Where can I get better Apple documentation?

Question

More often than I'd have hoped I seem to come across method/property definitions in Apple's documentation that are vague at best and meaningless, to me, at worst. For example, take the following method description from NSNumberFormatter Class Reference:

---

setPartialStringValidationEnabled:

Sets whether partial string validation is enabled for the receiver.

- (void)setPartialStringValidationEnabled:(BOOL)b

Parameters

b YES if partial string validation is enabled, otherwise NO.

---

So, let's just assume that the shoddy educational system I went through and any previous projects I've worked on didn't cover "partial string validation" in Cocoa and I would like to dig into it some more to see what this property is all about. Where does one look (aside from Google)? I hate to pester forums for something I should be able to look up easily myself.

I have come across situations like this enough times now that I think I may be approaching Apple's docs incorrectly. Any suggestions? Tips/tricks? 3rd party resources?

Answer 1

Partial string validation is explained in NSFormatter class.
