i really do not know about doing this.Any suggestions and sample code are much helpful and appreciated.

Answer 1

The simpliest way you can do this is:

- (NSArray *)selectObjectsWithBeginDate:(NSDate *)dateBegin endDate:(NSDate *)dateEnd {
    NSMutableArray *selections = [NSMutableArray array];
    for (CustomObject *obj in objectArray) {

        if ([obj.date compare:dateBegin] == NSOrderedDescending && [obj.date compare:dateEnd] == NSOrderedAscending) {
            [selections addObject:obj];
        }
    }
    return [NSArray arrayWithArray:selections];
}

You just need to be able ti compare two NSDate objects.
