I am using Instruments to debug my allocation in my iOS app and was wondering if there was a way to add flags to the trace while the code is running. For example, I'd like a flag that says "user tapped on button X" to be added automatically once the user tapped on that button.
我正在使用工具调试iOS应用程序中的分配，我想知道是否有一种方法可以在代码运行时向跟踪添加标记。例如，我想要一个标志，上面写着“用户点击按钮X”，一旦用户点击那个按钮，就会自动添加。
From what it seems from Apple docs, you can only add those flags 'after the fact'.
从苹果文档来看，你只能在“事后”添加这些标志。

Basically, you can add a trace onto a particular method that you know you want to trace in advance by swizzling out the real implementation for your custom implementation which logs a tracing statement before calling the real implementation (in this case, you can override -[UIButton endTrackingWithTouch: withEvent:]).
基本上，您可以在特定的方法上添加一个跟踪，您知道您想要预先跟踪，在调用真正的实现之前(在本例中，您可以重写-[UIButton endTrackingWithTouch: withEvent:])，在您的自定义实现中进行真正的实现。
