Is objectAtIndexedSubscript available in IOS5?

Question

The documentation says it\'s available in MacOS 1.08.

So what\'s the story? What about for iOS5?

It\'s a very important selector because self[5] will actuall

Answer 1

While objectAtIndexedSubscript: is not available previous to iOS 6, NSArray and NSDictionarysubscripting is available. That means that you can use syntax like this:

myArray[2] = @"thingie";
myDictionary[@"roger"] = @"barry";

And it will deploy back to iOS 4.

However NSOrderedSet subscripting will not work on iOS 5 and previous. For that, you will need to provide a category that redirects objectAtIndexedSubscript: calls to objectAtIndex:.

Addendum: Apple's docs for NSMutableOrderedSet are also incorrect. It states that index subscripting does an insert, when in reality is does a replace (as one would expect).
