ios - KVO keyPath for "self"

Question

I'm trying to create a sortDescriptor for an NSArray of NSStrings.

I'm just not sure what to put for the key parameter as I want to use "self" or something equivalent as I just want to use the standard NSString compare.

In this code...

[NSSortDescriptor sortDescriptorWithKey:@"..." ascending:YES];

What should I put where the ... is? self?

Answer 1

self应该管用。您也可以使用description，在这种情况下，排序不仅适用于 NSString，也适用于 NSNumber。
