Hello all, I am trying to download a large file from a server using AFNetworking with NSURLSessionConfiguration backgroundSessionConfiguration. The download start and succeed when app is in foreground. The download process still succeed if the app goes to background. If the device is configured without a passcode, the download still succeed even if the device got locked while downloading the large file. The download process gets interrupted and fails when the device is configured with a passcode and locked. The issue happen with both iOS 7 and iOS 8. Any help is appreciated to solve this issue? Here is the error description that I receive when such failure happen: Error Domain=NSPOSIXErrorDomain Code=1 "The operation couldn’t be completed. Operation not permitted" UserInfo=0x166378d0 {NSErrorFailingURLKey=https://webp.googlecode.com/files/webp-samples.zip, NSErrorFailingURLStringKey=https://webp.googlecode.com/files/webp-samples.zip}
The most likely cause of this is file protection. I posted about this in a thread in the old DevForums.
