Hi all. I've got a dictionary of objects that contain properties and need to check if one object has a certain value.
I was thinking I could use collection operators and build an array where the value of an an object's property matches that I'm looking for.
Then if the array contains that value, we have a match.
If each objects in the array has a bunch of properties and one of those properties is called "thing", how would I build an array where the contents of thing would equal a certain value?
I'm sure I could walk the array, but I expect there is a more efficient method already built in to Cocoa for this.
Thanks in advance.
