传递带有Objective-C（Cocoa）事件（performSelector）的C ++对象
问题描述：
如何使用performSelector方法传递C ++对象？这个方法只允许你传递objc_object *对象，我不能投射它们。我可以构建一个包装器，但我不知道所有C ++对象的整体超类，所以我不知道我如何能够构建一个通用包装器（我不想在包装器中的对象的具体知识）。
How to pass a C++ object with the performSelector method? This method only allows you to pass 'objc_object*' objects, I can't cast them. I could build a wrapper, but I don't know the overall superclass for all C++ objects, so I don't know how I could build a generic wrapper (I don't want specific knowledge about the object in the wrapper)..
任何提示？
答
尝试使用+ [NSValue valueWithPointer ：]
Try just using +[NSValue valueWithPointer:].
