Xcode download db from server

Hello everyone I am creating an app that uses a db to show data , but currently the db read it locally via FMDB . What I want to know is how can I download the db directly from a server and display it in the table view ? thank you all sorry for my english ! This is the code I use to read the db locally :`-(void)viewWillAppear:(BOOL)animated{

NSString *path = [[NSBundle mainBundle] pathForResource:@"Climbing" ofType:@"db"];

FMDatabase *db = [FMDatabase databaseWithPath:path];
if (![db open]) {
    NSLog(@"Error Opening DB");


    return;
}
NSString *queryString;
CDData *regioni;

queryString = @"SELECT * , (SELECT count (*) FROM citta t WHERE t.id_regione = a.id_regione) as city FROM regione a ";

FMResultSet *s = [db executeQuery:queryString];
while ([s next]) {

    regioni = [[CDData alloc] initWithRecordSet:s];


    [self.data addObject:regioni];


}

[db close];

} `
