iPad automatically detects when connected to a screen through 30pin HDMI cable and mirrors the content of its screen to the second screen.
Is it possible to disable the second screen from mirroring without disconnecting the cable?
I would like to have a feature which enables and disables the second screen without disconnecting the cable.
Thanks
The default behavior is to mirror as you note. You can override this by registering to be alerted for screen events. See the docs for Multiple Display Programming Guide for iOS. This will enable you to determine if and what is displayed on the external screen.

I want to share a note in Notability app on my ipad as a white board for an online Zoom lesson.
For that I connect my ipad to my mac through cable, and mirror my ipad screen to my mac using the Zoom application's option of share of ipad via cable.
The ipad's screen is mirrored, namely, appears on my mac (usually, sometimes it doesn't and I have know idea why). However, the ipad's Screen Mirroring window (accessed via the ipad's control center) is stuck in a weird intermediate state: it keeps thinking and does not show any devices, but does show a Stop Mirroring button. In addition, Notability app in the ipad does not recognize the mirroring and does not enable the new presentation mode (but rather keeps showing the Send-to button instead of the display-mode button). For some reason, the mirroring occasionally does work fine, but usually it doesn't, and I cannot replicate what causes it to work.
How can this be fixed?
(My mac, ipad and notability are all updated: versions 10.15.4, 13.4, 9.3.1 respectively.)
I want to use an old iPad to view an ip camera feed. Instead of keeping the iPad on all day, I want to be able to tell the iPad to wake and open the camera viewer application when the camera senses motion. (Not just a small notification on lock screen, I want to be able to view a full screen image of the cameras feed). After a given period of time the iPad would go back to an off/sleep mode. Is this even possible in iOS? Thanks!
Take a look at the "Singe App Mode" and "Background Execution". Choose an event type that can take your device out from background mode, like VOIP. Do not expect the app to be accepted in the public app store.
I want to my computer to be perceived by the iphone as an external keyboard. For example, I connect an iphone to a computer via a lightning cable and run the Pages on the Iphone and my computer starts sending text via the lightning cable and this text is displayed in the pages. The question. What can I read about it?
Already answered here.
What you are looking for is to use your Mac/PC keyboard for inputing text in your iOS devices, which is pretty reasonable since iPhone’s relative small screen doesn’t make for a great keyboard.
This can be done and there are quite a few apps to achieve what you want. You download the app in your PC/MAC and they all work by presenting the hardware keyboard as Bluetooth keyboards, then the iOS device seamlessly connects to it. For example http://www.acrosscenter.com/ or https://www.houdah.com/type2Phone/.
How to show iPhone app icon on lock screen same as camera on bottom left.
Is there any framework required to implement or just go to settings page in iPhone.
How to do it exactly please described step wise.
Thanks in Advance
You might have seen in certain circumstances some app icons are showing up in the bottom left corner of lock screen. That is an iOS 9 feature. that may be because of following reason.
You're near a business or iBeacon that is broadcasting its location and you have a corresponding app installed, such as being near a Starbucks store; drag the icon to the top of the screen to launch that app.
You're able to use Handoff to take over from an app on another device. For example, if you're composing an email message on your iPhone and switch to your iPad, drag the Mail icon that appears on the iPad up to load the message you were working on in the Mail app.
When you insert a headphone jack into the device's headphone port, or connect to a Bluetooth stereo, iOS 9 guesses you want to listen to something and displays the icon of the last audio app you used when connecting headphones or pairing to that particular speaker. Drag the icon up to open that app.

Apart from these, there can be more reasons, like if you are using an application at a particular location/time for few times/days, then iOS will suggest the app once you reach that location or at particular time of every day.
you can't do this kind of stuff from code or from your application. It is apple's restriction. and you can't change it or replace with another app. it is by default camera app.
Im working on an iOS application that supports external displays over airplay, I do most of my testing with the external display option in the simulator, and some on iOS devices connected to macs running various airplay receiver apps.
Im now attempting to support an external display whose size changes, and I don't have access to the the device to test with(And I can't say what the device is).
I've noticed in the documentation for UIScreen the UIScreenModeDidChangeNotification:
Clients can use this notification to detect changes in the screen resolution.
This notification supposedly gets triggered for the device i'm trying to support, and it seems this is where I should handle resizing the UI to respond to this change.
Are there any ways to simulate an airplay display that can be resized, and on resize will post a UIScreenModeDidChangeNotification notification?
Many displays support multiple resolutions. When the resolution changes on the display it will re-negotiate the new resolution with the iPad and the notification will be triggered. Try changing the display's resolution while the iPad is plugged in via a video adaptor.
