推荐答案

好吧，我终于成功了！这是我为所有需要它的人使用的代码:

ok finally I made it ! this is the code that I used for everyone who need it :

-(void)InsertRecords:(NSMutableString *)txt{

    NSString *dbPath = [[[NSBundle mainBundle] resourcePath ]stringByAppendingPathComponent:@"movieData.sqlite"];
    const char *dbpath = [dbPath UTF8String];
    sqlite3 *contactDB;

    sqlite3_stmt    *statement;

    NSLog(@"%@",dbPath);
    if (sqlite3_open(dbpath, &contactDB) == SQLITE_OK)
    {
        NSString *insertSQL = [NSString stringWithFormat: @"INSERT INTO myMovies (movieName) VALUES ("%@")", txt];

        const char *insert_stmt = [insertSQL UTF8String];

        sqlite3_prepare_v2(contactDB, insert_stmt, -1, &statement, NULL);
        if (sqlite3_step(statement) == SQLITE_DONE)
        {
            sqlite3_bind_text(statement, 1, [txt UTF8String], -1, SQLITE_TRANSIENT);
        } else {
            NSLog(@"error");
        }
        sqlite3_finalize(statement);
        sqlite3_close(contactDB);
    }
}
