ReactiveCocoa UI bindings with Rex

Today, we will take a closer look at Rex - ReactiveCocoa extensions. I find Rex pretty helpful when working with ReactiveCocoa, especially creating UI bindings.

ReactiveCocoa 4 - CocoaActions

CocoaAction is a wrapper around Action type that is available in ReactiveCocoa. (Here you can read more about Action). We use CocoaAction to bind our Actions to GUI controls. Let’s see a quick example of how it works.

ReactiveCocoa 4 - Events

Understanding signal events in ReactiveCocoa is a must. We can’t effectively use signals and signal producers if we don’t know what will happen after certain event is received. We distinguish two kinds of events that you can send through signals - terminating and non-terminating. There are three kinds of terminating events: Failed, Interrupted, Completed, and one non-terminating - Next.

Open source by default

Using open source code in projects is a common thing. I do it. Most of us do. But what is “open source” by default? Well, I’ve heard about this for the first time at MCE Conf 2016 - “Open by default” panel. It’s an idea to make software open by default and close it only if needed. There are many reasons to close it of course, but sometimes we do it unnecessarily.

Creating an UIImage using ImageIdentifiers

Hi! In my first post I want to share with you some cool tip which I watched in ‘Swift in Practice - Apple WWDC 2015’ Alex Migicovsky presentation about using UIImages in Swift project.

A fast way to connect to the web proxy

Configuring Android device to connect to the web proxy running on development build machine is tedious. You have to make the same steps over and over again on every device you want to debug HTTP traffic.<br/ > It goes like this:

Trust specific certificate on JVM-based platforms

I wrote simple helper which allow loading specific certificate to SSLContext. You can use it to support HTTPS connections which rely on a untrusted certificate. By untrusted certificate, I mean this one which server is certified but system denies it (doesn’t trust it) for some reason. I found it very useful to load particular certificate dynamically.

Fetching contacts with CNContactStore

Since iOS 9.0 we have a new nice method of fetching and saving contacts - CNContactStore! Today I will show you how to create a simple UITextField that will be responsible for fetching a contact for you!

Heartbeat button

Hi! Today I will show you how to create a simple heart button that will simulate a heartbeat upon each tap. You can find an example project on my Github.
