ObjectToXPC

A bunch of categories for converting a few types of Objective-C objects (defined in the Foundation framework) to and from XPC objects.

Also see the blog post about it "Convert Between XPC Objects and Objective-C Objects."

Supported objects

Objective-C objects

  • NSArray (where the elements are one of the supported),
  • NSData,
  • NSDate,
  • NSDictionary (where the elements are one of the supported, keys must either be of the NSString class or define the -description method),
  • NSNull (only in collections),
  • NSNumber,
  • NSString.

XPC object types

  • XPC_TYPE_ARRAY
  • XPC_TYPE_BOOL
  • XPC_TYPE_DATA (to and from NSNumber)
  • XPC_TYPE_DATE
  • XPC_TYPE_DICTIONARY
  • XPC_TYPE_DOUBLE (to and from NSNumber)
  • XPC_TYPE_INT64 (to and from NSNumber)
  • XPC_TYPE_UINT64 (to and from NSNumber)
  • XPC_TYPE_NULL
  • XPC_TYPE_STRING

Requirements

The project requires Mac OS X 10.7+ and Xcode 4.2 to build and Mac OS X 10.7+ to run as the XPC Services API was first introduced in OS X 10.7. Will not work on iOS as the XPC API is not available here. Furthermore, the project have been written for automatic reference counting (ARC).

Usage

Either include the source files directly (in which case you will also need the (ObjectToXPC-Private.h header file) or link with the library.
