Additional methods for NS(Mutable)Dictionary to support array subscripting syntax for SDK's before iOS 6.
Xcode 4.4 does support the new modern Objective-C runtime features for NSNumber, NSArray and NSDictionary. All but subscripting (like myArray[42] instead of [myArray objectAtIndex:42] and myDict[@"name"] instead of [myDict valueForKey:@"name"]). This only is available with the iOS 6.0 SDK for Xcode 4.5.
With this category you can enable this for iOS 5.1 and earlier for Xcode 4.4.
See also NSArray+OMRuntime for a category for NSArray.
