动态检索当前方法的名称 [英] Dynamically retrieving current method's name

问题描述

我希望能够为项目中的所有类添加当前类名和方法名的跟踪消息.

I'd like to be able to put trace messages of the current class name and method name for all classes in my project.

是否有一种在运行时获取当前方法名称的方法，类似于:

Is there a way to get the current method's name at run time, similar to:

NSLog(@"classname: %@", [self className]);

self是从NSObject派生的类吗?

where self is a class derived out of NSObject?

推荐答案

NSLog(@"method name: %@", NSStringFromSelector(_cmd));

_cmd是所有Objective-C方法都接收到的隐藏参数(如self).它的值是用于调用该方法的选择器.

_cmd is a hidden argument (like self) that all Objective-C methods receive. Its value is the selector that was used to call the method.
