Fake iPad Photos

Here’s a handy trick for putting together your iPad app promos:

Maybe you’ve wondered how it’s possible that some people (like Panelfly or even us) have photos of iPads with their apps in them weeks before the devices arrive to the market.

Well, the trick is to take the official photos by Apple and replace the screen content. It’s not difficult but a little tedious, especially getting the perspective transforms right. To save time and effort you can use this Photoshop template that does all the work you. Replace the placeholder images with your screenshots and you’re done!

Flash on iPhone

Okay, all you Flash-lovers, this one is for you.

Flash on iPhone is now a possibility. Sort of.

The Gordon JS library aims to provide a javascript interpreter to replace the Adobe Flash runtime. The advantage is existing Adobe Flash documents will bypass the Flash runtime itself (which is what is banned from the AppStore) and instead directly execute through Javascript, which is allowed…

All our best with that!

Tip: iPad CSS

Here’s a new feature that snuck into the iPad’s version of WebKit: CSS orientation media queries!

Using orientation in CSS is very simple. The code looks like this:

<link rel=”stylesheet” media=”all and (orientation:portrait)” href=”portrait.css”>

<link rel=”stylesheet” media=”all and (orientation:landscape)” href=”landscape.css”>

Yeah, doesn’t get much simpler than that. And it works on non-sucking desktop browsers too, just resize the window narrow to see. Presumably this would be a handy tip for laying out content in your iPad (and no doubt iPhone after the next OS rev) apps via UIWebView and getting orientation changing in a straightforward fashion as well, with any luck.

Particle Designer

Here’s an amusing way to while away some time: Particle Designer 1.1, a tool for designing — and sharing! — particle emitter configurations for the iPhone:


The idea behind this is

… I decided to create a desktop app that would allow you to visually design your particle emitter.

In SLQ the particle emitter is configured using an XML file. The Particle Designer I’m creating allows you to play with all the different settings supported by the ParticleEmitter class and then creates the XML config file. This file can then be used inside your iPhone projects that use the ParticleEmitter class.

This has taken playing with particles to an all new level and I’ve spent WAY too long just playing…

Yes. Yes, indeed, playing with these has a quite remarkably gripping quality to it. Right now that’s all it’s good for actually, you can’t save your designs until the tool goes commercial — but the sheer shininess that this particle emitter stuff adds to your interface is going to make it worth pretty much whatever they charge, we have no doubt!

iPad App Store Sales

It’s always fun to go over some hard sales numbers for the App Store — and here is a really comprehensive look at that:

Revealed: Using Weather HD to Look Inside the iPad App Store’s Sales, and Why Apple May Have Just Created a New Billion Dollar Industry

Having an application, Weather HD, in the Top 10 top-paid list, we wanted to share our early look into how the numbers really are, and what the iPad App Store is shaping to become. We will use our own sales numbers to estimate how everyone else is faring out, and how much the iPad App Store is worth.

They calculate out a spreadsheet of the top 100 paid iPad sales, ranging from 5515 at #1 to 209 at #100; and according to this logic,

Based on the sales and ranks of our very own Weather HD, we estimate that the Top 1,000 iPad paid applications are making about $372,000 per day, which sums up to about $136 million per year. This figure is based on there being only 500,000 iPads in the market, and is accounting only for the application sales in the United States. If the iPad App Store were to be like the iPhone’s, then 40-60% of the sales would occur internationally, so on average that figure would rise to become $272 million per year.

We believe this to be a conservative estimate. If the iPad were to enjoy a lucrative growth as the iPhone’s, which rose from 100 million downloaded applications in the first 2 months to 4 billion 19 months after, we can easily see the iPad’s App Store becoming a $1 billion per year market in 2 years.

… whew, this iDevice development business just looks better all the time, doesn’t it now?

Things To Read

Hmmm, it’s been a few days since we’ve stumbled across anything that struck us as worth making a note of here. Obviously, we are not reading widely enough, are we? Well, courtesy of The Flying Jalapeño Lives, here is what we’re pretty sure is the closest thing on the web to an absolutely exhaustive list of things that we should be following more closely:

Development Links: Redux

Yes, quite the veritable plethora that. Why, it’s so exhaustive it even includes us! And waaay down at the bottom note the handy

And if you would like to add these straight to your favorite feed reader, here is the OPML file:


Lastly, I used this little web app to parse my opml file.

Or if you just change the extension from .xml to .opml it imports nicely into NewsFire for instance, but if you have an RSS reader you like much better hey feel free to share it with us; but whatever you use, that list should ensure that you never run out of iPhone development browsing material when we’ve dropped off the grid!

