Even easier, use the Singleton design pattern and implement a
+sharedInstance class method in your class. This is how existing
singletons like NSFileManager work.

Read up on categories. Then make the instance of your Debug class a
static variable in your category implementation file, and use a
method you added to NSApplication via your category to return it.

Hi all,
I've created a "Debug" class in my app, which contains an instance
variable and several methods. I want to add this to my application
but can't see how.
I can add it to MyDocument class like this:
- (id)init
{
self = [super init];
if (self) {
// other stuff
debug = [Debug new];
}
return self;
}
- (void) dealloc
{
// other stuff
[debug release];
[super dealloc];
}
But I want a global instance for the application as a whole. How do
I do this? Do I have to subclass NSApplication just to create a
global variable?
I want to be able to call it from any class in my app, such as:
[[NSApp debug] myMethod];
Please reply to the list.
Thanks,
Tom
