如果抛出未处理的NSException,则堆栈跟踪的部分如下所示:
Last Exception Backtrace:
0 CoreFoundation 0x32bd688f __exceptionPreprocess + 163
1 libobjc.A.dylib 0x34b7b259 objc_exception_throw + 33
2 CoreFoundation 0x32bd65c5 -[NSException init] + 1
3 Foundation 0x37296bd7 -[NSObject(NSKeyValueCoding) valueForUndefinedKey:] + 263
...
但是如果抛出std :: exception,我只得到这个:
Thread 0 Crashed:
0 libsystem_kernel.dylib 0x34f2632c __pthread_kill + 8
1 libsystem_c.dylib 0x31e4c208 pthread_kill + 48
