How do you print out a stack trace to the console/log in Cocoa?

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

#import <ExceptionHandling/NSExceptionHandler.h>

[[NSExceptionHandler defaultExceptionHandler] setExceptionHandlingMask: NSLogUncaughtExceptionMask | NSLogUncaughtSystemExceptionMask | NSLogUncaughtRuntimeErrorMask]
