How does one get UI_USER_INTERFACE_IDIOM() to work with iPhone OS SDK < 3.2

Question

Apple advises using the following code to detect whether running on an iPad or iPhone/iPod Touch:

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {         


        

Answer 1

Declare using this

#ifdef UI_USER_INTERFACE_IDIOM
#define IS_IPAD (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
#else
#define IS_IPAD false
#endif

then use check as below

#define DetailLabel_PosX (IS_IPAD ? 200 : 160)

There are also some define for checking iphone 5

#define IS_IPHONE5 (([[UIScreen mainScreen] bounds].size.height-568)?NO:YES)
#define IOS_OLDER_THAN_6 ([[[UIDevice currentDevice] systemVersion] floatValue] < 6.0 )
#define IOS_NEWER_OR_EQUAL_TO_6 ([[[UIDevice currentDevice] systemVersion] floatValue] >= 6.0 )
