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 on the New Goodies in iOS 7’s APIs
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:
NSURLComponents– “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 image
CIDetectorEyeBlink– Detects blinking eyes within an image
SSReadingList– “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 class
MKDistanceFormatterprovides a way to convert distances into localized strings using either imperial or metric units.”
