我有一个可以使用和不使用链接器标志的应用程序。但是，如果没有链接器标志，我在向 View 中添加数据时会得到非常不同的行为。

最佳答案

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.
