Is it possible to set a certain iOS app (with whatever necessary user permissions) to launch automatically each time the phone is unlocked?
No. The only ways to start an app are:
from the springboard
through a user acting on a local or push notification posted by your app
from another app using an URL scheme
Not one that will make it to the appstore...

I would like to give a hint to the user, that my iOS app supports the Apple Watch.
So I would like to link/open the Apple Watch companion app from within my iOS app, very much similar to opening the Settings App using ([[UIApplication sharedApplication] openURL: [NSURL URLWithString:UIApplicationOpenSettingsURLString]];)
This shall enable the user to directly navigate to the Watch companion app to setup my app for the watch.
I could not find any URL which would open the companion app in general or specific to a section of the companion app.
If direct linking is not supported, I am also interested in alternative approaches for this use case.
Thanks in advance!
EDIT:
I checked the WatchKitSettings Info.plist file in the simulator to see if it registers any URL schema, but it does not.
I guess it's not possible to programmatically launch the watch companion app from iOS. The opposite way would be possible: to launch the iOS app in the background upon receiving a message from the watch. See WWDC talk Introducing Watch Connectivity.
You could check WCSession.defaultSession().watchAppInstalled and ask the user to launch the app if it is true.
Previously, it was not possible to launch the WatchKit App from the iPhone app, but the iPhone app could be launched—only in the background—with the openParentApplication method.
As of WatchOS 2, however, it is now not possible for either app to cause the other to launch. Instead, there are new methods for queueing changes to be picked up when the other app is launched in the future.
One partial solution for your use case could be displaying a local notification which could be tapped to open the watch app. The primary flaw in such an approach is I do not believe there is a way to limit this notification to the Watch only, so it would also appear on the iPhone where if tapped it would bring the iPhone app to the foreground. Messy if implemented like this, and therefore not worth it I'd have thought, even if it could pass app store review.
I want to launch my application without any click on notification.Is it possible in ios?
No, you can not do it, maybe this can be done on jaibreak devices but it's can not be done on original devices.
It is impossible as of now in iOS devices.
Even it is possible, it is considered as a bad user experience practise.
I built a reminders app, it wont work in background mode, and warns reminders via push notification.
But starting from the moment the User turn off your device (iphone or ipad) and turn on, my app is not this more in background mode, in which case reminders are no longer advised.
In this case, I like to find a way to make my app starts with the device but in background mode (the same happens with windows programs, android apps, and osx programs).
You are focusing on the wrong question. The question you should focus on is, "How do I ensure that my app's reminders will be delivered to my users even after a device restart?"
The answer is to set a Local Notification with a future delivery date, at the point the reminder is created, which of course is while your app is running. There is no need for your app to be running, in either the background or the foreground, for this notification to then be delivered at the specified time.

I have a an iOS7 app running in a Single App Mode on an iPad.
The device is put in the Single App Mode via Apple Configurator.
The Single App mode does not respond to the Home Button.
Is there a way a user can access the device settings when running in a Single App Mode (For example change device brightness or turn bluetooth ON)
Short answer is no.
A device running in single app mode will not allow the user to exit the app to access settings.
A possible solution is to use the Restrictions configuration payload with the autonomousSingleAppModePermittedAppIDs key set to the bundle id for your app.
You will need to install a configuration profile either manually or through an MDM with this payload on the device.
Once the profile is installed your app you can enter single app mode programmatically by calling UIAccessibilityRequestGuidedAccessSession.
You can now add some UI (like a button) to permit the user to exit guided access and launch settings, you exit guided access using the same API to enter it.
Note: This won't force the user back to your app once they have exited your app. You will have to find some other way to do that (ugly hack: force install another configuration profile that brings your app back into single app mode, once that has happened, remove this profile but leave the one permitting it to request guided access).
I would create an iOS application with geofencing.
Can I send a new list of geofencing points to this app through Apple Server in Background or must I launch the app to update its list of points ?
More easily, can I from an external server change the geofence point without launching the app ?
Thanks you very much.
Best regards
Assuming your app doesn't use any of the available background modes, you can't change them remotely. The push notifications are received and shown by the OS, and only opening them will trigger your app to load and execute your code.
