iPhone - NSError reference : constants and code

I'm searching some precise doc where I 开发者_开发问答can associate an error number to its constant. Let's say, for example, I'm searching the constant of NSError.code = 102. How may I do to find it ? Searching the Web does not help. Searching the headers file is a headache.

How would you do this ?

you can find some of refrences here for NSError

http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSError_Class/Reference/Reference.html

you can found some of error detail here

The code should belong to the domain of NSError, check the documentation for the associated error domain and you should find the correct code. The domain is also a good hint of which headers to search if documentation is unavailable. Apple does list the Foundation Constants.

It's WebKitErrorDomain - WebKitErrorFrameLoadInterruptedByPolicyChange
