Though it's not widely known, you can write native-feeling iOS apps for the iPhone and iPad in JavaScript (+ HTML and CSS).

In this article, I'll explain how to:

strip away the browser chrome (the url bar and button bar);
prevent viewport scrolling and scaling;
respond to multi-touch and gesture events;
use webkit CSS to get the iPhone OS look and feel;
cache the app so it runs without internet access;
get a custom icon on the home screen; and
have a splash screen load at the start.

A short while ago, I discovered that Wii Fit could be used to track my progress as I walked on a treadmill. Wii Fit has a game where you jog in place in front of your TV to travel through a virtual landscape. Instead of bouncing up and down on the floor, I put my wiimote in my pocket, hopped on the treadmill and had a much better virtual exercise experience. And of course this got me thinking: if the wii can track movement, why can't the iPhone do the same?

Each year before Christmas we've put up a buyer's guide listing the best iOS titles of the year. Looking back at the 2009 Buyer's Guide and the 2010 Buyer's Guide, we've come a long way. Below you'll find all of 5 star rated iOS titles, as well as the standout 4.5 star games.

Because of this, we decided to find out how much data a typical Siri user might expect to use in an average month. We carefully watched our data usage while performing 11 different queries through Siri, split between local phone tasks and tasks that required lookups from the Internet. We also performed four dictation tasks. Your milage, of course, will vary depending on the kinds of things you might use Siri for and how often you might do those things. With that said, here's what we found.

Siri has been getting a lot of hype over the past year. It's an as yet unreleased product that aims to be a "Virtual Personal Assistant" (VPA). At the recent SemTech conference in San Jose, I sat down with two of the founders of Siri: Dag Kittlaus (CEO) and Tom Gruber (CTO). I was informed that the product will launch end of summer U.S. time - starting out as an iPhone app, but later other platforms will be supported. The iPhone app will go into private beta July/August time period, then launch in Q4 2009 or Q1 2010.

Casey’s Contraptions came out for iPad only in May. Since then, you and your partner in crime have been working on making it run on the iPhone. That’s 3 months for those of you counting. So what has taken this long? Wasn’t it a straight port? Lots of shared code? Just shrink the images and go? Well…

A report released by the Nielsen Norman Group shows that many iPad apps are confusing users by being too subtle about the gestures needed to navigate them, and some are not sensitive enough to the accuracy limit of fingertips. The authors also found that many companies with perfectly functional websites are wasting their time making a less-functional iPad app.

If this (i)Pawn app from Volumique turns out to be real, it could really change the way some games are played on the iPhone, iPod Touch and the iPad. The game, which is supposed to be available sometime in November, uses a set of physical playing pieces, or tokens, that actually interact with the touchscreen. Now we’ve already seen iPhone-friendly styluses, so that’s nothing new, but what’s really intriguing here is how the app is able to recognize the individual playing pieces.

Unlike most desktop browsers, the Safari browser of your iOS device doesn’t support extensions but you can still add extra functionality to the browser with the help of bookmarklets. These are single-line codes that look like regular bookmarks but slightly more intelligent as they can help you translate sites, find word meanings, make pages more readable and so on – all with a single click.

It took an entire day to get In-App purchases to work.  TOTALLY unnecessary.  Apple’s docs on the subject are worthless, so I figure it’s time for another Coding Help Blog Post

One of my first icon projects for Campaign Monitor was to create a set of Apple iOS icons for our mobile web application. These are the icons that show up when you bookmark our mobile site to the ‘home screen’ on your Apple device. Now, with all of the iOS devices floating around out there, you can do things the easy way by creating one large icon which is then scaled down for that particular device, or you can do it properly by creating a pixel-perfect icon for each device. For the iPod Touch/iPhone 2.5/3G/3GS, the icon size is a miserly 57 pixels square. For the iPad, it’s 72 pixels square, and for the newer iPhone4, it’s a whopping 114 pixels square.

I created a web-based iPad app mainly for my own personal use. I got fed up with the App Store and all the paid apps that didn’t do the trick.

My particular project is a news aggregating app that makes it easy to take 5 minutes every couple hours and keep up-to-date on news stories from a variety of sources.

You’ve been depressed for like a year now, I know. All the hardcore Objective-C developers have been having a hay-day writing apps for the iPhone. You might have even tried reading a tutorial or two about developing for the iPhone, but its C—or a form of it—and it’s really hard to learn.

Matthew Wiggins of mobile developer Wonderland, creator of the chart-topping Godfinger, has claimed that charging any price for an iPhone game is a mistake.

Following the Canada-only release in March, Godfinger went to no 1 in the charts in 36 hours with no promotion. It also topped the charts come its worldwide release in June.

Last week a great blog post, followed by a seemingly innocuous tweet from @mysterycoconut, escalated into what is now known as iDevBlogADay. The concept is fairly straightforward; Every day a developer (or two) will post on their blog. We all have an allotted day so that there is at least one blog post published every day of the week. @mysterycoconut has done a great job of organising it with the #idevblogaday hashtag, a twitter list for the participants, and even an aggregated RSS feed of all the blogs. There’s a wide variety of developers joining in – Scroll to the bottom of this page to see the roster.
