How to check the device is iPhone 5? [duplicate]

Question

How can I check if an application running on iPhone 5 or not and then do something?

Answer 1

#define IS_IPHONE_5 ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )568 ) < DBL_EPSILON )

then in the code:

if (IS_IPHONE_5) { 
   //is iphone 5
}

Answer 2

You're likely concerned with the window size, not the make/model, this will do:

CGRect screenRect = [[UIScreen mainScreen] applicationFrame];
if (screenRect.size.height == 568)
{
 // this is an iPhone 5+
}
