對單例的理解
在objective c中要實現乙個單例類，至少需要做以下四個步驟 1 為單例物件實現乙個靜態例項，並初始化，然後設定為nil static student st nil 2 實現乙個例項構造方法檢查上面宣告的靜態例項是否為nil，如果為nil就新建並返回乙個本類的例項，student sharei...

對單例的認知
最近看到了 單例 這塊，簡單記錄下 單例就是該類只能返回乙個例項。單例所具備的特點 1.私有化的建構函式 2.私有的靜態的全域性變數 3.公有的靜態的方法 單例分為 懶漢式 餓漢式和雙層鎖式 餓漢式 先初始化物件 single類一進記憶體，就已經建立好了物件 public class singlet...
