iPad Development Default Screen Image Orientation

When developing your first app for the iPhone or iPad, you’ll have to provide the app with a default launch screen image. It’s the logo or loading message you would see during any app startup. That startup image is named “Default.png” so by default the devise will automatically display that image during an app startup.

This is not ideal if you’re developing an app with multiple orientations. There are other options. Here are a few recommendations:

Filename Dimensions
Default-Portrait.png * 768w x 1004h
Default-PortraitUpsideDown.png 768w x 1004h
Default-Landscape.png ** 1024w x 748h
Default-LandscapeLeft.png 1024w x 748h
Default-LandscapeRight.png 1024w x 748h
Default.png Not recommended

 

You’ll notice the dimensions above vary in size depending on what orientation the divise is positioned. The deference is 20px taken off the top for displaying the status bar.  You can keep your screen image the full 1024×768 for portrait and landscape if your in a hurry. The OS will trim off the extra 20px on top for you.

There is a known issue for some where, although you have provided both landscape and portrait images, only one will load no matter the orientation. You may want to open your app .ipa file package in a text editor like TextWrangler and locate the “info.plist” file. Once you have it open, cut and paste in the following attributes.

<key>UISupportedInterfaceOrientations</key>
<array>
    <string>UIInterfaceOrientationPortrait</string>
    <string>UIInterfaceOrientationPortraitUpsideDown</string>
    <string>UIInterfaceOrientationLandscapeLeft</string>
    <string>UIInterfaceOrientationLandscapeRight</string>
</array>

 

Apple bans Flash CS5 iPhone App Compiler

Update: Today April 9th 2010, Lee Brimelow, an Adobe platform evangelist responded to the latest poster from Apple with “Go screw yourself “ on his popular web blog TheFlashBlog.com. It’s hard not to notice the frustration of developers across the blogosphere fuel by Apple’s refusal to allow third party API compiled apps in to the iTunes store.

The language from Apple’s agreement states “Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs”. This stipulation is a loathsome move by Apple to render the new Flash CS5 feature of porting Flash files as iPhone/iPad apps totally useless.

I wonder how many flash developers will delay upgrade to CS5 once they get wind of Apple’s stipulation. I’ve noticed a few developers complaining that their apps were rejected because of the use of third party APIs such as Corona, PhoneGap & Titanium

Read the Titanium’s rejection forum post here:

Adobe Flash not on Apple iPad or iPhone

app-shots

Why is it that Apple refuse to assets Adobe in their effort to deploy Flash on iPhones and iPads? Some people believe that Apple fearful that Flash will reek havoc on their battery life. Some think it’s purly profit driven. Think about it. Apple only used Flash on their web site for about a year or two before strictly used QuickTime to handle all of their site’s rich-media content. So they are keep in the same vain by not supporting flash on their Mobile devices.

As a consumer and as a Flash developer, I’m split on this issue. Why? Well I’ve been a Apple user (designer) long before I became a Flash user (developer). Plus I’ve always enjoyed Apple product because they have the tendency of being much more stable than their competitors.

I do feel that Adobe is getting the short end of the stick though. Together, Apple’s OS coupled with Adobe’s creative suits has been such a perfect relationship for those of us in the creative industry. But now with all of the new growth that Apple has had in the mobile sector, they are leaving Adobe to fend for themselves.

The good new is Adobe took some huge steps to remedy this problem by adding a new publishing option in the new Adobe® Flash® Professional CS5. We will now beable to publish AS3 projects files as native iPhone apps. I’m note sure on all the technoligy behine it but they have a few apps up on line now ready for your iPhone… all build using Adobe CS5 beta. Here are a few iPhone applications build using Flash and downloadable via the Apple App Store.
