实例和方法的命名约定

Question

What is the standard way to name an instance:

NSString* myString;

or

NSString* my_string;

Similarly, what is the standard way to name a method:

(void) getMyName;

or

(void) get_my_name;

Answer 1

camelCase is the standard. Have a look at Apple's Cocoa coding guidelines .

Answer 2

Also getter methods do NOT have the get keyword in it. So getMyName should just be myName .

Answer 3

虽然我还建议使用jtbandes提供的链接，但本文可能会帮助您理解以及如何编写。 可可指南具有很好的定义以及可以快速浏览的漂亮示例。

Answer 4

It depends on the guidelines (1) applied in your product (2) suggested by the language.

Many guidelines for C++, Java and other languages suggest camelCase , like getMyName() , while python suggest lower_case_with_underscores , like get_my_name() , see PEP 8 .
