您如何将堆栈跟踪打印到 Cocoa 中的控制台/日志? [英] How do you print out a stack trace to the console/log in Cocoa?

问题描述

我想在某些时刻记录调用跟踪，例如失败的断言或未捕获的异常.

解决方案

此代码适用于任何线程:

NSLog(@"%@", NSThread.callStackSymbols);

<块引用>

返回一个包含调用堆栈符号的数组.每个元素都是一个 NSString 对象，其值的格式由 backtrace_symbols() 函数确定.

I'd like to log the call trace during certain points, like failed assertions, or uncaught exceptions.

解决方案

This code works on any thread:

NSLog(@"%@", NSThread.callStackSymbols);

Returns an array containing the call stack symbols. Each element is an NSString object with a value in a format determined by the backtrace_symbols() function.
