Continuing our build out of Road Trip DJ, this time I focus on the music player, and keeping the play/pause button in sync on UIToolbar, which proves to be more difficult than it should be.
In this episode we continue Road Trip DJ and implement the media picker controller, talk about the different modes that in can operate in and how that affects the usability of this app. We also consider how we're going to build a playlist and keep appending items to it.
In this episode we start building an app from scratch called Road Trip DJ. The idea is the build a playlist of music on the fly while it is playing. This is an app I've wanted to build for a while and it serves as a good, small app we can build from start to finish.
Continuing from last week's episode, this time we talk about adding environment-specific settings in xcconfig files, have them pre-processed into the Info.plist, and also how to integrate this technique with CocoaPods.
In this episode we extract all of the settings from a standard iPhone project and move them over to a .xcconfig file for Xcode to use as a base for our projects. Doing so can make our configuration a bit more explicit, allow us to add comments on why certain settings are necessary, and also to put them under version control to make it easy to spot changes.
In this episode I cover configuring your Xcode project to conditionally include or exclude a feature, in case there is a feature you can't have in the App Store, or perhaps something that isn't quite ready yet.
In this episode I take a look at the basics of Cocoa Bindings. With Bindings you can have your controls on your view bound to properties on your controller or model, and even have controls bound to themselves. What would normally be a lot of manual plumbing code is handled for you automatically by bindings. To demonstrate, we build a live-updating temperature converter.
In this episode we take a look at CoreAnimation's easiest form of animation with CABasicAnimation. Using this class we can animate properties of a layer, such as frame, background color, paths for CAShapeLayer, and more. We also cover timing functions and how to make a transition between shapes a bit easier for the system to interpolate between.
In this first episode covering OS X development, I cover how to manage windows, window controllers and xibs with Objective-C and Swift. There are lots of options (and opinions) here, so we follow some advice from Mike Ash's blog post on the topic.
Have you ever wondered how bezier paths work? What are the control points, and how exactly do they affect the line? In this episode we'll build our own visualization of how a bézier path is constructed to help understand it better.
We continue our example of CoreImage CIFilters, this time showing how function composition can facilitate working with filters a bit more flexible and chainable. Starting with the imperative, method-based approach, then gradually building towards a pattern that allows us to easily build filters functionally, swapping out the order, and changing around input parameters.
In this episode we take a look at Core Image, Apple's image framework for image effects on iOS and Mac OS X.
In this episode I revisit the blur technique we covered in episode 104 and re-implement it using iOS 8's Visual Effect view with UIBlurEffect and UIVibrancyEffect.
In this episode we continue our building of a share extension. This time we focus on performing the actual upload in the background, sharing a background session with our application through the App Group capability.
In this episode we create an application and share extension that lets us post to the Imgur API. We use a Framework to share API code between application and extension, and we leverage App Groups so that background sessions transfer across both as well.
In this episode we cover a horribly named, yet fairly powerful concept called flat map. We'll use this technique to solve the problem we discovered last time dealing with Result<T> and having to use a switch statement everywhere.
In this episode I talk about the pattern of communicating errors in Cocoa and how it can be improved by leveraging features in Swift. By introducing a Result type that is generic and applies to any type, it appears useful, however we run into some cumbersome use cases that will require further discussion.
In this episode we use UIKit Dynamics to create something fun: Rope! By attaching many segments together with attachments, we can simulate the physics of a rope. We also discover the best way to move an object on the screen in conjunction with existing attachments.
In this episode we take another look at UIKit Dynamics, this time focusing on UIAttachmentBehavior, which allows you to create springs between elements to fix them in place or make them swing.
One of iOS 8's more powerful new features is App Extensions. With extensions we have a whole new range of possibilities. In this episode we'll focus on the Today Extension, which is a way to add a widget to Notification Center for quick access.
Finally iOS 8 and Xcode 6 are available and out of NDA and we can cover them on NSScreencast. There are tons of new features to cover, so today I'm just going to pick one: IBDesignable. With IBDesignable you can live preview your custom views so you don't have to stare at empty gray boxes in Interface Builder anymore. Interface Builder just got way more useful!
In this episode we explore the powerful UIKit Dynamics that was introduced with iOS 7. With Dynamics you can simulate real world interactions between your views. We'll go over the basics of collision, gravity, rigid bounds, and leave off with an example of why you shouldn't use it to make games.
In this episode we'll attempt to create the board for the game Connect Four. We'll leverage what we've learned about auto layout and create the connect four board constraints, then we'll draw the view. We have to draw it filled with a bunch of holes, so that we can see objects passing behind it. Using Core Graphics and clipping paths we can accomplish this effect.
What good is a static layout? When specifying layout using constraints, we still need to provide transitions and other animations in our interfaces. We can do this quite easily by just animating between different sets of constraints.
