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.

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.

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.
lock
#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.
lock
#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.
Shape
#11
Core data basics poster
Core Data is Apple's framework for persisting data on Mac & iOS. It can be though of as an ORM, however it's probably a lot different than most ORMs you've used in the past. In this episode, we'll set up Core Data from scratch so you can see all the moving parts.

#10
Fun with blocks poster
Blocks are a great way to simplify code when dealing with asynchronous tasks (using GCD), callbacks, and atomic operations. In this episode, we'll look at a few ways you can use blocks in your code.
Shape
#9
Arc poster
In this episode, I'll show you how to convert your project to use Automatic Reference Counting (or ARC) to eliminate the need to use retain, release, autorelease, and dealloc in your Objective-C code!
Shape
#8
008 poster
UITableView can support skimming through many rows of data, however fetching large amounts of remote data can slow down your app, use up too much memory, and bog down your web server. This is all wasteful if users aren't ever going to scroll down that far. In this episode you'll learn how to perform automatic UITableView paging using an easy technique.
Shape
#7
007 poster
It can be useful to save lightweight application data to disk so that it persists between application launches. This episode will show you how to serialize common objects such as NSArray and NSDictionary to disk, as well as implementing custom object serialization using NSKeyedArchiver.
Shape
#6
Poster
AFNetworking is a simple-yet-powerful toolkit for making HTTP requests dead simple. It is my current go-to framework for writing API clients in iOS applications.
Shape
#5
Cocoapods poster
Looking for a solution for managing dependencies similar to RubyGems? Look no further! CocoaPods is a great solution that makes it easy to manage dependencies to 3rd party libraries in your projects.
Shape
#4
Kiwi poster
In this episode, I show you how to start testing with Kiwi, a test framework built on top of SenTestKit that has a style similar to Rspec.

#3
Poster tableview basics
UITableView is one of the most common controls in UIKit. This episode will show you the basics of how to make your view controller act as the delegate & datasource for the table view, as well as reading sample data (beers) from a plist file.
