App-快速搭建項(xiàng)目框架-AppDelegate入口

AppDelegate組件化

AppDelegate瘦身

AppDelegate是App的入口，對(duì)于開(kāi)發(fā)耦合性來(lái)說(shuō)憔维，AppDelegate除了負(fù)責(zé)應(yīng)用生命周期之外淹辞，盡量不要有大量的代碼地沮。
但是在iOS 實(shí)際開(kāi)發(fā)過(guò)程中攀例，很多人習(xí)慣將全局變量定義在 AppDelegate 中，會(huì)導(dǎo)入比如推送皿曲、統(tǒng)計(jì)唱逢、分享、三方登陸屋休、地圖等組件坞古，但如此這般，AppDelegate就變得更加臃腫劫樟。在大型項(xiàng)目中痪枫，想要解除耦合和模塊化時(shí)，都不利于AppDelegate的維護(hù)叠艳。
將很多全局變量放在AppDelegate上奶陈，將AppDelegate作為一個(gè)依賴(lài)中心點(diǎn)，雖然很多模塊可以訪問(wèn)全局變量附较，但會(huì)產(chǎn)生相互依賴(lài)吃粒，不利于模塊化開(kāi)發(fā)；
不同的模塊拒课，會(huì)根據(jù)需要在AppDelegate的不同生命周期方法中徐勃，調(diào)用各種方法。比如在程序啟動(dòng)時(shí)在application:didFinishLaunchingWithOptions:內(nèi)注冊(cè)一個(gè)初始化方法早像；
