Changing code depending on device

I would like the user to be able to click a button and if the device is an iPhone 5 a label will display "This is an iPhone 5" but if the device is an iPhone 4/4s the label will say that instead. Thanks

You can define the following macros at the very top of your view controller (after your import statements).

#define IS_IPHONE (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
#define IS_IPHONE_5 (IS_IPHONE && [[UIScreen mainScreen] bounds].size.height == 568.0f)

And then somewhere in your code do the following:

NSString *text;

if ( IS_IPHONE_5 ) 
    text = @"This is an iPhone 5";
    text = @"This is an iPhone 4/4S";
