Static variable cannot be accessed from another class

Question

I have a static variable that i want to access from another class in the same project in X-Code. I have declared it in the .h file AND the .m file, gave it a value, and then when i accessed the other class, i got an error message saying that: "Property 'xx' is not found on object of type 'yy'" i declared the variable as extern in the .h, and redeclared it as the variable type in the .m. I have tried to change it to static in the .h, but it still doesn't work. And yes, i have imported the file containing the variable, in case that is the problem. Can anyone help me? EDIT: this is the code that i'm currently using: source.h ``` static int anObject; @interface source : NSObject ``` source.m ``` static int a = 2 @implementation source ``` destination.m ``` # include "source.h" @implementation destination - (void) anObjectTestFunction { printf("%d", source.anObject); //the first version printf("%d", anObject); //second version } ``` now after i went to the second version, the variable anOb…

Accepted Answer

I am assuming the static variable declared in the .h file is outside the `@interface`. So something like:

```
static NSString *myObjectTest = @"Test";

@interface MyObject : NSObject 
@end
```

If that is the case then you will not be able to access it using something like:

```
MyObject *obj = [[MyObject alloc] init];
[obj myObject]
```

or

```
obj.myObject
```

That is what is giving you the "Property 'xx' is not found on object of type 'yy'". That static variable is not a property on the object of MyObject.

That static variable is accessible like so `myObjectTest` as long as you import the .h file

Update See Chuck's comment below why this is a bad idea to do this way.
