Find the Last Modified Date of a File in Cocoa

How can I find the last modified date of a file in cocoa?

From stackoverflow

• Check out NSFileManager's

  - (NSDictionary *)fileAttributesAtPath:(NSString *)path traverseLink:(BOOL)flag
  

  the key you're interested in is NSFileModificationDate.

  aussiegeek : This is deprecated in 10.5, instead use - (NSDictionary *)attributesOfItemAtPath:(NSString *)path error:(NSError **)error
