Question

I set a value in one class and then I want to retrieve that value without creating an object for it.

When I use classname.variableName from another class(which I declare the variableName as property and synthesize it) I get an unknown class method error.

How can I just set an NSString in one class and just reference it from another. I dot want to create an object.

Perhaps you are setting it up incorrectly. Here is how you could set it up:

@interface ClassThatAlreadyExists : NSObject {
    // Other ivars
    NSString *variableName;
}

// Other @property's
@property (nonatomic, copy) NSString *variableName;

@end

@implementation ClassThatAlreadyExists

// other @synthesize's
@synthesize variableName;

// rest of implementation

@end
