Is it possible to get current lock screen background image in iOS?
I see some apps edit lock screen background.
Can anyone tell about this?
Unfortunately it's not possible. Apple does not allow you to do this. Maybe you can try using some private APIs, but you can not submit your App to the official App Store.

While the application is running in the background, I need to take a screenshot and save it in the photos folder. When I try with Fastlane, it takes only the front of the application. How can I take a screenshot in the background?
It is not possible. Apple allows only few process types in the background, and screenshot isn't one of them.
I need to use the camera in background mode for continuous taking images.but as per apple documentation, we could not use the camera in background mode. Is there any alternate solution for fetching camera without opening application.My task is that When user clicked one button, app should be close and taking images continuously.Could you please any one guide me to do this task?
As the apple documentation say it, it's not possible:
Camera usage is prohibited while in the background.
And I don't think there is any way to do that.
It's good that apple doesn't allow because it increases risk of apps capturing your moments from background without making you notice. Thus risk to privacy.
I want to set the background of my app the same image as it is in the user's iphone lockscreen image, and also I would like to know how to access to homescreen image as well.
Thank you!
Short answer: you can't. Unless there's a public API, things outside your app are blocked.
I don't know of an API to access either of those things.
Is there a way to display progress on Ios App icon on the launcher/ main screen like they have default when installing or downloading an app from App store?
I have content that is being downloaded/uploaded in the background. I want to display continuous progress on app icon.
A circular progress bar is not important. I am just looking if there is any provision for such situations.
This is not possible.
Apple does expose any API methods for adding a layer to the app icon on the springboard.
Also changing your apps icon to include the progress will not work, since the app icon is in your apps main bundle which is readonly.
i don't know if it is still possible to use these red numbers like for whatsapp when you receive a message.
Maybe that would be an idea. You could Show the "%" of the upload/download that way.
I need to check periodically if the camera is obscured or not.
I was thinking of doing this by taking pictures periodically and checking them for brightness, if there is any way to let an App take pictures while the App is in background. Apple does this within it's Find my iPhone system, as I've read (taking randomly/secretly photos of the thief). Is there any way of achieving this within an own App?
Or do you have any other idea how to achieve this?
Not in any way while your app is in the background. Here's a list of services allowed while the app is in the background.
You can only, sort of, check the luminosity while your app is active by calculating it from the images you take. Apple does not allow access to the light sensor to apps yet.
