Core Data and Threads, Without the Headache | Cocoa Is My Girlfriend
I know I mentioned we would talk about customizing the fetch requests, however, I have been working on some code related to the Active Record Fetching project, which I am renaming to MagicalRecord, that is also just as useful as fetching–threading. Whenever most cocoa developers mention threading and Core Data in the same sentence, the reaction I see most often is that of mysticism and disbelief.
Saving JSON to Core Data | Cocoa Is My Girlfriend
Hi, I’m new here. You may know me as @atomicbird on Twitter. Just a few days ago my book Core Data for iOS: Developing Data-Driven Applications for the iPad, iPhone, and iPod touch (co-written with the excellent Tim Isted) was published, and Matt invited me to contribute some Core Data tips to CIMGF. I’m going to start off discussing taking JSON data from a web service and converting it to Core Da
Cocoa Is My Girlfriend ≫ Blog Archive ≫ NSOperation Example
Forget Mandelbrot sets (Apple coding headstarts) and Expression Trees. NSOperation is really not that hard. In his post, Marcus introduced how to use NSOperation to greatly simplify multi-threading tasks in your application. I am now going to provide a step-by-step walk-through sample application that uses NSOperation, NSOperationQueue, and QTKit. While looking around the Internet, I noticed that
Super Happy Easy Fetching in Core Data | Cocoa Is My Girlfriend
First up, I want to thank Matt Long and Marcus Zarra for allowing me to guest post on CIMGF. This post is the first in a short series of topics describing how to I’ve made using Core Data a little simpler without giving up the power features you still need. The full project from which this series is derived is available on github. Core Data, for both iPhone and Mac, is a very powerful framework fo
Cocoa Is My Girlfriend » My current Prefix.pch file
I have posted and discussed this file a few times but as with all things it has been touched, tweaked, and generally improved upon. In this article we will discuss the latest iteration of my `Prefix.pch` file. As with anything I post, it is available for you to use as you see fit. ## The File For those who don’t want to read the entire post, here is the file: #ifdef DEBUG #define DLog(...) NSLog(@
Cocoa Tutorial: Windows OOP vs Cocoa MVC | Cocoa Is My Girlfriend
Encapsulate everything! Right? Or not. I was watching the Cocoa developers email list today and saw a post asking for help getting two views to communicate between one another. Having been a Windows programmer for longer than I’m willing to admit, I recognized the question as it was one that I also had when I moved to Objective-C on the Mac. I think I can ask the question more succinctly now than
Cocoa Tutorial: NSOperation and NSOperationQueue | Cocoa Is My Girlfriend
Threading is hard in any language. And what is worse, when it goes wrong, it usually goes wrong in a very bad way. Because of this, programmers either avoid threading completely (and refer to it as the spawn of the devil) or spend a LOT of time making sure that everything is perfect. Fortunately, Apple has made a lot of progress in OS X 10.5 Leopard. NSThread itself has received a number of very u
