MessagePack for Objective-C / iPhone

This is a wrapper for the C MessagePack parser, building the bridge to Objective-C. In a similar way to the JSON framework, this parses MessagePack into NSDictionaries, NSArrays, NSNumbers, NSStrings, NSDatas and NSNulls. This contains a small patch to the C library so that it doesn't segfault with a byte alignment error when running on the iPhone in armv7 mode. Please note that the parser has been extensively tested, however the packer has not been. Please get in touch if it has issues.

Parsing Usage

#import "MessagePack.h"
...
NSData* myData = ...
NSDictionary* parsed = [myData messagePackParse]; //decodes raw bytes into NSStrings using UTF8
NSLog(@"%@", [parsed description]);

Handling Raw Data

NSData* myData = ...

//default: try to decode raw bytes into utf8 strings, parse to NSNull on fail
NSDictionary *parsed = [myData messagePackParseWith:MPRawsAsNSString_NSNullOnFail];

//try to decode, parse to NSData of the original bytes on fail
NSDictionary *parsed = [myData messagePackParseWith:MPRawsAsNSString_NSDataOnFail];

//try to decode, raise an exception on fail
NSDictionary *parsed = [myData messagePackParseWith:MPRawsAsNSString_ExceptionOnFail];

//always parse to NSData
NSDictionary *parsed = [myData messagePackParseWith:MPRawsAsNSString_ExceptionOnFail];

Packing Usage

#import "MessagePack.h"
..
NSData* packed = [someArray messagePack];
NSData* packed = [someDictionary messagePack];
NSData* packed = [someData messagePack];
