[XCODE]ViewController基本應用 - 點選換畫面（ViewController > ViewController）

swift不需要.m了,因此我們在VC.swift裡面新增

    @IBAction func close(segue:UIStoryboardSegue){

        

    }

就可以了

- 無法將table view controller與code關聯起來

要選到對應的storyboard區域才可以選對應的custom class(BLEScanTableViewCell)

- initializer for conditional binding must have optional type

發問至 stackoverflow

guard類似於if 或者是exception

-Table view controller 參考官網教學

https://developer.apple.com/library/content/referencelibrary/GettingStarted/DevelopiOSAppsSwift/CreateATableView.html

- Int to String

        let x : Int = member.rssi

        let myString = String(x)

-添加TableViewController会出现”Prototype cells“警告

記得要在identify裡面輸入相對應的label

例如  let cellIdentifier = "BLEScanTableViewCell"

-模擬器視窗大小

command + 1~6
