I tried it but in .pch file I could not able to work it

#define isIPhone (![[UIDevice currentDevice] respondsToSelector:@selector(userInterfaceIdiom)] || [[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)

#ifdef isIPhone
#define xis @”isIphone”
//This will only be compiled if SOME_CONDITION is defined as a compiler flag

#else
#define xis @”isIpad”
The above code also not working

I’ve beens elf-teaching for about 11 months now and can honestly say that for that the topics I already understand/am familiar with I wish I had seen this info sooner. Also, I like the breadth of topics; fr ex, your info on the preprocessor and conditional compilation is welcome.
