NSString (Emoji) extends the NSString class to provide custom functionality related to the Emoji emoticons.
Through this category, it is possible to turn cheat codes from Emoji Cheat Sheet into unicode emoji characters and vice versa (useful if you need to POST a message typed by the user to a remote service).
There are just two methods, which should be very self explanatory:
/**
Returns a NSString in which any occurrences that match the cheat codes
from Emoji Cheat Sheet <http://www.emoji-cheat-sheet.com> are replaced by the
corresponding unicode characters.
Example:
"This is a smiley face :smiley:"
Will be replaced with:
"This is a smiley face \U0001F604"
*/
- (NSString *)stringByReplacingEmojiCheatCodesWithUnicode;
/**
