Have I mentioned lately how awesome NSScreencast is? No? Worth the subscription. Check it out if you’re an iOS developer. Or even if you’re not and you want an example of how to do coding screencasts well.

Foster Bass

Got tired of dead-end googling so I checked to see if @NSScreencast had covered what I was looking for. Of course he had, 4 years ago. Should have checked there first.

Aijaz Ansari

One 13-minute episode of @NSScreencast just paid for the yearly subscription fee in amount of time saved. Do it.

Sam Soffes

Seriously great stuff even for seasoned developers. I’ve learned a good amount from Ben’s videos.

James Dempsey

You can really expand your development horizons in just a few minutes a week with NSScreencast.

Alexis Gallagher

Random PSA for iOS developers: @NSScreencast is a great resource, and worth every penny. It’s high quality, practical, and honest.

Nate Armstrong

Can’t say enough good things about @NSScreencast There is gold in the Road Trip DJ Series.

Karl Oscar Weber

I just reuppped my subscription to @NSScreencast. [An] indespensible resource if you’re into iOS or Mac Development.

Marcus Ziadé

Just finished @NSScreencast series on Modern CollectionViews. Strongly recommended. Programmatic UI, nicely structured code, easily approachable explanation style. 👌

  • Swift Operators

    #127

    One of Swift's powerful features is the ability to define custom operators. In this episode we take a look at two examples of custom operators, one for easy regular expression matching, and another for computing the dot product between two vectors.

  • Swift Classes

    #126

    Continuing on with our Swift exploration, we focus this time on Swift classes. We talk about initializers, inheritance, protocols, type inspection, and more.

  • Swift Basics

    #125

    In this episode we take a first look at Apple's brand new programming language Swift.

  • Method Swizzling

    #124

    In this episode we delve into the wonderful Objective-C runtime in order to replace method implementations with our own. Using this technique we can add or change behavior to existing classes, which can be extremely useful for Aspect Oriented Programming (logging/benchmarking), or analytics.

  • STHTTPRequest

    #123

    In this episode I take a look at a lightweight network library called STHTTPRequst. Specifically I like two features it provides: easy curl logging of outgoing requests, and a test response queue for performing unit tests against canned responses. Whether or not you want to use this library, there are some good things to learn here.

  • Animating with POP

    #122

    In this episode I cover Facebook's new, shiny animation framework called Pop. With it we explore spring & decay animations that can make your apps feel more alive.

  • Mantle with Core Data Part 2

    #121

    In this episode we continue with our mantle example, this time binding the code to the UI. This involves mapping back to our mantle model for display on the cell, as well as responding to changes using the NSFetchedResultsControllerDelegate protocol.

  • Mantle with Core Data

    #120

    In this episode we cover a different feature of Mantle, which allows us to serialize our models into Core Data entities. This episode continues where we left off in Episode 116.

  • URL Scheme Callbacks

    #119

    In this episode I cover the x-callback-url draft standard, which is an attempt to formalize a way that applications can exchange data back & forth. Using this technique you can have an application expose functionality available to another application. We'll cover parsing URLs to extract out query parameters and how to respond to callbacks in your application.

  • Integrating with 1Password

    #118

    In this episode we talk about adding support for 1Password when creating your login forms. This is an easy technique that can add a nice touch to your applications if you need to support user login.

  • URL Schemes

    #117

    In this episode I cover how you can expose your app's functionality through URL schemes. Inter-app communication is something that iOS is somewhat lacking in, but URL schemes can enable some handy integration scenarios.

  • Mantle

    #116

    In this episode we go over a handy little model framework called Mantle. With Mantle we can easily get support for NSCoding, NSCopying, and JSON serialization for our model objects.

  • Submitting to the App Store

    #115

    In this episode I walk through the process of submitting GiggleTouch to the App Store. Starting with setting the app up to take posed screenshots, requesting certificates, provisioning profiles, and more.

  • Playing Sounds with Sprite Kit

    #114

    In this episode we add looping background music to the game using AVFoundation and AVAudioPlayer. We then add sound effects using Sprite Kit's SKAction. In order to reduce lag, we preload the audio files so that they play instantaneously. We also implement rate limiting to avoid sound effect overload using SAMRateLimit.

  • Giggletouch - Part 2

    #113

    In this episode we continue on building GiggleTouch. This time we improve our random number functions, add a "giggler" node with SKSequence and test on a real device to see what kind of frame rate we get.

  • Giggletouch

    #112

    In this episode I start recreating an old app for toddlers called Giggletouch. In the video I use SpriteKit to render shapes that are subsequently rotated, scaled, and faded. The shapes are drawn with Sketch and random colors are applied to the shape at runtime.

  • Xcode 5.1

    #111

    In this episode we take a look at a couple of new features in Xcode 5.1. The first is creating your own Quick Look representations for custom objects, which can be quite a handy feature for visualizing data (such as images, locations, and paths). The second is a new Autolayout constraint in Interface Builder called "Aspect Ratio" which can further help describe your intent when laying out views with Autolayout.

  • Swipe to Reveal Redux

    #110

    In this episode we fix the problem of a scroll view blocking touches to a UITableViewCell by forwarding touch events from the scroll view and onto a delegate, which manages the cell's highlighted state properly.

  • MDMCoreData

    #109

    In this episode we add Core Data to our Weight Tracker application, but we lean on a new library called MDMCoreData to set up our Core Data stack for us. Using MDMCoreData we can get a sensible parent/child context set up where the main context is a child of the parent writer context. We also leverage a handy class that dovetails with NSFetchedResultsController to display records in a UITableView.

  • Unwinding Segues

    #108

    UIStoryboards can help visualize your screen flow and even describe how to transition between view controllers using segues. In this episode I'll show you how you can take advantage of built-in support to unwind segues to back to where you came from. I'll show the automatic way as well as how to manually unwind a segue.

  • Swipe to Reveal Cells

    #107

    In this episode I customize UITableViewCell to provide swipe to reveal behavior, similar to Mail.app. We use UIScrollView's delegate methods to ensure that we never land mid-way through the swipe, raise notifications to make sure only one cell is open at a time, and we use a help app called Reveal to assist us in visualizing the view hierarchy.

  • UITableViewCell Swipe Action

    #106

    In this episode I cover how to extend UITableViewCells to provide a swipe action, marking an item as read or unread. Combined with a nifty little progress animation, this adds functionality to your table view cells without requiring extra buttons or action sheets.

  • Strong versus Copy

    #105

    In this episode we examine the difference between strong and copy semantics for properties, and why you'd favor copy for types such as NSString and NSArray.

  • Blur

    #104

    In this episode we tackle how to implement an ever increasing trend in iOS 7 app design: blur. We start by doing it the "easy" way using UIToolbar, then move on to a more custom and flexible approach using our own blurred image.
