xCode / declaring Static Methods in class
提问by Arcadian
Anyone know how I can declare a static method for an xcode class and then use it in my project?
任何人都知道如何为 xcode 类声明一个静态方法，然后在我的项目中使用它？
I want to create a Common.h class and then do something like this in one of .m file
我想创建一个 Common.h 类，然后在 .m 文件之一中做这样的事情
Common.MyStaticMethod();
Common.MyStaticMethod();
I dont want to have to instantiate and instance of Common
我不想实例化和实例化 Common
回答by taskinoor
You will declare a class level method in Objective-C by using "+" before the method declaration.
您将在 Objective-C 中通过在方法声明前使用“+”来声明类级方法。
// in Common.h + (void)myStaticMethod; // call is from anywhere [Common myStaticMethod]
That is, a "-" before method declaration means instance methods and "+" means class level method which are not related with any particular instance of the class.
也就是说，方法声明前的“-”表示实例方法，“+”表示与类的任何特定实例无关的类级方法。
