NSFileManager: Copy a file atomically?

Question

in my iPhone projects, I am currently copying files using NSFileManager 's -copyItemAtPath:toPath:error: method. However, the docs so not say anything about atomicity, so I might run into trouble if my app tries to read a file that is currently being replaced by another thread. Is there a way to copy or replace a file atomically? I am searching for something like NSData 's -writeDataToFilr:atomically: .

How do you use NSFileManager ? According to the docs , it says the following:

In iOS and Mac OS X v 10.5 and later you should consider using [[NSFileManager alloc] init] rather than the singleton method defaultManager . Instances of NSFileManager are considered thread-safe when created using [[NSFileManager alloc] init] .
