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. 👌

  • Making a Custom Subscribe Button

    #394

    Making a Podcast App From Scratch

    In this episode we customize our call-to-action Subscribe button. Using @IBDesignable and Interface Builder we can preview how it looks in the various button states without having to recompile and run in the simulator every time.

  • Adding a Flash Toggle Camera Control

    #304

    Camera Capture and Detection

    In this episode we extract our camera preview layer into its own view so we can add subviews. We’ll use this to add a flash button control to the UI, which will require us to learn about locking the device and controlling the camera’s "torch".

  • Pin Input

    #255

    Sam Soffes walks us through an elegant way to handle 4-digit PIN input, for cases where you have a software lock screen to your app, or perhaps a 4 digit confirmation code is sent to you via SMS and you need to type it in to continue. Often this type of thing is done with four text fields side-by-side, with awkward delegate implementations to manage focus, etc. Instead, Sam shows us how to leverage the UIKeyInput protocol and create a much cleaner implementation.

  • Designing a Custom Download Button - Part 2

    #243

    Large File Downloads

    Wrapping up our custom download button, this time we focus on the highlighted image and depressed state of the button, as well as transitioning to and from the progress layer.

  • Designing a Custom Download Button - Part 1

    #242

    Large File Downloads

    In this episode we create a custom control to serve as our download button. We start by creating a circular progress indicator using CAShapeLayer, then move on to subclassing UIControl to provide our image view and touch handling.
