ios - 如何检测动态库负载
<p><p>有没有办法检测应用在运行时加载了哪些动态库？我查看了 Apple 的 <a href="https://developer.apple.com/library/mac/documentation/DeveloperTools/Conceptual/DynamicLibraries/000-Introduction/Introduction.html#//apple_ref/doc/uid/TP40001908-SW1" rel="noreferrer noopener nofollow">documentation</a>对于动态库，但似乎没有讨论这个。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>获取应用程序在运行时加载的所有库的列表:</p>
<pre><code>// import the dynamic linker API
#import <mach-o/dyld.h>
// After your application finishes launching, maybe in
// -application:didFinishLaunchingWithOptions:
int imageCount = _dyld_image_count();
for (int i=0; i < imageCount; i++) {
NSLog(@"%d - %s", i, _dyld_get_image_name(i));
}
</code></pre>
<p>如果要在每次加载库时调用一个函数，可以使用 <code>_dyld_register_func_for_add_image()</code> 或 <code>_dyld_register_func_for_link_module()</code></p>
<p><strong>重要提示</strong>我只在模拟器中检查过。我认为它应该可以在设备上运行，但我现在还有其他事情需要处理。</p>
