Global NSString

Question

I need to create an NSString, so I can set its value in one class and get it in another. How can I do it?

Accepted Answer

if you write:

```
NSString *globalString = @"someString";   
```

anywhere outside a method, class definition, function, etc... it will be able to be referenced anywhere. (it is global!)

The file that accesses it will declare it as external

```
extern NSString *globalString;
```

This declaration signifies that it is being accessed from another file.
