Question

Is there a way to store a selector in an NSDictionary, without storing it as an NSString?

Answer 1

SEL is just a pointer, which you could store in an NSValue:

NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys: 
                       [NSValue valueWithPointer:@selector(foo)], @"foo",
                       nil];

To get the selector back, you can use:

SEL aSel = [[dict objectForKey:@"foo"] pointerValue];
