035 autolayout fun poster@2x
In this episode I dive into the complex world of auto layout. Autolayout is an important and powerful new layout system in iOS 6, but it definitely takes some practice to understand fully. Even after practicing this episode a few times I ran into a couple of snags, however I hope this intro to Autolayout provides useful.

034 upgrading to ios6 poster@2x
Now that iOS 6 is out, and the iPhone 5 is only a day away, it is important to update our applications to make sure there are no issues. In this episode, I convert a rudimentary application to support the taller screen of the iPhone 5 and support iOS 6.

033 core graphics polygons poster@2x
We continue our journey into Core Graphics. This week, we'll draw a polygon with a dynamic number of sides, learn how to use CGMutablePathRef, shadows, clipping paths, and a bit of math.
#32
032 core graphics gradients poster@2x
Core Graphics is a complex topic, but can be very handy to create designs without using images, as well as maintaining resolution independence. In this episode I show how to create a couple of simple gradients using Core Graphics.
#31
031 forms poster@2x
In this episode, I take an existing app and add the ability to post information to a server, including photo uploads. We report on the progress of the upload and configure AFNetworking to do a proper muliti-part HTTP form post. In addition, I cover how to build a standalone static TableViewController to represent a form using Storyboards.
#30
030 parse poster@2x
In this episode I build an app with Parse, a service that provides custom data storage, files, push notifications, a geolocation support.
#29
029 rubymotion poster@2x
RubyMotion is a toolkit that allows you to write native iOS applications using Ruby. Normally I'm pretty skeptical of these alternative frameworks, but RubyMotion is actually quite interesting. In this episode I build a small application and talk about the pros & cons of using the toolkit.

028 creating a cocoapod poster@2x
In this episode, we'll create a CocoaPod out of the modal picker view component we created in episodes 25 & 26. We'll see how to tag & push our code to a github repository and create a podspec so that others can use this component in their projects.

#27
New syntax poster@2x
The latest version of the LLVM compiler supports some excellent new syntax additions to the Objective-C language. In this episode, I cover what the new syntax is, how to use it, and a few caveats to look out for.
#26
Custom picker part 2 poster@2x
In this episode, I continue where I left of in episode 25. I add a nice animation to present & dismiss the picker, as well as a backdrop view that allows you to tap anywhere to cancel.
#25
Custom picker part 1 poster@2x
In this episode, we'll talk about how to extract code from a view controller into a reusable component. We'll create a simple class that combines a UIPickerView with a toolbar for making quick selections from a small list of values. This ran a little long, so it is broken down into 2 parts.
#24
Pull to refresh poster@2x
In this episode, I cover how to implement Pull to Refresh on UITableView using an easy open source project called SSPullToRefresh, by Sam Soffes. I cover the basics, as well as creating a custom loading panel, drawn with Core Graphics.
#23
Storyboards poster@2x
In this episode I dive into Storyboards to lay out view controllers and transitions. I start out by converting a blank slate project to use storyboards, then move on to transitions, dynamic table view prototype cells, and cover static table views at the end. It's a slightly longer video than normal, but if you haven't gotten into storyboards yet, this one's for you.
#22
Custom tabbar poster@2x
In this episode, I continue deconstructing Foursquare's custom UI. This time I focus on how to customize the UITabBar with the iOS 5 customization APIs.
#21
Custom navbar poster@2x
In this episode, I decompose the Foursquare UI and recreate the custom navigation bar, using the iOS 5 customization APIs. You'll see how to set a custom background image, a title view that you can tap on, a custom bar button item, and a custom back button style.
#20
Dissecting apps poster
It can be helpful to draw inspiration from how existing applications are built. In this screencast, we'll look at how to extract & view images from iOS applications you've downloaded from the App Store. In addition, we'll use a proxy to intercept and inspect network traffic so you can see how application APIs behave.
#19
Push notifications poster
In this episode, I set up a push notification server using Rails and Urban Airship, and show the steps required to handle push notifications in an application.
#18
Adhoc provisioning poster
To distribute your application to a wider audience of beta testers, you'll use what is called "adhoc provisioning." In this episode, I create an adhoc build configuration, show how to create a distribution profile for adhoc builds, and how to manually put the build on a device using the iPhone Configuration Utility. Lastly, I cover how to use Test Flight to easily send out builds to be installed over the air.
#17
App provisioning poster
In this episode, I'll walk you through how to set up your Apple development certificate and provisioning profile in order to deploy an application to your device.
#16
Kvo poster
Key Value Observing (or KVO) is a powerful technique that you can use to be notified when a property changes. In this episode, we'll observe a property on a view to respond when it is updated. In addition, we'll look at the ramifications of KVO on your own classes.

#15
Http caching poster
HTTP Caching is an important concept to understand when building iPhone apps that consume HTTP APIs. In this episode, we'll see how leveraging Etags, Last Modified dates, and Cache-Control headers can help make your app more efficient and tolerable to use.
#14
Tracking download progress poster
In this episode, we'll use AFNetworking to track the progress of a file download and display it in a UIProgressView. Once we've downloaded a small movie, we'll play it using MPMoviePlayerViewController.
Shape
#13
Setting up jenkins poster
In this episode, we'll set up a free continuous integration server called Jenkins (previously Hudson) to run our build. We'll configure it to automatically check out changes from git, run the build, and finally run all of our tests. We'll then use a conversion script to translate the test output into JUnit test report files that Jenkins natively understands.

#12
Core data importing poster
In this screencast I'll pull down data from an API, map the JSON to a Core Data Managed Object and import them in bulk on a background thread. Then we'll display the imported content in a UITableView using NSFetchedResultsController.
