Answer 1

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",    @"iPhone1,2":    @"iPhone 3G",    @"iPhone2,1":    @"iPhone 3GS",    @"iPhone3,1":    @"iPhone 4",    @"iPhone3,2":    @"iPhone 4(Rev A)",    @"iPhone3,3":    @"iPhone 4(CDMA)",    @"iPhone4,1":    @"iPhone 4S",    @"iPhone5,1":    @"iPhone 5(GSM)",    @"iPhone5,2":    @"iPhone 5(GSM+CDMA)",    @"iPhone5,3":    @"iPhone 5c(GSM)",    @"iPhone5,4":    @"iPhone 5c(GSM+CDMA)",    @"iPhone6,1":    @"iPhone 5s(GSM)",    @"iPhone6,2":    @"iPhone 5s(GSM+CDMA)",     @"iPhone7,1":    @"iPhone 6+ (GSM+CDMA)",    @"iPhone7,2":    @"iPhone 6 (GSM+CDMA)",     @"iPhone8,1":    @"iPhone 6S (GSM+CDMA)",    @"iPhone8,2":    @"iPhone 6S+ (GSM+CDMA)",     @"iPad1,1":  @"iPad",    @"iPad2,1":  @"iPad 2(WiFi)",    @"iPad2,2":  @"iPad 2(GSM)",    @"iPad2,3":  @"iPad 2(CDMA)",    @"iPad2,4":  @"iPad 2(WiFi Rev A)",    @"iPad2,5":  @"iPad Mini 1G (WiFi)",    @"iPad2,6":  @"iPad Mini 1G (GSM)",    @"iPad2,7":  @"iPad Mini 1G (GSM+CDMA)",    @"iPad3,1":  @"iPad 3(WiFi)",    @"iPad3,2":  @"iPad 3(GSM+CDMA)",    @"iPad3,3":  @"iPad 3(GSM)",    @"iPad3,4":  @"iPad 4(WiFi)",    @"iPad3,5":  @"iPad 4(GSM)",    @"iPad3,6":  @"iPad 4(GSM+CDMA)",     @"iPad4,1":  @"iPad Air(WiFi)",    @"iPad4,2":  @"iPad Air(GSM)",    @"iPad4,3":  @"iPad Air(GSM+CDMA)",     @"iPad5,3":  @"iPad Air 2 (WiFi)",    @"iPad5,4":  @"iPad Air 2 (GSM+CDMA)",     @"iPad4,4":  @"iPad Mini 2G (WiFi)",    @"iPad4,5":  @"iPad Mini 2G (GSM)",    @"iPad4,6":  @"iPad Mini 2G (GSM+CDMA)",     @"iPad4,7":  @"iPad Mini 3G (WiFi)",    @"iPad4,8":  @"iPad Mini 3G (GSM)",    @"iPad4,9":  @"iPad Mini 3G (GSM+CDMA)",     @"iPod1,1":  @"iPod 1st Gen",    @"iPod2,1":  @"iPod 2nd Gen",    @"iPod3,1":  @"iPod 3rd Gen",    @"iPod4,1":  @"iPod 4th Gen",    @"iPod5,1":  @"iPod 5th Gen",    @"iPod7,1":  @"iPod 6th Gen",     };      NSString *deviceName = commonNamesDictionary[machineName];      if (deviceName == nil) {         deviceName = machineName;     }      return deviceName; }

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; }
