If you truly want a global string, you can simply define it outside of any class definition, function, etc. in your Global class.

In Global.h:

extern NSString *globalString;

In Global.m:

NSString *globalString = @"a string";

To reference it in another class:

#import Global.h
...
NSString *aString = globalString;
...

If you simply want to pass a string from your first view to your second, look into properties.
