I want to know that does apple approves application having any two of the orientation?
Like Landscape Left and Landscape right ,
Or Portrait mode and Portrait mode Upside down,
My application is having functionality of Drawing and to shows number of images .
Is it only required or I need to use all orientation for the application.
I had put only one orientation and application was rejected but I came to know from some sources that apple allows any two of the orientation , Is it true?
Thanks in advance.
Judging from the thread in the comments below I think you need to support at least 2 rotations. So Both portraits or both landscape or all 4 rotations.
(in my opinion, if your app is landscape you must support both rotations, if it's portrait Apple may be more accepting if you don't support portrait upside down)
Apple require that for iPad you must support all orientations. That's just fact, and there is no possibility to do anything with that.

Scenario: I set the default device orientation to portrait. However, there are some Views that I want to allow for landscape mode.
Most of my views don't need to be in landscape. But there are some with orientation detection that allows a full-size linear graph to be displayed in landscape mode.
I want my application to behave as a Portrait-Centric for most of the time.
Question: How do I freeze the Portrait when I need to, but allow for Landscape when the situation warrants it?
You can manually allow, and most importantly in your case, disallow device orientation through UIInterfaceOrientation. Full description was already answered here: https://stackoverflow.com/a/40859280/13296047
Technical Note TN2244: Launching your iPhone Application in Landscape states:
The values of the UISupportedInterfaceOrientations key determine how the status bar is positioned while the the app is launching. In iOS 7 and below, if the UIInterfaceOrientationPortrait value is present, the status bar will always be positioned for portrait orientation. Otherwise, the status bar will be positioned according to the first orientation that appears under the UISupportedInterfaceOrientations key.
So in iOS 8 it was perfectly fine to put UIInterfaceOrientationLandscape first in the UISupportedInterfaceOrientations list to have your app to start in Landscape.
It does not work anymore in iOS 9. Having UIInterfaceOrientationPortrait in the list at any position forces app to start in Portrait.
Question
Is there a known workaround for this? I need my app to start in Landscape.
Note: Using viewControllers' supportedInterfaceOrientations() method is not an option as it takes effect after the LaunchScreen is presented.
Having UIInterfaceOrientationPortrait in the list at any position forces app to start in Portrait.
That is absolutely correct — very good detective work. It took me a lot of experimentation to figure this out! This is certainly a huge change from iOS 8. You have summed up the situation very well.
Fortunately, the workaround is simple. In your Info.plist, include only the two landscape orientations. Now the app will launch into whichever one is first.
Now implement application:supportedInterfaceOrientationsForWindow: in the app delegate to return All. That way, when the time comes to show a portrait view controller, it will be legal to do so.
In other words, think of the Info.plist as what the launching app needs to know, and application:supportedInterfaceOrientationsForWindow: as what the running app needs to know.
I want to design a universal app that I'd want to support just portrait orientation. It's weird because Xcode allows you to select portrait orientation only in the target's Deployment Info settings (and in Info.plist), but reading the iOS Human Interface Guidelines, in the section regarding the launch images, I've found this:
You must provide at least one launch image. Typically, an iPhone app includes at least one launch image in portrait orientation; an iPad app includes at least one launch image in portrait orientation and at least one launch image in landscape orientation.
Does that mean that you have to provide a launch image in landscape orientation even if you only support portrait orientation? Or is it required to support landscape orientation in iPad?
Thanks
EDIT: It looks like it is not required to support both portrait and landscape orientations in iPad, though strongly recommended. However, it looks like, if an orientation supported, also the opposite one should be (portrait and upside-down, for instance). Is it required then to provide both launch images? (portrait and upside-down). Thanks again
It is strongly recommended that your application support all orientations. This includes portrait, portrait upside-down, landscape left and landscape right. iPad apps that require an orientation must support both variants of that orientation.

My ipad app only runs in landscape orientation. But when I test on an actual device (not the simulator) it always seem to start in one particular landscape orientation, then turn 180 degrees to match the current physical landscape orientation. So, it seems to start in LandscapeLeft(I think) then rotate 180 if I have it in LandscapeRight. There's nothing in Info.plist to set the initial orientation.
Can anyone suggest a way to detect current orientation before view loads and set it to correct landscape view before showing?
Thanks

There is the UIInterfaceOrientation~iPad key which sets the initial interface orientation on startup.
There is also the UISupportedInterfaceOrientations key which informs the app which orientations are supported.
There is no way, however, to make the app start in the current orientation of the iPad.
Have you looked into these questions?
Get current orientation of iPad?
iPad launch orientation
Also, technically, the iPad should just do it. Make sure you have supported orientations set properly, as I'm sure it checks those to see where it should start.
Might be possible duplicate of :- iPad Application Comes Up in Portrait Orientation After Screen Unlock Regardless of Orientation on Screen Sleep but it does not provide any solution.
My problem is I am working in landscape mode on iPad and I locks my screen. After that when I unlocks, my screen first switch to portrait mode and then to landscape mode.
I don't know why it first switch to portrait mode.
Please if any one has face this problem before or know how to sort out this, help me .
Thanks in advance.
Any suggestions will be highly appreciated.
In your Info.plist file, make sure that UISupportedInterfaceOrientations~ipad (or UISupportedInterfaceOrientations) exists and has the portrait and landscape orientations your app supports are listed.
