-ObjC链接器标志做什么？ [英] What does the -ObjC linker flag do?

问题描述

简单的问题。
之前可能已经回答了，但是无法得到确切的答案。

Simple question. Might have been answered before but was unable to get a exact answer.

现在，我有一个应用程序与无链接器标志。但是，没有链接器标志，我在将数据添加到视图时会遇到一个非常不同的行为。

Right now, I have an app that works with and without the linker flag. However, without the linker flag, I get a very different behaviour when adding data to a view.

谢谢你们！

推荐答案

此标志使链接器加载库中定义了Objective-C类或类别的每个对象文件。虽然此选项通常会导致更大的可执行文件（由于将额外的目标代码加载到应用程序中），它将允许成功创建包含现有类的类别的有效的Objective-C静态库。

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.
