iOS Cell Registration & Reusing with Swift Protocol Extensions and Generics

iOS Cell Registration & Reusing with Swift Protocol Extensions and Generics

A common task when developing iOS apps is to register custom cell subclasses for both UITableView and UICollectionView. Well, that is if you don’t use Storyboards, of course.

Both UITableView and UICollectionView offer a similar API to register custom cell classes:

public func registerClass(cellClass: AnyClass?, forCellWithReuseIdentifier identifier: String)
public func registerNib(nib: UINib?, forCellWithReuseIdentifier identifier: String)

Ubuntu setup with NGINX http/2 and letsencrypt

Intro

This is a basic collection of things I do when setting up a new headless ubuntu machine as a webserver. Following the steps below should give you a reasonable secure server with HTTP/2 support (including ALPN in chrome) and the fast NGINX server. I am happy to add things so leave a comment.

Basics

After creating the server (droplet on DigitalOcean) log in with

Collections of GStreamer usages

Most GStreamer examples found online are either for Linux or for gstreamer 0.10.

This particular release note seems to have covered important changes, such as:

  • ffmpegcolorspace => videoconvert
  • ffmpeg => libav

Applying -v will print out useful information. And most importantly the negotiation results.
