h>

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

Update a list of devices: 
In future will be updated with iPad 4.
+  (NSString*)deviceModelName {
/*
 @"i386"      on the simulator
 @"x86_64"    on the simulator
 @"iPod1,1"   on iPod Touch

 @"iPod4,1"   on iPod Touch Fourth Generation
 @"iPod5,1"   on iPod Touch Fourth Generation
 @"iPhone1,1" on iPhone
 @"iPhone1,2" on iPhone 3G
 @"iPhone2,1" on iPhone 3GS
 @"iPad1,1"   on iPad
 @"iPad2,1"   on iPad 2
 @"iPad2,5"   on iPad mini 1
 @"iPad3,1"   on iPad 3
 @"iPhone3,1" on iPhone 4
 @"iPhone4,1" on iPhone 4S
 @"iPhone5,1" on iPhone 5
 */

struct utsname systemInfo;

uname(&systemInfo);

NSString *modelName = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];

if([modelName isEqualToString:@"i386"] || [modelName isEqualToString:@"x86_64"]) {
    modelName = @"iPhone Simulator";
}
else if([modelName isEqualToString:@"iPhone1,1"]) {
    modelName = @"iPhone";

return modelName;

Answer 6

However if you are running application on simulator, you will never get device name as "iPhone 6" of "iPhone6+" or anything like that. I am currently using Xcode Version 6.2 (6C131e) in which I have successfully checked device type even on simulator using few macros. Those are

// ******************* DEVICE INDENTIFICATION MACROS *****************//
#define IS_IPAD             (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
#define IS_IPHONE           (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
#define IS_IPHONE4          (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 480.0f)
#define IS_IPHONE5          (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 568.0f)
#define IS_IPHONE6          (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 667.0)
#define IS_IPHONE6PLUS      (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 736.0)
#define IS_RETINA           ([[UIScreen mainScreen] respondsToSelector:@selector(displayLinkWithTarget:selector:)] && ([UIScreen mainScreen].scale == 2.0))
