It's become common practice to use an @selector for associated objects. This is useful because not only are SELs guaranteed to have a unique address, but because as of Xcode 5, Xcode will warn you when you use a selector that it does not know about. Meaning that it is somewhat protected against spelling mistakes.

This can also be useful when using string keys. For things like state restoration, where you want a key for a given property, you can use the selector for the getter, and get a string from that. Xcode will autocomplete the name for you, and will warn you if you misspell it.

- (void)encodeRestorableStateWithCoder:(NSCoder *)coder
{
    [super encodeRestorableStateWithCoder:coder];
    
    [coder encodeObject:self.feedID forKey:TNKPropertyKey(feedID)];
