  [[UIDevice currentDevice] model];
  [[UIDevice currentDevice] systemVersion];
  [[UIDevice currentDevice] systemName];
  

  should get you the info you need.

  it's in the iPhone developers guide somewhere... you'll get "iPhone" or "iPod Touch"

  The API said I would get an NSString. It contains a value *like* "iPhone" or "iPod touch"
  I need to know which generation the iPod touch is, though

  Why does that matter? Neither generation of iPod Touch can take a photo.

  For some reason I had been thinking the new iPod Touch could! My bad!
  What's weird though is my app was first rejected because it had a camera function and I made it available to all devices. I resubmitted it as iPhone/iPodTouch2G and it was approved...

  I've found that the app review process is inconsistent at best...
  
  Chalk another one up for the WTF? pile.

  Alternately, instead of testing for specific device models, you could simply test to see if the camera function is available using

  if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
  {
  ...
  }
  

  and enable / disable that portion of your UI accordingly. That way you don't have to worry if they release new iPods with different model names or something like that...

  Hi,
  
  I wanted to use: NSString *device = [[UIDevice currentDevice] model]; for detection on which device is the app installed, but if I try that on iPhone app crash (EXC_BAD_ACCESS), but if I try that on iPod Touch its works OK.
  Know anybody where is the problem?
  
  or find another way to get if the device has microphone or not. I`m using this part of code now:
  

  	NSString *device = [[UIDevice currentDevice] model];
  	
  	if([device isEqualToString:@"iPhone"])
  	{
  		//Has microphone
  		[device release];
  		return true;
  	}
  	
  	else if([device isEqualToString:@"iPhone 3G"])
  	{
  		//Has microphone
  		[device release];
  		return true;
  	}
  	
  	else if([device isEqualToString:@"iPhone 3G S"])
  	{
  		//Has microphone
  		[device release];
  		return true;
  	}
  	
  	if([device isEqualToString:@"iPod touch"])
  	{
  		//Doesn't have microphone
  		[device release];		
  		return false;
  	}
  	
  	if([device isEqualToString:@"iPod touch 2G"])
  	{
  		//Doesn't have microphone
  		[device release];
  		return false;
  	}
  	
  	[device release];
  	return false;

  There are probably something wrong with [device release]. If I deleted this lines with [device release] than its works OK. Can somebody explain to me how its works with the returned NSString object?

  You are not allocating the NSString 'device', so you are not responsible for releasing it.

  This is some code I use to determine the specific make/model of the device.
  
  
  UIDeviceHardware.h

  #import <Foundation/Foundation.h>
  
  @interface UIDeviceHardware : NSObject 
  
  - (NSString *) platform;
  - (NSString *) platformString;
  
  @end
  

  
  UIDeviceHardware.m

  #import "UIDeviceHardware.h"
  #include <sys/types.h>
  #include <sys/sysctl.h>
  
  @implementation UIDeviceHardware
  
  - (NSString *) platform{
  	size_t size;
  	sysctlbyname("hw.machine", NULL, &size, NULL, 0);
  	char *machine = malloc(size);
  	sysctlbyname("hw.machine", machine, &size, NULL, 0);
  	NSString *platform = [NSString stringWithCString:machine];
  	free(machine);
  	return platform;
  }
  
  - (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:@"iPod1,1"])   return @"iPod Touch 1G";
  	if ([platform isEqualToString:@"iPod2,1"])   return @"iPod Touch 2G";
  	if ([platform isEqualToString:@"i386"])   return @"iPhone Simulator";
  	return platform;
  }
  
  @end
  

  
  
  Implementation Code

  	UIDeviceHardware *h=[[UIDeviceHardware alloc] init];
  	NSString *s=[h platformString];

  If possible you should really check for features and not for models. This keeps your application working when new products are released, and is a much more solid concept than tracking models and revisions.

  Clearly, that's the better solution for most tasks, but the original question asks how to determine the device. I use this code myself. When a user logs in to my app, I simply make a note in a database as to which type of device they are using (more so for marketing purposes). Recording each feature's availability is over-kill (and sort of pointless) for what we want to do.
