Twitter for iPad dev fixes The Daily's UI in 2 hours

Developer Loren Brichter, best known for developing Tweetie as Atebits and now the official Twitter clients for iPhone, iPad, and Mac decided to spend an evening doing what News Corp didn't previous to launch -- fix The Daily's horribly implemented Carrousel UI.

Evening project - The Daily, less slow: 60 fps, full AA, physically correct reflections, (different stacking style).

Hopefully he shares his techniques with The Daily's development team but it just goes to once again show what a difference a great iOS developer can make, even against a huge (old) media empitre. Are you still using The Daily? Video after the break!

Angry Birds for Windows Phone 7? Microsoft Says Yes, Rovio Says No

You're Microsoft and today you're launching the brand new Windows Phone 7 platform and what better game to showcase that launch but iOS hit Angry Birds... unless of course the developer, Rovio, isn't making Angry Birds for Windows Phone 7 and didn't give Microsoft permission to use it. Whoops.

Whether or not Angry Birds will make it to Windows Phone 7 down the road is debatable, but a lot of developers have been contacted and asked to make apps for the Windows Phone 7 marketplace.  In some cases, they've even been offered cash incentives. Hit the jump to see the letter some developers have been receiving from Microsoft asking them to develop for Windows phone 7.

And for complete Windows Phone 7 launch coverage, check out our newly renamed sibling site, WPCentral.

Unreal development kit coming to iOS

Unreal development kit (UDK) is coming to iOS according to an announcement made by Epic Games at the Korean Games Conference.

What this means is that any iOS developer can download the free UDK and potentially start making worlds as breathtaking as Epic Citadel for iPhone and iPad. Once they've gotten accomplished at it, it sounds like it's a short jump -- and business decision -- to becoming an Unreal Engine 3 licensee and exploding across our iOS devices.

Jobs of War, Cupertino Vice, what Unreal Engine games would you like to see?

Game Center slowly coming to life?

Apple's iOS Developer News is letting developers know how to set up Game Center achievements and leaderboard categories:

You can now set up metadata for your Game Center Achievements and Leaderboard Categories in iTunes Connect. Setting up these elements will allow you to test the full capabilities of Game Center for your app in the sandbox environment.

Apple announced Game Center way back in early April but instead of shipping it in June with iOS 4, they said it would be coming "later this year". The basic idea is to give "Xbox live" style social networking to iOS devices like iPhone and iPad.

Do you want your iPhone apps sharpened up for iPhone 4's Retina Display?

Do you want your iPhone apps sharpened up for iPhone 4's Retina Display? iPhone 4 has a whopping 960x480 screen which is literally 4 times (twice vertical, twice horizontal) the pixel size, but the same physical size, as previous generation iPhone 2G, iPhone 3G, and iPhone 3GS. That's a density of over 300dpi -- print magazine quality. Existing apps will just seamlessly use 4 pixels on the iPhone 4 compared to 1 pixel on previous gen iPhones, so they'll look identical.

Twitterrific gets simpler, better for iPad - TiPb at WWDC

Twitterrific is the grandaddy of iOS Twitter clients -- it existed on the iPhone before there was an SDK and was in the App Store on launch day, and again for iPad launch. Twitterrific has evolved from a reader-centric experience to a feature-full client and back to a highly focused app.

Craig Hockenberry, a principle at Iconfactory, the driving force behind Twitterrific, spoke to me at WWDC 2010 about getting Twitterrific ready for the iPad and how that process re-informed what will be going into (and perhaps coming out of) Twitterrific 3.0 for iPhone.

And no, Tweetie becoming the free Twitter for iPhone isn't slowing them down. (You can read more on that from Craig and Iconfactory collaborators David Lanham and Ged Maheux)

Hockenberry has also taken a turn as author, with his iPhone App Development: The Missing Manual now available from O'Reilly. It takes you through the process, from SDK signup to Xcode and Objective-C, to deploying an app. It's a treasure-trove of experience and insight for developers -- aspiring and veteran alike.

Videos after the break. (Huge apologies to everyone, especially Craig, for the annoying wind noise -- I greatly underestimated it during filming)

RunRev responds to Apple's new cross-compiler policy

Apple's new policy on cross-compilers has the development community in a frenzy, and for good reason.  RunRev is reaching out to Apple and developers and voicing their opinion on the matter.

For those not familiar with RunRev, revMobile is a cross-platform solution that will allow developers to port their applications to several different mobile platforms with ease.  Even though revMobile is still in its pre-alpha stages, it shows a lot of promise for developers who wish to develop for multiple platforms.  It allows them to build their applications and not have to re-write code for each and every platform separately.  This would provide an invaluable tool for devs.  Now with Apple bringing the ban hammer down on cross-compilers, Adobe isn't the only one speaking up anymore.
