MF - How to copy NSMutableDictionary

"
Remember that you can't put an NSArray into a dictionary. You only put an NSArray*
into a dictionary. When you use [dictionaryWithDictionary:] or [initWithDictionary:],
the new dictionary has copies of all of the values in the original array, including
COPIES OF THE POINTERS. Both pointers still refer to the same array object, so
operating on the array* in one of the dictionaries will will modify the 'array' in both
dictionaries."

Unfortunately they have a really terrible API that's inherently broken in a co-

it better."

ency."

More of the same - Where’s the difference between setObject:forKey:
and setValue:forKey: in NSMutableDictionary?

"Both "value" and "object" are of type id, so can be any object. Key is once
a string, and in the other case an id. One of them seems to retain the object,
and the other don't. What else?"

Walking Smarts - WSCoreLaziness

"WSCoreLaziness is a shot at making ActiveSupport for Cocoa frameworks.
The idea is simple - create a collection of (as of this writing) Foundation
framework categories that aim to shorten the amount of your typing and
increase the amount of hitting Esc and Tab keys, provide familiar API and
sensible defaults."

"We're going to take a look at the new UICollectionView class Apple
introduced in iOS 6. It's used to display a grid of cells, and what better
to display in those cells than some beautiful photos from 500px?"
