※ 引述《hpuser (HpUser)》之銘言：
: 請問各位先進:
: 舞台上有一個自訂的button，移過去會變大，移出去會變小,
: 如要實作puremvc，就要 把這個button註冊給一個mediator,
: 由這個mediator來控制變大變小的效果.
: 可是因需要，場景上會動態增加多個button，甚至更多，
: 難道要一個一個註冊給mediator嗎?
: 有沒有可能 我只要註冊這個自訂button類別給mediator，
: 一次就可以了,或是更方便的作法?
: 看教學,view物件似乎都是舞台上已經存在的實體居多，
: 沒看過註冊類別給mediator.
: 謝謝

1F：→ ben0209:這篇，開始pureMVC之前只有btns container， 09/01 11:04
2F：→ ben0209:開始 pureMVC 之後，再於 container 的 mediator 中， 09/01 11:04
3F：→ ben0209:動態建立 btn * 20，並註冊對應的 mediator 09/01 11:05
4F：推 hpuser:感謝Ben大提供兩種不同方法的詳細教學，小弟受教了 09/01 11:52
