I defined two macros in my _prefix.pch file to make it even easier (and more readable) throughout my code, so you can do:

if (iPad)

or

if (iPhone)

Here's the code:

#ifndef iPad
    #define iPad    (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
#endif
#ifndef iPhone
    #define iPhone  (UI_USER_INTERFACE_IDIOM() != UIUserInterfaceIdiomPad)
#endif

  • is this works for conditional compilation ??? i can use this code to #include "SomeIphoneConditionals.h" or #include "SomeIphoneConditionals.h" ??? – Mouhamad Lamaa Sep 15 '11 at 07:25
  • If you want to have them available in all of your files, put those lines in your _prefix.pch file :) – Javier Soto Sep 15 '11 at 08:46
  • no, i want to include some headers file in a specific classes, also i need to create some methods to be conditionally (example: i want to create a methods to be compiled on ipad and not on iphone) is this possible ? – Mouhamad Lamaa Sep 15 '11 at 08:59

    No, that is not possible. Wether an app is running on an iPhone or on an iPad is determined in runtime. The code is the same (that's what universal app means), so you can't use conditional compilation for that. – Javier Soto Sep 15 '11 at 09:29

It's not conditional compilation, but:

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
    // iPhone Code
} else {
    // iPad Code
}

Which is just a macro for UIDevice's -userInterfaceIdiom method.

Use UI_USER_INTERFACE_IDIOM()

It returns UIUserInterfaceIdiomPhone or UIUserInterfaceIdiomPad
