Learn NeXTSTEP (NS) foundation classes - the building blocks of your iOS apps.

When programming iOS apps it's important to get a grounding in at least a few of the most commonly used Objective-C NeXTSTEP (NS) foundation classes.

In this course, you get to take a look at the main classes for working with strings and arrays as well for formatting numbers and dates. You even get a look at the NSDictionary and NSMutableDictionary classes which allow you to both create AND return dictionaries of keys and values.

By the end of this course, you also get a chance to look at enumerating across collections with NSEnumerator as well as serializing NSCoding compliant classes using the NSKeyedArchiver class as well as serializing plists (property lists) using the NSPropertyListSerialization class.
