The latest post on Ray Wenderlich’s ever-so-useful iOS development site at the time of this writing is What’s New in Objective-C and Foundation in iOS 7, which is the Reader’s Digest version of a chapter from their new iOS 7 by Tutorials book. It gives you a quick look at the following new goodies:
instancetype: It’s the return type that replaces id (and the problems that come with it) in most cases.NSArray::firstObject: Arrays have a lastObject method, and finally, there’s a firstObject method, which gets around the error you get when you try to access element 0 of an empty array.NSTimer tolerances: Lets you specify how late a timer can fire after its scheduled time.NSProgress class: “In essence, NSProgress aims to deliver progress reporting throughout Objective-C code, neatly separating the progress of individual components. For example, if you perform a few different tasks on some data, then each task can monitor its own progress and report back to its parent task.”
NSBrief bills itself as “A brief Podcast for Cocoa Developers, discussing interesting developer-y topics” with 108 podcasts under its belt dating back to October 2010.
Among their recent podcasts are:
My Appventure is Scotty Ruth’s blog chronicling the highs and lows of his experiences developing iOS apps. Lately, his blog has evolved into a podcast series. Here are his latest podcasts:
Now that I’m done installing all 1713 floppies of Windows 8, it’s time to install this game…

I’m in Tampa right now, which puts me well outside Rogers’ regular service area. Since I’m roaming, I always do a happy dance when this happens:

Now that iOS 7 has hit the streets, the non-disclosure agreement that all registered iOS developers is no longer under effect. This means that all of us who’ve been playing with the various beta versions of iOS 7 and Xcode 5 can finally talk about them, as well as their APIs, and their experiences developing for Apple’s new-look operating system. Over the next few weeks, I’m going to talk about as many of the changes to Xcode and iOS as I can, as well as point you to other writers who are covering these topics.
Here’s a look at the iOS 7 reading I’m doing these days:
NSHipster bills itself as “a journal of the overlooked bits in Objective-C and Cocoa”, and it does a good job at that. As with Global Nerdy, they’re going to spend the next few weeks covering what’s new for developers in iOS 7. In this week’s installment, NSHipster covers the following:
NSData Base64 encodingNSURLComponents – “Think of it as NSMutableURL.”NSProgress – “…a tough class to describe. It acts as both an observer and a delegate / coordinator, acting as a handle for reporting and monitoring progress.”NSArray::firstObject – We’ve got NSArray::lastObject, so why not this?CIDetectorSmile – Detects smiling faces within an imageCIDetectorEyeBlink – Detects blinking eyes within an imageSSReadingList – “Even though the number of people who have actually read something saved for later is only marginally greater than the number of people who have ever used a QR code, it’s nice that iOS 7 adds a way to add items to the Safari reading list…”AVCaptureMetaDataOutput – “Scan UPCs, QR codes, and barcodes of all varieties with AVCaptureMetaDataOutput, new to iOS 7.”AVSpeechSynthesizer – “iOS 7 brings the power of Siri with the convenience of a Speak & Spell in a new classAVSpeechSynthesizer..."MKDistanceFormatter – “MKDistanceFormatter provides a way to convert distances into localized strings using either imperial or metric units.”Ray Wenderlich’s site is one of the go-to resources for iOS developer tutorials, from the articles to the books produced by its writers, including their iOS by Tutorials series. They’ve just released the latest in the series, iOS 7 by Tutorials, a PDF book for intermediate and advanced developers that gets updated often and will feature 25 chapters and hundreds of pages of material. This edition covers features such as UIKit Dynamics, Text Kit, background fetch, and the new “flat” design of IOS 7. Highly recommended if you’ve become comfortable with iOS development and want to make the leap past the beginner level.
iOS 7 by Tutorials is available right now for US$54.00.
If you want to get into iOS game development using Apple’s new game framework, Sprite Kit, iOS Games by Tutorials is for you! It’s aimed at developers from all levels, from beginner to advanced.
