Should I call setMinimumBackgroundFetchInterval every time the application restarts?

Question

I developed an application that uses background fetching. I set the minimum interval between updates to a minimum:

[[UIApplication sharedApplication] setMinimumBackgroundFetchInterval:UIApplicationBackgroundFetchIntervalMinimum];

I thought that this value is saved by the system, so I do not need to install it again when / if the application restarts. However, I just noticed that the last background download on one of my devices was two weeks ago. I know that the interval between updates can vary, but I do not think that two weeks is normal. Especially considering the fact that it worked for several months, causing a background update every 20-30 minutes.

Unfortunately, I could not find a way to get MinimumBackgroundFetchIntervalto test my theory (does anyone know how to get it, by the way?). I just checked application.backgroundRefreshStatusand it is equal UIBackgroundRefreshStatusAvailable, but I think (I'm not sure) this means that the user allows the application to use background updates.

Well, it turned out that NO, we do not need to call setMinimumBackgroundFetchIntervalevery time the application restarts .
