    Setting Up Push Notifications on iOSPreview image@2x
    151 shares
    Apple originally introduced push notifications to enable applications to respond to events if the application isn't running in the foreground. However, the operating system and iOS devices have changed significantly during the past few years and applications don't need to rely solely on push notifications to perform tasks in the background. This doesn't mean that push notifications are no longer useful though. Let me show you how to set up push notifications on iOS in less than ten minutes.Read More…

    10 Xcode Plugins for iOS DevelopmentPreview image@2x
    273 shares
    A proper plugin architecture can mean all the difference for an integrated development environment. Sublime Text and TextMate are great examples. Did you know that Xcode also supports plugins? It wouldn't surprise me if you don't, Apple hasn't put much effort into advertising that part of Xcode. In fact, there is very little documentation available to create plugins for Xcode. Fortunately, this hasn't stopped developers from creating plugins for Xcode.Read More…

    Core Data from Scratch: MigrationsPreview image@2x
    105 shares
    In the previous articles of this series, we've encountered an annoying issue that we need to address. Whenever we modify the data model of a Core Data application, the persistent store becomes incompatible with the data model. The result is a crash on launch, rendering the application unusable, a serious problem if this happens to an application in the App Store. In this article, we aim to solve this issue by leveraging Core Data migrations.Read More…

    Core Data from Scratch: NSFetchedResultsControllerPreview image@2x
    145 shares
    In the previous installments of this series, we covered the fundamentals of the Core Data framework. It's time we put our knowledge to use by building a simple application powered by Core Data. In this tutorial, we'll also meet another star player of the Core Data framework, the NSFetchedResultsController class. The application that we're about to create manages a list of to-do items. With the application, we can add, update, and delete to-do items. You'll quickly learn that the NSFetchedResultsController class makes this very easy to do.Read More…

    Core Data from Scratch: Relationships and More FetchingPreview image@2x
    71 shares
    In the previous article, we learned about NSManagedObject and how easy it is to create, read, update, and delete records using Core Data. However, I didn't mention relationships in that discussion. Aside from a few caveats you need to be aware of, relationships are just as easy to manipulate as attributes. In this article, we will focus on relationships and we'll also continue our exploration of NSFetchRequest.Read More…

    With everything about Cora Data data models still fresh in your mind, it's time to start working with Core Data. In this article, we meet NSManagedObject, the class you'll interact with most when working with Core Data. In this tutorial, you'll learn how to create, read, update, and delete records. You'll also get to know a few other Core Data classes, such as NSFetchRequest and NSEntityDescription.Read More…

    WWDC 2014 AftermathPreview image@2x
    63 shares
    WWDC is like Christmas for Cocoa developers, and this is certainly true for this year's edition due the scarcity of leaks and rumors leading up to the conference. Even though we're all curious to hear what Apple has in store for everyone loving Apple, the keynote is much more fun when you have no clue what's about to be announced, like this year. If you've seen Tim Cook's keynote, then I'm sure you agree that Apple surpassed everyone's expectations. Let's take a few minutes to summarize what Apple has announced, what it means for developers, and what you can expect later this year.Read More…

    Having Fun with YOLOKitPreview image@2x
    19 shares
    Enumerating collections in Objective-C is often verbose and clunky. If you're used to Ruby or worked with Underscore or Lo-Dash in JavaScript, then you know there're more elegant solutions. That is exactly what the creators of YOLOKit thought when they created this nifty library. YOLOKit's tagline is Enumerate Foundation delightfully and they mean it.Read More…

    Core Data from Scratch: Data ModelPreview image@2x
    67 shares
    In the first article of this series, we learned about the Core Data stack, the heart of a Core Data application. We explored the managed object context, the persistent store coordinator, and the managed object model. This article focuses on the data model of a typical Core Data application. We zoom in on Xcode's data model editor and we take a look at entities, attributes, and relationships.Read More…

    iOS Fundamentals: Frames, Bounds, and CGGeometryPreview image@2x
    108 shares
    Working with CGPoint, CGSize, and CGRect structures isn't difficult if you're used to a language that supports the dot syntax. However, programmatically positioning views or writing drawing code is verbose and can become difficult to read. In this tutorial, I'd like to clear out a few misconceptions about frames and bounds, and introduce you to CGGeometry, a collection of structures, constants, and functions that make working with CGPoint, CGSize, and CGRect that much easier.Read More…
