HOWTO: Native iPhone/iPad apps in JavaScript

HOWTO: Native iPhone/iPad apps in JavaScript
More resources On top of the information below, I can recommend a few other resources: Building iPhone Apps with HTML, CSS, and JavaScript is the only book I found that covered everything. I highly recommend it if you're planning on doing serious app development in JavaScript. Making it full-screen Normally, if you press "+" in mobile Safari and then "Add to Home Screen," the icon it creates acts like a bookmark into Safari. To get rid of the URL and button bars, just add a meta tag: This is what my log app looks like when launched from the home screen: Changing the phone status bar You can also change how the phone's status bar is displayed with a meta tag. The values for content are default, black and black-translucent. Preventing scaling If you pinch on a web app, it still responds like it's in a browser and zooms in. You'll almost certainly want to set the viewport width to the device width as well, so that the app shows up at its natural resolution. Preventing elastic scrolling Confused?

How to Test your Local Website Online with Dropbox Learn how you can code your HTML /CSS /JavaScript files on a local computer and still test the site online using Dropbox. Whether you are designing a one-page basic HTML site or are developing a slightly more complicated site that uses JavaScript and jQuery functions, you need to thoroughly test the design and functionality before putting the HTML/CSS/JS files on a live web server. How do you test the files associated with your project? If you are a professional web designer /developer, you’ve probably set up a local server to test the sites on the computer itself but the workflow is a little more tedious for the rest of us. You write the code in a local folder, then upload the associated files to a FTP server and finally, you load these online files in a browser for testing – this code-upload-test cycle may have to repeated multiple time until your site works as expected. There is however an easier way as well that should save you some time. Also see: How to Completely Test your Website

Turning InDesign Files to iPad Apps Turning InDesign Files to iPad Apps by: David Blatner | January 14, 2011 I’ll be speaking at Macworld Expo (San Francisco) in a couple of weeks on the topic of converting InDesign files to the iPad. So I’ve been exploring the various options available. Using InDesign Some solutions let you add interactive features directly within InDesign, and then export a file that can be converted into an iPad iApp. Adobe’s Digital Publishing Solution (DPS): This used to be called the “digital magazine publishing solution” (DMP), but fortunately someone at Adobe came to their senses and realized that it’s useful for more than just magazines. Convert PDF files to iApps Other solutions take a different approach: You export a PDF file from InDesign (or any other application, I guess), then upload that, add interactivity using their proprietary solution (usually through a web browser) and then they convert the file to an iApp for you (or, in some cases, force you to use their app). Other suggestions?

Touch - HTML5 JavaScript Framework for Mobile and Touch Devices - Demos The demo apps require a mobile device to look good.

Tracking Touch Events on the iPad « The HTML Pad February 12, 2010 by thethirdamigo Touch events on the iPad work like they do on the iPhone. You can attach event listeners two DOM elements and have listeners called when an event occurs. Basically what you need to do is : 1) Attach a listener to an element <div id="_mcePaste"><div id="box" style="height:225px;width:225px;background:red;position:absolute"</div><div>ontouchmove="touchMove(event)"</div><div>ontouchstart="touchStart(event)"</div></div> 2) Do something when an event occurs function touchStart( e ) { var box = document.getElementById("box"); box.style.background = "green"; e.preventDefault(); return false; } function touchMove( e ) { var targetEvent = e.touches.item(0); var box = document.getElementById("box"); box.style.background = "yellow"; box.style.left = targetEvent.clientX + "px"; box.style.top= targetEvent.clientY + "px"; e.preventDefault(); return false; } I have created a full working example with source here.

Safari Web Content Guide: Configuring the Viewport Safari on iOS displays webpages at a scale that works for most web content originally designed for the desktop. If these default settings don’t work for your webpages, it is highly recommended that you change the settings by configuring the viewport. You especially need to configure the viewport if you are designing webpages specifically for iOS. Configuring the viewport is easy—just add one line of HTML to your webpage—but understanding how viewport properties affect the presentation of your webpages on iOS is more complex. Before configuring the viewport, you need a deeper understanding of what the visible area and viewport are on iOS. If you are already familiar with the viewport on iOS, read “Using the Viewport Meta Tag” for details on the viewport tag and “Viewport Settings for Web Applications” for web application tips. Read “Layout and Metrics on iPhone and iPod touch” to learn about the available screen space for webpages on small devices.Read “What Is the Viewport?”

How to make a magazine app in iOS – Part II Welcome to the second part of this tutorial. Previous in the series:How to make a magazine app in iOS – Part I The iOS5 revolution A lot of water has flowed under the bridge since our first part of this tutorial. I will not spend my time explaining all the Newsstand features, all in all we’re creating a magazine app here and the Newsstand implementation details go beyond our original purposes. The example app The screenshot shows the final appearance of the app. The full app code is available on GitHub. I have setup this app using the basic single window Xcode template and then added the two main components in the application delegate startup method: The two components are: the Store class, which represents the Store Manager block in the app architecture; this Class is a subclass of NSObject and is not linked to the user interface.the ShelfViewController represents the UI of the application. The app has then been integrated with the new Newsstand requirements in the info plist. Conclusions

Support development If this script saved your day and you wish to support future developments you may consider sending some funds via PayPal or Flattr. Overview iScroll 4 is a complete rewrite of the original iScroll code. While latest Android revisions are supporting this functionality (although support is not optimal), Apple seems reluctant to add one finger scrolling to divs. In addition to all previous iScroll features, version 4 introduces: Pinch / ZoomPull up/down to refreshImproved speed and momentumSnap to elementCustomizable scrollbars Please note that iScroll 4 is not a drop-in replacement for iScroll 3. Also consider that the script is still in beta, and some APIs may slightly change. Getting started In the archive you’ll find plenty of examples to get you started. onLoad

Base64 converter for embeded URI Images Description A script for converting text or images or anything else to and from Base64. Also demonstrates the use of Data:_URL which are useful when attempting to embed images inside of webpages with linking them Convert Text Convert some text from or to Base64 Convert Image Converts an image (under 50k) to to Base64 used in images Where would this be useful? This could be useful when building webpage where you want to include multiple images with having to link to an external document. The advantages are HTTP request and header traffic is not required for embedded data, so data: URIs use fewer network resources whenever the overhead of encoding the inline content as a data: URI is smaller than the HTTP overhead. What is Data:_URL The data: URI scheme defined in IETF standard RFC 2397, is an URI scheme that allows inclusion of small data items inline, as if they were being referenced to as an external resource. Data:_URL [Wikipedia.org]rfc2397 [ietf.org] What is Base64
