Detect iOS device type

Question

In my application (written in Objective-C), how do I detect if the device is an iPhone, iPad, or iPhone5?

if([[UIDevice currentDevice]userInterfaceIdiom] ==

Here are a bunch of constants you can stick in your PCH file and use throughout your application which give you a lot of different things you can test for. (Widescreen here means iPhone 5 "taller" screen)

#ifndef IS_WIDESCREEN
#define IS_WIDESCREEN   (fabs((double)[[UIScreen mainScreen] bounds].size.height - (double)568) < DBL_EPSILON)
#endif

#ifndef IS_IPHONE
#define IS_IPHONE       ([[[UIDevice currentDevice] model] isEqualToString:@"iPhone"])
#endif

#ifndef IS_IPOD
#define IS_IPOD         ([[[UIDevice currentDevice] model] isEqualToString:@"iPod touch"])
#endif

#ifndef IS_IPAD
#define IS_IPAD         ([[[UIDevice currentDevice] model] isEqualToString:@"iPad"])
#endif

#ifndef IS_IPHONE5
#define IS_IPHONE5      (IS_WIDESCREEN && IS_IPHONE)
#endif

#ifndef IS_IPOD5
#define IS_IPOD5        (IS_WIDESCREEN && IS_IPOD)
#endif

You can use it like this:

if(IS_IPHONE5){
    // load iPhone5 code/nibs
}

if(IS_WIDESCREEN){
    // load 4" screen stuff here
}
