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.

I need to create sticky button which is on screen like hike button in ios
If i detect that application(WhatsApp) state event so i solve this problem. Thats why i need to create another application launched event.
Thank you in advance.
Apps on iOS are sandboxed and can not directly communicate with other apps directly. There are some API's in the iOS SDK which allows some interaction, mostly audio, share of items.
Apple does not expose to you app if an other app is launched, so checking that an other is launched is not possible.
The second issue is that you can draw on de screen outside of you own apps windows. So you will not be able to draw a button on top of some other app.
I'm fairly new to developing iphone apps and wondering if it is possible to code an app so that user can access the app with homebutton from lockscreen.
For example multiple-taps or long press etc.
Is it possible? and if it is, how am I supposed to code it?
No, this isn't possible. There is no public API to access the home button.
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.
I've seen some apps for example (Vesper, or iPad's reminders app) make use of a user's home screen background image. How is that possible?
It must be some sort of clever trick to make a transparent View or Window or (Gulp!) Private API?
Anyone hazard a guess?
I haven't tried it myself, but I hear that the private method [[UIApplication sharedApplication] _setApplicationIsOpaque: NO] may do what you're after.
iOS 13 beta 1 supports setting UIApplicationIsOpaque to NO in Info.plist. But, it’s not documented so it will maybe be removed or not allowed on the App Store.
is there a way to setup an image as a device wallpaper? Originally I want to download an image, save it somewhere in a picture roll and set it up as a wallpaper programmatically.
google doesn't give me any answer on how could it be done.
Unfortunately this API is not exposed to developers. There is also no URL scheme exposed for developers to launch the Photos app.
You're only option is to display a prompt that tells the user to manually go to the Photos application to set their wallpaper, and indicate how they would set the wallpaper there.
