如何在 Objective-C 中记录每个被调用的类方法的名称? [英] How can I log names of each called class method in Objective-C?

问题描述

当我想查看对象方法调用的顺序时，我必须像这样记录我实现的每个方法.

When I want to see the order of the object method calls, I have to put logs each method I implemented like this.

- (void)updateTime:(float)time
{
  NSLog(@"%s", __PRETTY_FUNCTION__);

所以我不得不把这段代码放在类的每个方法中，每次调试一个类的时候插入和删除这么多日志函数调用很无聊.

Hence I have to put this code in every method on the class, and it's very boring to insert and delete so many log function calls every time I am debugging a class.

那么如何在每个方法调用的类中触发 NSLog(@"%s", __PRETTY_FUNCTION__);​​?

So how can I trigger NSLog(@"%s", __PRETTY_FUNCTION__); in a class on each method call?

我最终得到了这段代码.并且在其他任何地方都没有得到答复.

I ended up with this code. And was not answered anywhere else.

- (BOOL)respondsToSelector:(SEL)aSelector {
    if(aSelector){
        NSLog(@"%@", NSStringFromSelector(aSelector));
    }
    return [super respondsToSelector:aSelector];
}

推荐答案

您可以使用 NSObjCMessageLoggingEnabled=YES 运行您的可执行文件.您可以在 Xcode Schemes 中的 Run 下的 Argument Variables 下进行设置.

You can run your executable with NSObjCMessageLoggingEnabled=YES. You can set this in Xcode Schemes, under Argument Variables under Run.

你最终会得到类似的输出

You end up with output like

    + NSObject NSObject initialize
    + NSNotificationCenter NSObject initialize
    + NSNotificationCenter NSNotificationCenter defaultCenter