Source: iPad Dashboard

Here’s your daily dose of niftiness; this clever spark created an iPad version of Dashboard.

Inspired by Apple’s Dashboard application for Mac, Dashboard for iPad has been completely rewritten for iPad. It brings the ability of running multiple mini-applications, widgets, to all iPad users. With access to any of the existing Dashboard widgets for Mac available to download right within this application, you can quickly add several fun and functional widgets to your Dashboard.

Yep, that’s pretty cool alright:

Screen shot 2010-04-14 at 11.13.33 PM.png

Sounds like something you’d find handy, yeah? Well, not in the opinion of Apple. Boo, hiss.

Alas, Cupertino has now rejected the app for “contradicting the iPad’s user experience”, whatever that means…

Cha. Yes, sometimes they are genuinely annoying, aren’t they. But hey, at least you can run it yourself if you like, since the author has been kind enough to opensource it on GitHub!

The Great Section 3.3.1 Debate

So no doubt you’ve observed the great spectacle of frenzy over the infamous Section 3.3.1 (there’s a T-shirt in there somewhere, I know it) of the latest developer agreement:

3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited).

… with reactions from the profane to the pedantic to the metaphysical to the insightful to the whoa, dude.

Rather than weigh in one way or the other on the emo angst surrounding the apparently imminent demise of not only Flash Packager but also Corona and iPhoneWax (Lua), MonoTouch (C#) and theoretically even scriptable engines like Unity, we’d like to draw your attention to the pretty much completely overlooked point of exactly what is explicitly allowed. Specifically, JavaScript.

First observation is that leaving that as an option means you can completely throw out every “it’s all about the money” or “Apple wants to stop cross-platform development” argument immediately. As we’ve mentioned before, HTML5 apps are completely cross-platform, you can avoid the App Store with them, and Apple has gone to a fair bit of trouble to make the offline HTML5 app experience pretty darn close to a native code application experience. So several whole classes of anti-Apple rant are rendered moot right there.

Explicitly blessing JavaScript in this section, though, that seems to imply that frameworks using HTML5 to deploy App Store versions of cross-platform apps is not only tolerated but specifically consecrated. (Given the … fervor … surrounding the issue, religious imagery seems appropriate.) At the very least, it certainly cements the resolve we’ve been mentioning here and there to get familiar with this alternative sooner rather than later. And despite what some commentators are saying, it appears that proudly cross-platform App Store-targeting JavaScript-based frameworks like Titanium and PhoneGap and NimbleKit and Rhomobile [EDIT: Oops, Rhomobile is actually Ruby, they might be out of luck] and other miscellaneous bits are not just allowed, they are actively encouraged.

Indeed, we have word that Apple sees it that way too, at least for PhoneGap:

[ Update:: April 13, 2010 ]

I have received word from Apple that the above is STILL true! If you were concerned by the recent changes to Apple’s iPhone developer agreement, this has ZERO impact on PhoneGap!

Apps built with PhoneGap will continue to be reviewed based on their own merits and NOT dismissed/rejected because they use PhoneGap.

So enough with the crazy speculative rumour mill. Let’s get back to making apps with HTML+CSS+JavaScript.

PhoneGap ftw!

So there you go. You want to develop cross-platform apps, you have one already sanctioned environment and others that look like they’ll probably be deemed equally acceptable to do that. You want to focus on the iPhone, far as I’m concerned Apple is actually doing you a favour by keeping all the Flash gits out of your way. Either way, there is no problem here.

And one last thought for those that are still upset:

If Flash is such a great platform -it’s actually not bad but not that good either- go ahead and develop these killer apps on Android or WinMo7 whenever that comes out. With killer apps being available on competing platforms making a huge difference Apple will simply change the clause and allow you in. They’re not stupid.

Indeed. If you’re absolutely, totally, convinced that this is a bad move on Apple’s part … well you go right ahead and prove that!

SQLite Intro

So you took away from the post on when to not use Core Data that it would be good to get a little more understanding of SQLite, but are finding a dearth of iPhone-focused documentation? Well, has Ray Wenderlich got just the two-part series for you!

In this series, we’re going to show how to make an app that displays a list of failed US banks from a SQLite database.

In this first part of the series, we will cover what SQLite is and why we’d want to use it, how to use the sqlite3 command-line utility, and how to import data programatically via Python.

In the second part of the series, we will cover how to make an iPhone app that reads data from the SQLite database we created, and display data in a table view and a drill down detail view…
