Are your trying to access the "Artist" key of your artDict dictionary? If so, yo can do the following:

NSString *someArtist = [artDict valueForKey:@"Artist"];

This will return the value for the key "Artist".

You can find more information on the NSDictionary class here: (https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSDictionary_Class)
