从.db文件中删除SQLite数据并使用Swift更新UITableView

Question

我正在尝试使用swift从sqlite表中删除数据并删除UITABLEVIEW CELL的内容。

下面显示的代码工作正常（没有错误）。但问题是，下次运行应用程序时，它会填充先前sql查询中的数据。

@IBAction func removeAllData(sender: AnyObject) {

           //deleting the data from arrays responsible for updating the labels in UITableView Cell

            self.endData.removeAll()
            self.startData.removeAll()
            self.driveData.removeAll()

        //Deleting the table
        let tripsDB = FMDatabase(path: recievedDatabasePath as String)

        if tripsDB.open(){
            let sqlQuery = "DELETE  FROM trips"
            let results : FMResultSet? = tripsDB.executeQuery(sqlQuery, withArgumentsInArray: nil)

            print(tripsDB.lastErrorMessage())

        } else {
            print(tripsDB.lastErrorMessage())
        }
        tripsDB.close()

        self.tableView.reloadData()
    }

任何建议都会有所帮助。非常感谢。

更新

let filemgr = NSFileManager.defaultManager()
let dirPaths = filemgr.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)
databasePath = dirPaths[0].URLByAppendingPathComponent("trips.db").path!



//sending the database contents to table view controller. here the recievedDatabasePath Variable is equal to the current database path mentioned in the first view controller


override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) 
{
   if  segue.identifier == "historySegue" {         
     let destinationViewController = segue.destinationViewController as! HistoryTableViewController
    destinationViewController.recievedDatabasePath = databasePath
        }
     }
