Difference between iOS 7 and iOS 5.1 App behavior when in background - objective-c

What are the differences in iOS 5.1 & 7.0 in the aspect App behavior when it is in background?
My problem is when switching to other app and switching back (let's say after 5 min / 30 mins) to my app, I am getting server error "connection lost". That was not happening with iOS 5.1, but happening in iOS 7.
I think there is something with the iPad running in the background in different way on iOS 7...
Any ideas?

splashscreen issue with iOS 9.3 but ok with 8.1

My current issue is the following I'm using the "Default.png" nomenclature in order to have a splashcreen following the device's language.
In iOS 8.1 there's no issue (at least on simu 4,4s,5, 5s,6..) but with iOS 9.3 (simu AND device from 5 to 6+), the splash screen doesn't appear and the application has the "size" of an iPhone 4 application.
I'm using the last version of Xcode and the project was an old project (iOS6) upgrade to iOS8 following the client requirements.
Any clue ?
my splashscreens for the following formats
320x480 640x960 640x1136 750x1334 1242x2208

Adaptative layout iOS 8 and iOS 7

I've to develop an app that should work on iOS 7 and iOS 8 devices. I'm using Xcode 6 to develop it and I'm having issue to design the UI. I designed the UI by using the adaptive layout, so when I try to run the app on a device in which it's installed iOS 8 it works great on all display dimension (iPhone 4s, iPhone 5, 5c, 5s and iPhone 6, 6 Plus) as you can see on the following screenshot:
When I try to run it on a device in which it's installed iOS 7 I get some trouble as you can see on the following screenshot:
How I can fix that issue? I need to design another Storyboard that the system should use if it detect iOS 7? I hope you can help me

App runs on iOS7 simulator, but changing simulator to iOS8 it doesn't recognize CoreData store

I have an iPad app, XCode 6, iOS 7, Storyboards and ARC. If I change the target to 7.x, the app works fine on the simulator running 7.0.
However, if I change the simulator to 8.0, the app doesn't recognize the CoreData store created when running under 7.x (the store is still there, just not found when running on the 8.0 simulator.) Also, none of the objects (UIButtons, UITextboxes, etc) show up either!
I don't have iOS 8 installed on my iPad (afraid stuff like this will affect my users), but the question is: just because something doesn't run on the simulator v8.0, does that mean that setting the lowest target to iOS 7, it won't run on the device if it is running iOS 8?
The iOS 7 simulator is on a separate (virtual) machine from the iOS 8 simulator. So any data you created one of these machines, will not be found on the other.

IPhone 5 Compatible application using xcode 4.3.3

I have completed my universal application using xcode 4.3.3 but when I run application in iPhone 5 , my application launches in small screen. I also changed the launched image to Default-568h#2x.png but all in vein. Please help me out , How can i make application for iPhone 5 using xcode 4.3.3?
There is no way to target iOS 6 with Xcode 4.3.3 you need to update to Xcode 4.5 or higher.
To run Xcode 4.5 or higher your mac will need to running OSX lion or higher.
