iOS 4 Fast App Switching Explained
Remove Recents Hides iOS Apps That Don’t Support Multitasking
The most important feature of iOS 4 is multitasking and, look, we get it. You’re now able to quickly switch between apps and go back to the exact place you left off the app. It’s cool, and it works good. The problem is, there are too many apps that still don’t support the new multitasking APIs, and it’s kind of annoying to get these apps in the multitasking drawer, tap on them and find out that they haven’t been updated for iOS’ persistent state.
Fortunately for jailbroken users, the solution is in Cydia.

Byline Reaches 3.2 - Brings Background Feed Syncing and Caching to iPhone
We’ve talked about Byline 3 for iPhone before. It’s a great RSS application that features a brand new engine and a good looking UI design. The latest 3.2 update, just approved by Apple and available in the App Store, brings complete iOS 4 support to Byline.
Thanks to iOS’ task completion mutlitasking APIs, the app can now finish the syncing and caching process in the background. Like many other apps though, it can’t fetch feeds on its own. Also, restore state is used to bring you back to the exact location you were before closing the app. Last, Byline now supports the iPhone 4’s Retina Display.

Aves: Web Based Game Engine, Works on iPad and iOS
Aves is a new game engine entirely based on web technologies. It will be used to build 2D / 2.5D videogames running in every browser with modern CSS, HTML and Javascript web standards. It will handle viewports automatically, and - being based on web technologies - the developers promise Aves games will run just fine on the iPad and other iOS, Android and WebOS devices.
But it doesn’t stop at building games with HTML. It’s got some great API stuff we should all look forward to:
“So again, what are action surfaces? As you know, the whole Web 2.0-Idea is actually about sharing and exchanging data using APIs. We have thousands of those in the web today and you can integrate data from Flickr, YouTube, Twitter or Google Maps on your website today by adding a few lines of code.
Guess what? Now you can integrate all those into your games with a mouse click!
If you want to display certain photos from Flickr on an object like a TV-Set you simply tell the Aves Engine that this particular object should have an action surface attached to it and that you want to fill this surface with some data.”
It’s very promising indeed. Check out the official page here, and the demo video after the break. We’ll keep you posted about this.
