How to allow both landscape/portrait for tablets only - screen-orientation

I would like to enable screen orientation changes for my application in tablets only, while restricting the layout in phones to portrait only. How do you do this?

In any case, please read this. It should give you an idea as to how to go about it. The <supports-screens> tag allows you to declare what sort of screens you want your app to support. However, if you read this, it'll give you an idea about screen orientation.
Hope this helps.

Invoking application programmatically by text gesture on lock screen - iPhone/iPad

How can i place my application icon on the lock screen of the iphone programmatically(something like the default camera button next to slide lock). Is it possible ? If so can any one guide me on this ??
EDITED
Hi all.. thanks for replies.. after seeing your replies i understand that this is not possible and its possible in jailbroken devices.. or is it possible to invoke my application through some gesture on lock screen ???
I dont think it is possible. I understand you want to implement something like android interface, but apple has its UI standards and has restricted access to that.
For Jail broken Device:
I'm not sure whether it work or not.
Please check these links:

You Tube 2
Note : Possibly it is for Jailbroken devices. Also I didn't checked these video's because it's restricted in our company :(
This is not possible as Apple does not allow that.

How can I fix the webpage orientation to Portrait only for iPad and iPhone?

I have developed a web app/website for the iPad but I can not get it stay in a fixed portrait view only.
I do not want it to rotate and work in landscape mode, because of the way the app has been designed.
I've tried various configurations of the viewport settings but that still has not worked.
I'm not very good at JavaScript so a copy paste option would be best or something in CSS/HTML.
Thanks in advance.
Unfortunately, there is no way to explicitly "lock" the orientation of a web-app in Mobile Safari, as you can also see from the link that Alex posted above in the comment:
How do I lock the orientation to portrait mode in a iPhone Web Application?
However, you can have multiple CSS files for different screen orientations. There's a handy JavaScript snippet that you can copy-paste here:

This should at least allow you to design around the rotation without having to use JS but just CSS.

What is an effective way to deal with iphone orientation change while displaying an image

Disclaimer: I know the question of locking orientation has been asked, and solved. But that's only half my question.
I'm building an iphone website for a small indie game developer. They want to be able to show off screenshots from some of their iphone games. This is somewhat of a problem though. All the screenshots are taken from the game in landscape mode, so it really doesn't make any sense to display them in landscape.
Currently I have a very lightweight lightbox-style display for the image. You click a button on the site, and the image pops up (through ajax magic!) to occupy the full screen. Clicking anywhere on the image makes it go away, as if you had never viewed it.
I'm thinking that the two most practical solutions are either: a) lock iphone orientation for the duration of displaying the image; or b) do some very sneaky rotation on the image when the phone rotates, so no one ever notices. Are either of these possible/feasible? If so, could you give me any tips? And if not, has anyone solved a similar problem?
A demo of this is available at my personal server.
My $.02
As a personal design decision - I would have two images, and switch them as the rotation changes from portrait to landscape. Locking orientation seems so unfriendly. As some extra eye candy, You may want to put some sort of transition image in there between image swaps.

iPhone app 'fake' landscape mode

So after wasting many hours trying to get my app to run in landscape mode by defualt I'm looking for an alternative.
My idea is to create the app in portrait mode but rotate everything by 90 degrees, the player thinks that he is playing the game in landscape mode (when really I've just rotated everything). I recognise it will be a little awkward to develop but I come into all sorts of issues when I try to program for landscape.
My question is, does Apple frown upon this? Could they reject my app for any reason or is this safe to do? Are there any issues I should be aware of?
Advice/articles/help all appreciated.
I do not allow landscape mode in my applications and none of them have been rejected. Sometimes an application does not benefit from being in landscape mode.
EDIT: The same also goes for portrait mode. If your app makes sense only in one orientation or the other, Apple will not reject you.
There is a key you can put into your Info.plist to make it start in landscape (see here). Or have you already tried that?
There are reportedly immersive full screen Open GL games that hide the status bar and do this. Note that you will still need to detect and handle landscape-left and landscape-right rotations or your app might appear upside-down.
Just set an affine transform on your top-level view, and be careful to always use the correct coordinate system.

iPad Orientation Paradigm

I'm not a super awesome designer so this new paradigm has me a little cranky. The iPad is not supposed to have a standard orientation, and should/shall display screen contents at whichever orientation the user decides. This has me sort of stumped. I can keep my UI designed the way I want it in landscape mode, but switching to portrait, I just can't determine the best way to present app content.
I know it's all speculation at this point, but what are the chances we can override the autoRotateToOrientation to only include the orientation of our choice? Apple ignored the HIG on a lot of issues for iPhone, including splash screens, saving state, etc.
I know we can't really argue with Apple, but doesn't it sound slightly ridiculous to reject an app because it won't rotate to portrait?
I've come a long way porting some code to iPad and it works great in landscape mode. I guess only time will tell. What do you all think?
This video: Designing for the iPad from the free Stanford iPhone Programming course might interest you.
If you also registered for the paid iPhone developer program, then I believe there's also the HIG available for the iPad in the site.
Why not design your UI to be fluid? Keep the most important elements high in the hierarchy and let the others flow further down the screen when viewing in portrait mode?
