how to declare a external integer variable so that i can access that in in view controller

Question

i want to access variable in all views ,so how can i declare it ....

Answer 1

Have a look at Singletons See here and here

Answer 2

If you really want a global variable, then in a header file that is #included by all your view controllers, put this:

extern int MyVariable;

Then in some .m file (exactly one), put this:

int MyVariable = 0;

But check out that answer about Singletons.
