Titanium Mobile tips, tricks, and techniques

Don’t create variables you don’t need

We were having a problem in our app where occasionally photos would load only partway. You’d see the top portion of the photo and the rest would be white. In testing, I was not seeing network errors. Nor was memory being exhausted. Listening in on the ImageView’s error event showed no errors being reported. It wasn’t… Read More »

CommonJS modules instead of globals

When you need a value or method to be available in various places in your app, the temptation to use a global variable can be hard to resist. You should resist! Besides, there is a good, and easy, alternative. CommonJS modules are a standardized way to create an easily reusable object. These modules can provide… Read More »

Resolution-specific graphics in Titanium

Working on an app the other day, I came across some complex logic for selecting which graphics to show on an iPhone 5 vs. an iPhone 6 vs. and Android device. While it worked, it didn’t capture all possibilities and frankly, was totally unnecessary. In the end, I replaced 30 or so lines of if-then… Read More »

When you create a new Titanium Mobile project, you cannot enter spaces in the name. Renaming Titanium projects is possible, though a bit tricky. There’s an easier way to solve these problems:… Read More »

Breakpoint debugging an Alloy app

Today’s tip came out of a chat I had with the brilliant Aaron Saunders (@aaronksaunders). Thanks Aaron! First, a little backstory. Appcelerator’s new Alloy framework provides an MVC-like development architecture for your Titanium mobile app development projects. In essence, Alloy is a preprocessor. You create views (in XML and CSS-like files), controllers, and models, which… Read More »

Titanium graphs with a WebView

Got data to graph in Titanium? On its own, Ti doesn’t provide a graphing component. There is an iOS-only module in the Marketplace. But if you also need to support Android or want other graph types, you’re out of luck. Fortunately, we can use the WebView, a suitable HTML graphing library, and some app-level events… Read More »
