iOS 9 Storyboards Tutorial: What’s New in Storyboards?
// Ray Wenderlich
Note from Ray: This is an abridged version of a chapter from iOS 9 by Tutorials, to give you a sneak peek of what’s inside the book, released as part of the iOS 9 Feast. We hope you enjoy!
Storyboards have been around since iOS 5 and have received lots of upgrades and new features since then, including unwind segues for reverse navigation, universal storyboards for both iPhone and iPad, and live rendering of views designed in code.
Xcode 7 brings new features for storyboards that let you do the following:
- Refactor a single storyboard into multiple storyboards and link them visually via storyboard references.
- Add supplementary views to a view controller using the scene dock.
- Add multiple buttons to a navigation bar, right from the storyboard itself!
In this iOS 9 storyboards tutorial, you’ll learn how to use storyboard references and supplementary views. You’ll be updating an app designed to help you with all those listable moments in life, whether it’s grocery shopping, packing your luggage for vacation, or a survival checklist for the impending zombie apocalypse! :]
To get the most out of this tutorial you should have some basic storyboard and table view knowledge. Need a quick brush-up? Check out our Storyboards Tutorial in iOS 9.
Download the starter project for this tutorial and run it in the simulator; tap one of the displayed checklists to view the items contained within, then tap any entry to check it off. Done and done!
An Introduction to tvOS Development
// Tuts+ Code
At their annual September event for 2015, in addition to new iPhone and iPad models, Apple announced their long-awaited update to the Apple TV set-top box. This new, fourth generation Apple TV includes a powerful A8 processor, a Siri-enabled remote, a revamped user interface and, most importantly, a brand new platform for third party applications and games, which Apple has named tvOS.
In this tutorial, I am going to introduce you to tvOS development by creating a basic tvOS application. This tutorial requires that you are running Xcode 7.1 or later, which includes support for tvOS. I am also assuming that you are already familiar with iOS development.
via How to Create a Framework for iOS 8 on Xcode 6 – Insert.
The internet is full with documentation about how to build an iOS framework. However, when we began our internal development here at Insert, we still had to overcome some non-trivial challenges before we were able to get our SDK working the way we wanted.
Additionally, in xcode 6, Apple dramatically changed the way developers create and build frameworks, so a lot of the documentation you’ll find on the Internet is not up-to-date.
In this post we’ll show you, step-by-step, how to create and build a framework for iOS 8. The framework source code in this tutorial is available on Github.
We will also address important challenges such as:
- How to combine Swift and Objective-C code within the same SDK?
- How to build the framework for the all the relevant architectures (armv7, armv7s, arm64, i386), etc. If you just need the solution for this one you’ll need to add a new Build Phase to your project and use the “run script” at the bottom of this post.
In our example we will use a Manager to enable\disable the Framework and a CustomView Class which will contain (surprise) a custom UIView. In this example we want to show you how how resources such as xib and png files can be integrated within the framework.
via Code Coverage for iOS (Xcode 7) – NSBogan.
I’ll start with back reference to another post I wrote earlier, which describes the process of getting code coverage reports using good old
To try out the old approach checkout this repository and run the scripts.
via Base Lab Blog | Testing Performance with Xcode – Base Lab.
In Apple’s ecosystem, Performance Engineering is often associated with hours spent with Instruments. Time Profiler, Leaks, Allocations, Core Data are all tools that provide us with precious bits of information such as where bottlenecks lie, what uses up system memory, which query takes too much time, etc…
Unfortunately, in my experience (and from bits of information I get from fellow devs), it seems that we reach for Instruments only when we know that something needs to be fixed, or improved. This kind of Performance Tuning should be preceded by proper Performance Testing – and that’s precisely the topic, that I would like to cover today.
via First steps with the Mapbox iOS SDK | Mapbox.
Mapbox Mobile is our vector maps library for mobile platforms. This guide will walk you through installing the Mapbox iOS SDK using CocoaPods and Xcode to load a map, place a pin on it, and change the map style. This guide supports Objective-C and Swift.
Heads up! We’re still actively developing Mapbox Mobile and will update this guide and add new ones as we improve its amazing features.
