SQLite iOS 插入数据

我试图将一个名称插入到我的 sqlite 文件中。我正在使用此代码，但它不起作用：/

-(void)InsertRecords:(NSMutableString *) txt{
    if(addStmt == nil) {
        const char *sql = "INSERT INTO myMovies (movieName)  VALUES(?) ";
        if(sqlite3_prepare_v2(database, sql, -1, &addStmt, NULL) != SQLITE_OK)
            NSAssert1(0, @"Error while creating add statement. '%s'", sqlite3_errmsg(database));
        else
            sqlite3_bind_text(addStmt, 1, [txt UTF8String], -1, SQLITE_TRANSIENT);
    }
    if(SQLITE_DONE != sqlite3_step(addStmt))

        NSAssert1(0, @"Error while inserting data. '%s'", sqlite3_errmsg(database));
    else
        sqlite3_reset(addStmt);
}

将您的查询传递给此方法并尝试，

-(void)Insertdata:(NSString*)query{

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *databasePath = [documentsDirectory stringByAppendingPathComponent:@"YourDBName.sql"];

    if(sqlite3_open([databasePath UTF8String],&db) == SQLITE_OK)
    {
        NSString *querySQL = [NSString stringWithFormat: @"%@",query];

        char *errmsg=nil;

        if(sqlite3_exec(db, [querySQL UTF8String], NULL, NULL, &errmsg)==SQLITE_OK)
        {
           NSLog(@".. Row Added ..");
        }
    }
    sqlite3_close(db);
}
