This is inspired by me incorrectly checking the result of NSFileManager's "- moveItemAtURL: toURL: error:” method. This call is within a block function in a call of NSURLSession’s "- downloadTaskWithURL: completionHandler:”. Said completion handler has a prototype of "void (^)(NSURL *location, NSURLResponse *response, NSError*error)”. Am I supposed to check for success by seeing whether or not “error” is nil, or if whether or not “location” (and/or “response”) is NOT nil?
Unlike some older APIs, NSURLSession’s method arguments that are block pointers do not have those inner functions’ parameters and/or return values fully explained. The URL Loading System Programming Guide does not explain what’s expected of those blocks either.
