fliter through arrays help

[Punkjumper]

I want to take the values from the playerNames array and search for the arrays that match the values of those names and then delete the entires in that array.

I can access the playerNames and scores arrays with valueForKey because I created those arrays and I know the key value but the arrays with the players names are created when the user enters the player name in the app.

I'm assuming that I need to compare the values from the playerNames array with key values from the arrays in my base dictionary. if they are equal then do something but I don't know how to go about this.

can you point me in the right direction?
