View controllers tend to play a very central part in the apps we build. This week, let’s take a look at a technique that lets us reduce the size of our view controllers by extracting their core actions, without having to introduce any additional abstractions or architectural concepts.
Ben Sandofsky, the developer behind the camera app Halide, joins John for this season 3 premiere of the show — to talk about designer/developer collaboration, what goes into building a camera app, iOS app architecture, handling dependencies, minimizing an app’s binary size, and much more.
Just like how a UIView can be added to another UIView to form a hierarchy, a view controller can become the child of another view controller. Let’s take a look at how to do that.
While subclassing is not universally bad, avoiding it can in many situations leave us with simpler code that is easier to change and reuse. This week, let's take a look at a few different techniques that can help us write subclass-free view controllers, and how it can help us avoid the Massive View Controller problem.
View controller containment has been an essential part of UIKit ever since the early days of the iPhone. This week, let's take a look at how we can build our own container view controllers, and how doing so can help us make parts of our UI code more modular and easier to manage.
A very common problem when building apps for Apple's platforms is where to put common functionality that's used by many different view controllers. Rather than using a BaseViewController or relying on inheritance in some other way, let's take a look at how we can structure common functionality as child view controllers that can be used as plugins.
