1. Please refer this link for detailed info about iOS application states .

It says :

Non-running - The app is not running.

Inactive - The app is running in the foreground, but not receiving events. An iOS app can be placed into an inactive state, for example, when a call or SMS message is received.

Active - The app is running in the foreground, and receiving events.

Background - The app is running in the background, and executing code.

Suspended - The app is in the background, but no code is being executed.

2. At the time of downloading at dynamic time in app , we need to give path for the detination , that will be of Documents Directory .

Main Bundle is the space where you can add the files initally and ship with the ipa.

Hope this solves your Query.
