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.
