Re: Creating an NSTimer subclass

I want to add a couple of methods to NSTimer, but I can't use a category because I need to add a couple of instance variables as well.

It's far from ideal, but you can kinda-almost add instance variables in a category by storing them in a static NSDictionary, keyed by self.
eg :

static NSDictionary* fakeInstanceVars = nil;

@implementation NSTimer (ExtraStuff)

-(NSString*)magicalValue
{
NSDictionary* instanceVars = [fakeInstanceVars objectForKey: [NSNumber numberWithInt:self]];
return [instanceVars objectForKey:@"magicalValue"]
}

@end


Unpleasant, I know, but it's an option...
