NSURLSessionDownloadTask downloadTask: didFinishDownloadingToURL file does not exist?
When debugging an app, since iOS8, file paths change every time you start a debug session (at least in the Simulator).
Check the app-identifier in the path, it sometimes changes when you debug it.
Since iOS8, you should use this for fileURLs:
NSURL *documentsPath = [[[NSFileManager defaultManager] URLsForDirectory:NSCachesDirectory inDomains:NSUserDomainMask] lastObject];In setDownloadTaskDidFinishDownloadingBlock: I use this to return the fileURL where it should save the file:
return [documentsPath URLByAppendingPathComponent:fileName];To open the file:
NSURL *fileURL = [documentsPath URLByAppendingPathComponent:fileName];To delete the file:
NSURL *fileURL = [documentsPath URLByAppendingPathComponent:fileName];NSError *error = nil;[[NSFileManager defaultManager] removeItemAtURL:fileURL error:&error];
