ios - 如何使用 NSSetUncaughtExceptionHandler 获取未捕获异常的类、方法和行号
<p><p>我使用 <code>NSSetUncaughtExceptionHandler(&HandleExceptions);</code> 来处理方法中未捕获的异常</p>
<pre><code>void HandleExceptions(NSException *exception)
{
}
</code></pre>
<p>我想打印发生异常的类、方法和行号有什么解决办法吗？？</p>
<p>我正在跟踪堆栈跟踪</p>
<pre><code>0 appName 0x00000001000b6a20 HandleExceptions + 584

<p><p>处理程序获取 <a href="https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSException_Class/index.html#//apple_ref/occ/instp/NSException/callStackSymbols" rel="noreferrer noopener nofollow"><code>NSException</code></a> 的实例.有两种方法:<code>-callStackSymbols</code>和<code>-callStackReturnAddresses</code>。</p>
<p><code>-callStackSymbols</code>如果可能的话，给你回溯字符串。</p>
<p>看起来像这样:</p>
<pre><code>0 TestArrayCopy 0x0000000100000dfe - + 46
1 TestArrayCopy 0x0000000100000e97 main + 87
2 libdyld.dylib 0x00007fff940be5fd start + 1
3 ??? 0x0000000000000001 0x0 + 1
</code></pre>
<p>如你所见，有一个关于方法所有者的信息(<code>-</code> 用于实例方法)、类名(<code>MyClass</code>)和方法名(<code>方法</code>)。</p></p>
