Rana Sobhany of Medialets has graciously made this blog post available to our listeners. It comes on the heels of a recent article in Wired. This post discusses some of the ways of protecting your apps. Also, please listen to our interview with Eric Litman, CEO of Medialets, on Unbound Developers to learn about the Medialytics API.

Ever thought that it’s easy to implement an app like Preview? It is simpler than you think.

Note: this article provides a preview of an upcoming Pro topic. The full version of this article with the source code for the example is available to CocoaCast Pro subscribers

Introduction

We're all aware of high profile applications like Adobe CS4 or Final Cut Studio that offer Plug-Ins, we would think that implementing this kind of architecture is out of reach for small Cocoa applications but in fact this is quite simple. Let's see how you can add Plug-Ins to your app.

Introduction

In the last serialization article, I showed you how to use the archiving capabilities of Cocoa. Cocoa is very powerful, so here goes yet another way to serialize objects: Property Lists. Property lists do not give you a way to specify how and what data is to be serialized. You are forced to use plist-serializable data types: NSArray, NSDictionary, NSData, NSDate, NSNumber, and NSString, their mutable twins, or their Core Foundation equivalents. So, it’s impossible to serialize an arbitrary object like you would with archives, but it is very convenient to store configuration properties, that are usually stored in dictionaries, etc.

In Episode 44 of the Cocoacast show, we’ve talked about how XML can be used to develop applications. I’ve covered basics of NSXML and NSXMLParser. Examples, that you can find in our Code Library cover various ways of parsing and searching XML data. This is an advanced episode, and as such, we will discuss things that go beyond use in a typical application. Today, we will discuss XML manipulation: how to build and modify DOM model and how to apply XSLT transformations.
