How to #define the device height as Macro in ios

Question

I want to define SCREEN_HEIGHT in my app. I used the following code, but it always return 568 for me.Can anyone help me for this?

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

#ifdef IS_IPHONE_5
#define SCREEN_HEIGHT 568
#else
#define SCREEN_HEIGHT 480
#endif

Thanks.

see my edited answer. it is working in my code also my friend... — NiravPatel, Sep 27 '13 at 06:56
@PanktiPatel Obviously the `#DEFINE` is a compile-time exercise, but the screen height is a run-time determination. So your `#DEFINE` of `SCREEN_HEIGHT` cannot use a constant, but rather must represent some run-time expression (such as something that looks at `[UIScreen mainScreen]` properties). — Rob, Sep 27 '13 at 07:00

Thanks for the reply. But i don't want to use any variable for this. I just need to define it as in #if and #endif statement. – Pankti Patel Sep 27 '13 at 06:45
@PanktiPatel - without apply condition how can use properly `if` statement ?? – iPatel Sep 27 '13 at 06:53

Try to put #undef SCREEN_HEIGHT before #define SCREEN_HEIGHT

#undef SCREEN_HEIGHT
#ifdef IS_IPHONE_5
#define SCREEN_HEIGHT 568
#else
#define SCREEN_HEIGHT 480
#endif

You Can Also Define Screen Height as:

#define ScreenBound       ([[UIScreen mainScreen] bounds])
#define ScreenHeight      (ScreenBound.size.height)
