XCode iOS simulator is case insnsitive. iOS on Device is not.

We have an iPad app. We load images using file paths into the app. Images appear just fine in the iOS simulator. Images do not show up on the device. Fist shaken madly in the air, agony.

Thanks to my colleague Dolphy Fernandes we managed to discover the culprit. The iOS Simulator used by XCode loads file in a case insensitive manner. To it, a file called A55.jpg and a55.jpg are the same. iOS on devices, on the other hand, is case sensitive. Hence, A55.jpg will not load if the file name you are attempting to load is 'a55.jpg'.

Hope it helps…

Why keep HTML5 open when you can make it proprietary?

Say what you will, this is pretty cool – at least at the idea level: a specialized, HTML5 web browser for mobile devices that provides special hooks for HTML5 apps granting them access to native device features. Pretty nifty, right? Naturally the people who control the platform, kinda get to decide what can and cannot run, maybe get a cut of the action for the business that they are generating for you and for the work that they invested in making and marketing the app.

In exchange for openness, you get cool features (especially for games) and capabilities you otherwise will not be able to provide. Tradeoffs tradeoffs. Still, pretty darn cool.

mobiUs … the world’s first HTML5 Web App browser.
