IOS Sqlite3 Passing Opened database to a method - ios

Question

Using php for an example:
$conn = new mysqli('localhost', 'xxx', '123456', 'xxx');
Just define $conn once, I can pass $conn to all other methods, so that i don't need to repeat the connection again when I run another query, and it's a lot faster.
function example($conn) {
// do some db stuff here
}
Can I do the same thing in IOS sqlite3? Many thanks for helping.
- (void) syncScale {
// Get the documents directory
dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = dirPaths[0];
// Build the path to the database file
databasePath = [[NSString alloc]
initWithString: [docsDir stringByAppendingPathComponent:#"ALDI.db"]];
const char *dbpath = [databasePath UTF8String];
sqlite3_stmt *statement;
NSString *postSetting ;
postSetting = [NSString stringWithFormat:#"scaleData={\"scaleDB\":["];
if (sqlite3_open(dbpath, &contactDB) == SQLITE_OK)
{
NSString *querySQL = #"SELECT * From Table1";
const char *query_stmt = [querySQL UTF8String];
if (sqlite3_prepare_v2(contactDB, query_stmt, -1, &statement, NULL) == SQLITE_OK)
{
while (sqlite3_step(statement) == SQLITE_ROW)
{
// do something here
}
sqlite3_finalize(statement);
} else {
NSLog(#"Steps Data not found");
}
sqlite3_close(contactDB);
}
}

What I usually do, is that keep the opening of database in separate block/function with a boolean return ,rather finalize and rest the sqlite statement; Since the opening of database is made of almost static contents, the function doesn't need any parameters
