duplicate symbols for architecture x86_64

<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>架构 x86_64 的重复符号</p>
<p>这意味着您已经加载了两次相同的函数。由于从其他链接器标志中删除 -ObjC 后问题消失，这意味着此选项导致函数加载两次:</p>
<p>来自技术问答</p>
<blockquote>
<p>This flag causes the linker to load every object file in the library
that defines an Objective-C class or category. While this option will
typically result in a larger executable (due to additional object code
loaded into the application), it will allow the successful creation of
effective Objective-C static libraries that contain categories on
existing classes.</p>
