And you've listed about 90% of the things I usual end up subclassing because I've hit some limitation.
Also I wasn't talking specifically about UIKit. Foundation is another great framework that I've subclassed many times.
It's not perfect but Apple puts a lot of work into documenting how to subclass their frameworks. Third-party UI frameworks like this are much less forgiving.
- Zev 14y agoCan you give an example of some things that you subclass?
- reidmain 14y agoFrom Foundation? NSDictionary, NSArray and NSOperation instantly jump to mind.
- Zev 14y agoWhat do you get out of subclassing NSDictionary or NSArray that you don't get out of a category?
- reidmain 14y agoWell in this case I subclassed them so I could have the backing data source only weakly reference the items in the dictionary/array and because I subclassed them I can use them wherever NSDictionary or NSArray is an accepted parameter.
