Stop using constant NSStrings to represent your keypaths: use compiler symbols instead.

Intro

Super simple extension to Justin Spahr-Summers’ object key path validation macro that adds a macro for validating key paths without requiring an instance of the class.

Particularly useful for removing constant NSStrings from your API mappings.

Usage

• JCValidateKeyPath(anObject, aKeyPath)

  • The original macro. Validates the specified key path as a compiler symbol and returns an equivalent NSString representation.
• JCValidateKeyPathWithClass(aClass, aKeyPath)
  • As an extension of the above, does not require an object instance, and can use a Class directly.

Examples:

// With a local instance
NSString *stringInstance = nil;
JCValidateKeyPath(stringInstance, length);

// Without a local instance
JCValidateKeyPathWithClass(NSString, length)

Note that as of v1.0.1 you cannot use JCValidateKeyPathWithClass([NSString class], length). Instead you must use the class symbol directly.

Version history

v1.1.0

Cache now removed and functionality entirely implemented with macros. Many thanks to Stepan Hruda for this.

v1.0.2

General spring-clean and Travis configuration.

v1.0.1

Now casting the object returned from the cache. Without this, class validation wasn’t actually correctly working; you could use any valid selector from any class.

v1.0.0

Initial release.

Have fun!
