Question

I execute a fetch request and i'm eventually getting the managed object . The managed object gets deleted on using [managedObj deleteObject:file] which does not appear in further fetch request . But file remains in the memory .

Answer 1

I did the following [managedObj deleteObject:file] to delete the managed object .

[[NSFileManager defaultManager] removeItemAtPath:filePath error:&error] to delete the file from internal memory.
