POP - Prototyping on Paper

Design on Paper
Creating wireframes on your favorite notebook. Take your time and sketch your interface carefully. Pen & paper are the best tools. Complicated software only gets in the way.

Take Pictures
Import your sketches by taking a picture. POP automatically adjust brightness and contrast to make sure your sketches are legible and clear.

Create a storyboard by linking your sketches together with "link spots". Press play and simulate your user interface to make sure everything flows correctly.


The Daily is down

Mr. Murdoch said: "From its launch, The Daily was a bold experiment in digital publishing and an amazing vehicle for innovation. Unfortunately, our experience was that we could not find a large enough audience quickly enough to convince us the business model was sustainable in the long-term. Therefore we will take the very best of what we have learned at The Daily and apply it to all our properties. Under the editorial leadership of Editor-in-Chief Col Allan and the business and digital leadership of Jesse, I know The New York Post will continue to grow and become stronger on the web, on mobile, and not least, the paper itself. I want to thank all of the journalists, digital and business professionals for the hard work they put into The Daily."

Another crash reporter? Why?

Because all existing solutions fall short. PLCrashReporter comes very close, but not quite:

It can't handle stack overflow crashes.
It doesn't fill in all fields for its Apple crash reports.
It can't symbolicate on the device.
It only records enough information for an Apple crash report, though there is plenty of extra useful information to be gathered!
As well, each crash reporter service, though most of them use PLCrashReporter at the core, has its own format and API.

KSCrash is superior for the following reasons:

It catches ALL crashes.
Its pluggable server reporting architecture makes it easy to adapt to any API service (it already supports Hockey and Quincy and sending via email, with more to come!).
It supports symbolicating on the device.
It records more information about the system and crash than any other crash reporter.
It is the only crash reporter capable of creating a 100% complete Apple crash report (including thread/queue names)…

A Visual Explanation of SQL Joins

I thought Ligaya Turmelle's post on SQL joins was a great primer for novice developers. Since SQL joins appear to be set-based, the use of Venn diagrams to explain them seems, at first blush, to be a natural fit. However, like the commenters to her post, I found that the Venn diagrams didn't quite match the SQL join syntax reality in my testing.

CocoaHTTPServer is a small, lightweight, embeddable HTTP server for Mac OS X or iOS applications.

Sometimes developers need an embedded HTTP server in their app. Perhaps it's a server application with remote monitoring. Or perhaps it's a desktop application using HTTP for the communication backend. Or perhaps it's an iOS app providing over-the-air access to documents. Whatever your reason, CocoaHTTPServer can get the job done. It provides:

Study: The Four-Year Anniversary of the Apple App Store

This month’s publication discussed the incredible progress of the Apple App Store from launch four years ago through June 2012. Although volumes and especially revenues have increased, the competition has grown much more fierce as well. In terms of volume the height of downloads per app was in June 2010. However, new markets in other countries have grown significantly over the past two years and are now among some of the largest markets, e.g. China, which is already the second largest country in terms of free downloads. Moreover, the revenue more than tripled in the past two years mainly due to the success of free applications that feature in-app purchases. Games and applications in the Newsstand category are highly successful in monetizing via in-app purchases.

UI Automation

There is a known issue when using the performTaskOnHost API in a UI Automation script. If the task being performed with the API outputs excessively (say, thousands of lines of text) to standard out or standard error, the task may deadlock until the timeout is reached, at which point it will throw a javascript exception.The lock() and unlock() functions of UIATarget have been replaced with the lockForDuration() function.Starting in iOS 5 beta 2, you can now trigger the execution of an UI Automation script on an iOS device from the host terminal by using the instruments tool. The command is:instruments -w device id -t template applicationWhen using the cli instruments for UI Automation you can now target the default Automation Template and pass the script and results path into the tool as environment variable options. For example:instruments -w device_id -t /Developer/Platforms/iPhoneOS.platform/Developer/Library/Instruments/PlugIns/AutomationInstrument.bundle/Contents/Resources/Automat…

In-App Purchase Receipt Validation on iOS

A vulnerability has been discovered in iOS 5.1 and earlier related to validating in-app purchase receipts by connecting to the App Store server directly from an iOS device. An attacker can alter the DNS table to redirect these requests to a server controlled by the attacker. Using a certificate authority controlled by the attacker and installed on the device by the user, the attacker can issue a SSL certificate that fraudulently identifies the attacker’s server as an App Store server. When this fraudulent server is asked to validate an invalid receipt, it responds as if the receipt were valid.

iOS 6 will address this vulnerability. If your app follows the best practices described below then it is not affected by this attack.

