am getting the folloewing error while converting NSString in to double value.

        NSString *latValue = [retrieving valueForKey:@"lat"];
        double db = [latValue doubleValue];
        NSLog(@"db valiue is %f",db);

retrieving is my NSDictionary. Error:

* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayI doubleValue]: unrecognized selector sent to instance 0x8e83860.

Please help

It is because that the "lat" is an NSArray, not an NSString?
