Getting the device information using UIDevice

The UIDevice class provides all the information of the device on which your app is running.

UIDevice *deviceInfo = [UIDevice currentDevice]; 

NSLog(@“OS running on device: %@”, deviceInfo.systemName);

   // OS running on device: iPhone OS

NSLog(@“OS Version running on device:  %@”, deviceInfo.systemVersion);

  //OS Version running on device:  7.1

NSLog(@“Device model:  %@”, deviceInfo.model);   

  // Device model:  iPod touch

size_t size;

sysctlbyname("hw.machine", NULL, &size, NULL, 0);

char *machine = malloc(size);

sysctlbyname("hw.machine", machine, &size, NULL, 0);

NSString *deviceModelVersion = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];

free(machine);

NSLog(@"Device model version: %@", deviceModelVersion);

//Device model version: iPhone4, 1

NSLog(@“Device name:  %@”, deviceInfo.name); 

  //Device name:  my iPod
