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. 👌

  • 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.

  • Refactoring View Controllers - Part 2

    #103

    In this episode we wrap up our refactoring of a complex view controller, this time introducing a model, factoring out a new data source class, and more.

  • Refactoring View Controllers

    #102

    In this episode I take a fairly simple application with a single view controller and examine how we can refactor it into more discrete parts.

  • NSPredicate

    #101

    In this episode we look at a powerful built-in Foundation class called NSPredicate. With predicates we can easily filter large collections of data based on values contained in the collection.

  • Particle Systems

    #100

    In our special 100th episode I dive into a fun little class called CAEmitterLayer. Using this class we can create cool particle effects such as fire, water, smoke, clouds, or a fountain of stars.

  • Parsing and Formatting Dates

    #99

    In this episode we cover a basic but fundamentally important topic: dealing with dates & times. Particularly when dealing with an API, dates can arrive in all shapes and sizes. We'll examine some of the common ones, talk about how to parse these formats into NSDate instances, and how to use NSDateFormatter to display them back again as a string.

  • Camera Capture

    #98

    In this episode we grab image data live from the camera on an iPhone 5. We discuss inputs and outputs, image formats, and finally (you guessed it) put a mustache live on each face in the video frame using the face detection techniques demonstrated in Episode 96.

  • Scrolling Nub

    #97

    In this episode I implement a fast scrolling "nub" to assist with scrolling through table views with many entries. The technique was lifted from the Dropbox app and I build a quick prototype of how it works.

  • Face Detection

    #96

    In this episode we dive into CoreImage with a fun feature: detecting faces in photos! We also find the eyes & mouth positions and use Core Graphics to draw on our photo.

  • Fun with iBeacons

    #95

    In this episode we take a look at implementing an iBeacon transmitter and receiver. Using this technology we can detect nearby beacons and range them in order to see how far away they are.

  • Upgrading an Old Project to XCTest

    #94

    In this episode I upgrade the sample app created way back in Episode 4 using Kiwi to Xcode 5 and XCTest. Along the way, we're greeted with a number of warnings & errors that we have to address to get the Kiwi tests to run with XCTest.