Apple adds ‘unique_identifier’ to in-app purchase receipts, not UDID, may be related to recent breach

Apple has begun adding a new field to its in-app purchase receipts entitled ‘unique_identifier’. The addition of the field was reported by Macrumors, but contrary to its article, it does not appear to contain a Unique Device Identifier (UDID), something that Apple has been instructing developers to move away from.

Facebook SDK 3.0 Beta for iOS

1. Better user session management: In the past, managing auths, user sessions and tokens was hard. We've spent a lot of time working to make these takes easier for you. This release introduces FBSession, which manages, stores and refreshes user tokens with default behaviors you can override. It uses the block metaphor to notify your app when a user's token changes state.

2. Ready-to-Use Native UI Views: This SDK release includes a variety of pre-built user interface (UI) components for common functions. You can quickly drop them into your apps instead of building each one from scratch or using dialogs. This gives you a fast, native and consistent way to build common features.

3. Modern Objective-C language features support: With Automatic Reference Counting (ARC), you no longer have to spend as much time on memory management. Support for blocks means that it’s now more straightforward to handle sessions and calls to asynchronous Facebook APIs. This, along with inclusion of ke…

Calling Objective-C Methods From JavaScript

The web scripting capabilities of WebKit permit you to access Objective-C properties and call Objective-C methods from the JavaScript scripting environment.

An important but not necessarily obvious fact about this bridge is that it does not allow any JavaScript script to access Objective-C. You cannot access Objective-C properties and methods from a web browser unless a custom plug-in has been installed. The bridge is intended for people using custom plug-ins and JavaScript environments enclosed within WebKit objects (for example, a WebView).

Bad news though: Not (yet) available in iOS, Mac OS only...

OCMock is an Objective-C implementation of mock objects. If you are unfamiliar with the concept of mock objects please visit which has more details and discussions about this approach to testing software.

This implementation fully utilises the dynamic nature of Objective-C. It creates mock objects on the fly and uses the trampoline pattern so that you can define expectations and stubs using the same syntax that you use to call methods. No strings, no @selector, just method invocations like this:

[[myMockObject expect] doSomethingWithObject:someObject];

Corrupt App Store binaries crashing on launch - Fixed

Last night, within minutes of Apple approving the Instapaper 4.2.3 update, I was deluged by support email and Twitter messages from customers saying that it crashed immediately on launch, even with a clean install.

iOS Automated Tests with UIAutomation - summary

Automated tests are very useful to test your app “while you sleep”. It enables you to quickly track regressions and performance issues, and also develop new features without worrying to break your app.
Since iOS 4.0, Apple has released a framework called UIAutomation, which can be used to perform automated tests on real devices and on the iPhone Simulator. The documentation on UIAutomation is quite small and there is not a lot of resources on the web. This tutorial will show you how to integrate UIAutomation in your workflow.

Many JavaScript implementations do not warn against questionable coding practices. Yes, that's nice for the site that "works best with Internet Explorer" (designed with templates, scripted with snippets copied from forums). But it's a nightmare when you actually want to write quality, maintainable code.

That's where JavaScript Lint comes in. With JavaScript Lint, you can check all your JavaScript source code for common mistakes without actually running the script or opening the web page.

JavaScript Lint holds an advantage over competing lints because it is based on the JavaScript engine for the Firefox browser. This provides a robust framework that can not only check JavaScript syntax but also examine the coding techniques used in the script and warn against questionable practices.

Newsstand in real life

The following is required for background downloading to work:
The device must be on WiFi at the time of the push reception. Background downloading will not happen over 3G, nor will the viewer queue it for later download.

Adobe Digital Publishing Suite

We faced the same problem - did anyone out there get background downloading to work when receiving the Newsstand Push Message over 3G?

Sandbox: initiate a Newsstand background download more than once in a 24-hour period

The content of my publication needs to be updated throughout the day. Can I initiate a Newsstand background download more than once in a 24-hour period?

Allowing multiple background downloads for multiple apps would drain system resources, so Newsstand apps are limited to one background download initiated by push notification each day. If you send additional notifications to a device that attempt to initiate a background download, those notifications will be delivered to the device but ignored by Newsstand Kit.

If you want your Newsstand app to deliver breaking news, consider sending an issue via background download and downloading a small amount of additional, up-to-the-minute content when the user launches your app.

For test purposes on development devices only, you can override the built-in limit and initiate more than one background download in a 24-hour period by setting the user default @"NKDontThrottleNewsstandContentNotifications". See Listing 1.

Git Overview

What this isn’t: a Git tutorial. It doesn’t tell you how to set up git, or use it. I don’t cover branches, or merging, or tags, or blobs.
