This article is about enhancing the performance of iPhone applications using the power of Objective C++. By discussing a real-world problem from Savoy’s Spots application, the article shows the necessary optimizations to make the program run smoothly in three steps.

Using Objective-C++ on the iPhone application "Spots" to achieve acceptable performance in an intensive graphical application.

Adding the Sounds Code We have an interface that doesn’t do anything. Let’s fix that. The audio framework we need isn’t added by default. We have to add the AudioToolbox framework.

This is an emergency guide to iPhone software development, i.e. a guide for competent developers who haven’t written code for the iPhone platform before, and just want to get started right now.

and that stroke of luck propelled them to the top. Not to take anything away from their hard work, but lots of devs out there are working just as hard on games that are reviewed as well or better.

I started investigating how I might write native iPhone apps from a scripting language. Lua was on my radar already. It’s compact, expressive, fast enough, and was designed to be embedded. Took only about 20 minutes to get the Lua interpreter running on the iPhone. The real work was to bridge Lua and all the Objective-C/CocoaTouch classes. The bridge had to work in two directions: it would need to be able to create CocoaTouch objects and also be able to respond to callbacks as part of the familiar delegate/protocol model.

Lua + iPhone = wax

Bridging a Lua interpreter framework to native iPhone classes -- scripting your way around Objective C. With this week's notice from Adobe regarding Flash development of native iPhone binaries, the options for mobile development are getting more and more plentiful (and more and more abstract).

In the remainder of this post, I’ll walk you through getting it set up, show you how to creating a project featuring a UITableView, and close with a section on its roadmap and tools support.

The "Text" (SMS) application on the iPhone uses a custom, semi-transparent view to show its "Sending..." message over the keyboard. I'll show you a simple class that can display semi-transparent loading messages and how you can display messages over the keyboard.

Loading..." messages When waiting for data loaded from the internet, many iPhone applications use a mostly black, semi-transparent view to block the display. Most use a basic "spinner" (UIActivityIndicatorView) to reassure the user that the application is still running, frequently accompanied by "Loading..." text. Despite the prevalence of this type of loading message, it is not a standard control and must be constructed manually.

You can get most of the benefits of an iPhone application without writing a single line of Objective C. An open source project called PhoneGap lets your wrap your website in iPhone App goodness. And you can even charge for your creation. Even more exciting than being able to easily create an app is getting access to some native iPhone APIs. Currently PhoneGap supports JavaScript access to the user’s location and the device accelerometer. Camera and vibration are still in the works.

There’s talk of being able to use a web form to create your app by submitting only the URL of your website. Currently, it’s a little more work, but easier than creating an app from scratch. You’ll still need to download the SDK and write your app in Apple’s XCode. The PhoneGap wiki has a hello world tutorial that should get you started. One really cool aspect of the PhoneGap project is that it also supports Android and Blackberry. A write-once approach to mobile development is within grasp of the ordinary

The c++ backend for haxe generates standard c++, suitable for the gcc compiler. iPhone dev uses gcc, and can link against c++, which make you think that iPhone dev can use haxe. Simple? Well, actually it was pretty simple. The hardest bit for me was to grok the components of an Xcode project, moving from dynamic libraries to static ones and getting SDL working.

Nobody could argue that the iPhone has been a revolutionary product in the cell phone industry. A fantastic SDK and third-party application support has enabled programmers to release thousands of apps to millions of people around the world. There are some fantastic apps available and many people are making a living from developing for the iPhone. In this “ultimate toolkit”, we’re showing you everything you need to get started; books, tutorials, software resources, screencasts, podcasts, blogs, forums, conferences, software libraries, design kits, icons, and even where to hire a developer if you decide not to go it alone! I hope you enjoy the roundup, and feel well equipped to embark on iPhone development will a full set of resources at your disposal.

Picture Me was a fun little side project to experiment using face detection on the iPhone.  I have a few ideas on where to take this but I don’t have time to work them now.  So for now, it’s free.  And as an added bonus I’m releasing the source code for it in the hope that it will be useful to the iPhone developer community.

For the "when I get asked to do that in a month" file.

For the latest release of Consume, we wanted to include two buttons: one that linked to all our apps on the App Store, and another that let users easily write a review on iTunes. These both seem like common things iPhone developers would want to do, so we decided to share the results of our research. Some of the information contained below is obvious for experienced iTunes users, while other links are rarer.

With tools like Appcelerator's Titanium and some JavaScript programming skill, creating native iPhone and iPad apps is simple. The danger is in not being always on

Designing for the new iPhone 4 resolution.

Here’s a list of tricks and techniques I learned so far. Over time we’ll see more design conventions, but for now it’s just a lot of guesswork.
