Instance Property

keyName

The name of the custom attribute key.

Declaration

@property(readonly) NSString *keyName;

Discussion

The key name is a string that contains only ASCII characters and no punctuation other than the underscore (that is “_”). The prefix kMD is reserved. To create a custom attribute key name, it’s recommended that you use a reverse DNS format that includes your company name and does not include the period character (“.”). For example, a key name of the form com_mycompany_myapp_mykeyname works well.
