[iOS] IBAction標記 - 在Controller標記出View元件的動作

idea...





我是Button按鈕,我有許多行為,
又可以與使用者互動,比如說使用者可以按下我等等的。
我是iOS工程師,
Button按鈕啊,我要知道你什麼時候被按下,
 好執行我要為使用者執行的程式。

iOS工程師,我是Controller,
我又聽到您的需求了,同樣的問題,
Interface Builder以xml的方式保存了Button按鈕,
但我並不知道您要關注Button按鈕的的哪個行為?
因此你必須在我這個Controller上產生一個動作 - IBAction,
讓我Controller與Interface Builder知道,
Button按鈕的某些行為必須對應Controller的哪個方法,
而後即可將你要為使用者的事寫在對應的方法中,
即可為使用者執行想要的程式了!
比如按鈕按下時,讓背景變顏色等等的。
