Question

This is kind of newbie question on objective-c:
I would like to create a static class available throughout my entire code to be accessed by any object. This class will act as a container of several objects.
Can anybody provide a short example of code as how to declare static global variables and methods ?

Answer 1

For my Globals class I have something like this

The .h file looks like this

@interface Globals : NSObject
{

}
+ (Globals *)instance;

@end

and the .m file is like this

import "Globals.h"

@implementation Globals

- (id)init
{
    self = [super init];
    
    if (self) 
    {

    }
    
    return self;
}

+ (Globals *)instance
{
    static Globals *instance = nil;
    
    @synchronized(self) 
    {
        if (instance == nil) 
        {
            instance = [[Globals alloc] init];
        }
    }
    
    return instance;
}

- (void)dealloc
{
    [super dealloc];
}

@end

of course this is a very basic example of a Globals class
