while of properties nsimage or cgimage, i'd take @ imageio.framework.

to file metadata can use nsfilemanager's attributesofitematpath:::

nserror* error = nil; nsdictionary* fileattributedict = [[nsfilemanager defaultmanager] attributesofitematpath:imagefilepath error:&error]; nslog(@"creation date:%@\nmodification date:%@", fileattributedict.filecreationdate, fileattributedict.filemodificationdate);
