如何将堆栈跟踪打印到Cocoa中的控制台/日志？

本文翻译自：[How do you print out a stack trace to the console/log in Cocoa?][How do you print out a stack trace to the console_log in Cocoa]

我想在某些点记录调用跟踪，例如失败的断言或未捕获的异常。

*n13's answer didn't quite work - I modified it slightly to come up with this* **n13的答案并不是很有效 - 我稍微修改了它以得出这个**

#import <UIKit/UIKit.h>
    
    #import "AppDelegate.h"
    
    int main(int argc, char *argv[])
    {
        @autoreleasepool {
            int retval;
            @try{
                retval = UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
            }
            @catch (NSException *exception)
            {
                NSLog(@"Gosh!!! %@", [exception callStackSymbols]);
                @throw;
            }
            return retval;
        }
    }

*[This][] pretty much tells you what to do.* **[这][This]几乎告诉你该怎么做。**

*Essentially you need to set up the applications exception handling to log, something like:* **基本上，您需要设置应用程序异常处理以进行记录，例如：**

#import <ExceptionHandling/NSExceptionHandler.h>
    
    [[NSExceptionHandler defaultExceptionHandler] 
                      setExceptionHandlingMask: NSLogUncaughtExceptionMask | 
                                                NSLogUncaughtSystemExceptionMask | 
                                                NSLogUncaughtRuntimeErrorMask]

*For exceptions, you can use the NSStackTraceKey member of the exception's userInfo dictionary to do this.* **对于异常，您可以使用异常的userInfo字典的NSStackTraceKey成员来执行此操作。** *See [Controlling a Program's Response to Exceptions][Controlling a Program_s Response to Exceptions] on Apple's website.* **请参阅Apple网站上的[控制程序对例外的响应][Controlling a Program_s Response to Exceptions] 。**

### \#5楼 ###

*Cocoa already logs the stack trace on uncaught exceptions to the console although they're just raw memory addresses.* **Cocoa已经将未捕获的异常的堆栈跟踪记录到控制台，尽管它们只是原始内存地址。** *If you want symbolic information in the console there's some [sample code][This] from Apple.* **如果您想在控制台中获得符号信息，那么Apple会提供一些[示例代码][This] 。**

*If you want to generate a stack trace at an arbitrary point in your code (and you're on Leopard), see the backtrace man page.* **如果要在代码中的任意点生成堆栈跟踪（并且您在Leopard上），请参阅backtrace手册页。** *Before Leopard, you actually had to dig through the call stack itself.* **在Leopard之前，你实际上不得不深入挖掘调用堆栈本身。**

NSLog(@"%@",[NSThread callStackSymbols]);

此代码适用于任何线程。
