I have an array. Each array entry is a dictionary. Each dictionary has two key/value pairs (all are strings).

Now I get from somewhere else the value (a string) corresponding to one of the keys. It's exactly the same string, content-wise (not address-wise). What I need: a reference/pointer to THAT dictionary inside the array which contains this string as the value of the key (I know what key it is).

How would I do that?

You may be able to accomplish what you're looking for using -[NSArray filteredArrayUsingPredicate:].

You won't get the index of the dictionary which matches, but you will get a reference to it (or them, if more than one match).

Cheers,
