  • 想知用categories 有咩好處?

  • @sonyvsme 唔會動到個class原本的code. 還可以更清楚表達一個class. 例如. 有個class叫human. 咁當中human做到既method最少都百零二百條啦. 你分categories就可以分成 手做到既method. 腳做到既method. 大腦做到既method. etc, etc咁. 就唔洗二百幾條method分係同一個class當中. 一有bug/error....你就死得xDDD class就可以純粹做blueprint啦. 以後你睇我d教學片, 教到multi-view apps時. 你就明categories幾有用了xDDD
