BTNSDateFormatterFactory

Smart reuse of NSDateFormatter instances.

NSDateFormatter class is very useful to display dates the way you want, handling regional settings, locales and formats.

The bad thing about NSDateFormatter is the cost to create a new instance or set format and locale. Actually these actions are one of the most slow operations on iOS SDK and you really must avoid it.

DFDateFormatterFactory is here to help you with this. This class retain the last 15 date formatter instances and return the already loaded based on format and locale you want. Also, the cache were implemented using the standard NSCache and should handle memory fine when memory warnings happens.
