But that’s not the only need for the update. Mashable.com
reports a smaller update to Facebook for Android was also issued. While not as far-reaching as the iOS update, the Android app now supports faster photo uploads and emoji in messages
points out additional features
Another feature is that Likes and comments are now displayed in real time, as opposed to requiring a refresh as they did in the HTML 5 version of the app. Mick Johnson, product manager of the Facebook apps for iOS tells 'The Times' that the improvements to the news feed make it "feel alive."
Facebook users top complaints about the previous version were slow and sluggish launch of the site, problems with photos loading and too much lag time between new stories showing in the feed.
The new app is “two times faster because it’s built on Objective-C not HTML5
Content is cached between views, all the features of the Messenger standalone app are now built in, a drop-down “new stories” banner alerts you to fresh news feed content in real-time, and a Facebook for iPad app update lets users view Timeline
John Constantine of TechCrunch writes, ‘Facebook’s iOS mobile product manager Mick Johnson tells me that “We feel the pain points [regarding slowness] pretty harshly ourselves…so this major update to the Facebook for iOS app is focused on one thing — speed.”
Johnson explained to me why the app felt so sluggish until now. “We deliberately made a trade off to get to scale. We used HTML5 to test and try things out, and people love that in the browser, but they have different expectations of a native IOS app. So with this release we rebuilt the app from scratch over the last 9 months and the main improvement is performance. Now there’s a lot more code built in Objective-C than HTML5.”
iOS v5 is available for download directly from the App Store
