The repository contains two Objective-C classes designed to split a string into a sequence of short messages close to the international standard of SMS messaging. The GDSMSSplitter class is responsible for actuall splitting. GDSMSCounterLabel is a UILabel subclass which implements the basic pattern for showing a user the number of SMS-messages potentially sent to recipient and the count of leftover symbols. You can check GDSMSSplitterDemo project to see how it's used (it's really straightforward). GDSMSSplitter provides support for GSM 03.38 standard (including basic character set extension table, but excluding national language shift tables). It also supports UTF-16 (UCS-2) encoding standard. Also available via CocoaPods.
