A lot of hard work has gone into this book already and I see it becoming the definitive text on the subject of Core Data. The release date is slated for March 30, 2009, but it’s great to see it in beta. If you want to pick up the beta in PDF, it is available now from Pragmatic here: Core Data: Apple’s API for Persisting Data under Mac OS X.
While new Cocoa programmers will find it a great help to getting started quickly with Core Data, the book also covers some really interesting and advanced topics such as data versioning and migration, Spotlight/Quick Look integration, Sync Services, and multi-threading. You can really see Marcus’ command of the subject shine in these chapters which are already available in the beta.
Give Marcus some feedback on the book as it progresses. It’s going to be a great reference for any Cocoa Developer looking to harness the power of Core Data.
$21.00 for the beta PDF $41.35 for the beta PDF plus hard copy when it’s released in March.
Mad props to Marcus. Congratulations!
It is often helpful to create a custom control for you application that will display a value as a level like a gas gauge shows how full your tank is. In this post I will demonstrate how to create a three layer tree that will show the current rotation of a circular layer as the value from a slider (NSSlider) is updated in real time. The layers include the root layer, the rotation layer, and a text layer that will display the current rotation in degrees. (more…)
Now that the NDA has been lifted we can all finally come out of the closet :)
If you have not heard, O’Reilly is hosting a conference on November 18, 2008 to discuss all things iPhone. I have been invited to attend the conference as a Panelist.
Please come and join the conference, if nothing else, to heckle me :)
The list of speakers (as opposed to panelists), is quite impressive and definitely worth the trip.
Similar to one of my first blog posts on building a basic application for Mac OS X using xcode 3.0, I am going to explain for beginning iPhone/iPod Touch developers how to build the most basic Cocoa Touch application using Interface Builder and an application delegate in xcode 3.1. This tutorial post is really to provide a quick how-to. I won’t go into any depth explaining why things are done the way they are done, but this should help you get up and running with your first application pretty quickly so that you too can clog the App Store with useless superfluous apps (kidding… just kidding).
If you are a visual learner, it may be helpful to you to instead watch a video presentation of this tutorial. I’ve posted it on the site, but you’ll have to click the link to see my Cocoa Touch Video Tutorial. (more…)
