Question

Right now I am working on an iOS app that needs NSFileManager but when I do the attributesOfItemAtPath: method, it returns null. This also fails on NSData and the dataWithContentsOfFile: method. I do not understand why this is happening. The file URL that I am using looks something like this :file://localhost/private/var/mobile/Applications/597DE145-33D7-4F92-AE95-029D5CF15291/tmp/Kv7DWqtRWH7WnN47HdDW.I suspect it might be something to do with the URL, but I am not sure.

You need to convert the NSURL to a path for use with any of the NSFileManager methods that take a string. Do this by calling the path method on the URL.

NSURL *someURL = ... // some file URL
NSString *path = [someURL path]; // convert the file:// URL to a file path
NSDictionary *info = [[NSFileManager defaultManager] attributesOfItemAtPath:path];
