ios - 每个堆栈跟踪行末尾的数字是什么意思？
<p><p>我正在检查一些 Xcode 崩溃日志，我想知道每行末尾的数字意味着:</p>

<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>它们是机器码偏移量</p>
<p>例如在这张图片中，</p>
<ul>
<li><code>libsystem_kernel.dylib mach_msg</code>的机器码从地址<code>0x18474f054</code>开始。</li>
<li><code>libsystem_kernel.dylib mach_msg + 68</code>，如你所见，这里是调用<code>mach_msg_trap</code>的地方，<code>mach_msg_trap</code>的地址是<code>0x18474f21c</code>,</li>
<li><code>libsystem_kernel.dylib mach_msg + 72</code>是断点停止的地方，等于<code>0x18474f054 + 0x72</code></li>
</ul>
