how to write condition in prefix.pch

Question

From prefix.pch I want to return 4 if iPhone is iPhone 4 or lower and 5 if iPhone is iPhone 5 or more...

I know how to know the height

#define iPhoneHeight [[UIScreen mainScreen] bounds].size.height

Based on this, I get height, but I want to return 4 or 5.

Any idea how to get this done?

Please avoid to create a completely new tag like [prefix.pch], unless it is really necessary. I have replaced it by the exising tag [precompiled-headers]. — Martin R, Nov 04 '13 at 08:52
It's a terrible idea to put this as a macro in a precompiled header. — CouchDeveloper, Nov 04 '13 at 09:36
Not a macro at all. Perhaps, a category of `UIDevice` if the existing methods in `UIDevice` are not appropriate or not precise enough. — CouchDeveloper, Nov 04 '13 at 14:55

Wouldn't this help ?

    #define isIPhone4or5 CGSizeEqualToSize([[UIScreen mainScreen] preferredMode].size,CGSizeMake(640, 1136)) ? 5 : 4

no.. I need in reply as 4 or 5 as I am setting images programmatically... so I will have is `mainBackground.image = [UIImage imageNamed:[NSString stringWithFormat:@"bg_Categories_iPhone%d.png", iPhone4Or5]];` – Fahim Parkar Nov 04 '13 at 08:29
Then its easy it will be like this #define isIPhone4or5 CGSizeEqualToSize([[UIScreen mainScreen] preferredMode].size,CGSizeMake(640, 1136)) ? 5 : 4 – Chamira Fernando Nov 04 '13 at 09:07

You can compare height with value in points for 4 inch display like this:

#define iPhone4Or5 [[UIScreen mainScreen] bounds].size.height == 568 ? 5 : 4
