NSString *error = nil; 
NSPropertyListFormat format; 

NSData *plistXML = [ [NSFileManager defaultManager] contentsAtPath: path];
NSDictionary *result = (NSDictionary *) [NSPropertyListSerialization propertyListFromData: plistXML 
mutabilityOption: NSPropertyListMutableContainersAndLeaves 
format: &format 
errorDescription: &error];
if (error != nil) {
