object-c get开头的函数名是什么意思

在Cocoa编程中,'get'方法名表示该方法通过传入的参数返回一个值,相当于C语言中的输出参数。以buffer range为例,展示了如何在Cocoa环境中使用输出参数。

get 在 Cocoa 中有特殊含义,The word “get” has a special meaning in Cocoa: in a Cocoa method name, it means the method returns a value via a pointer that you pass in as a parameter.

翻译过来是什么意思:就是C语言中的输出参数了。

例如:

buffer range:(NSRange)aRange

buffer就是一个输出参数。
