iOS的Objective C中的属性反射 [英] Property reflection in Objective C for iOS

问题描述

我希望能够在Objective C中的类上使用反射来确定运行时可用的属性。

I would like to be able to use reflection on a classes within Objective C to determine what properties are available at run time.

我为类做了类似的事情现在使用

I do something similar for classes right now using

NSString *str = NSStringFromClass([object class]);  

我想做的是使用这个结果返回课程，看看有哪些属性可用以及这些属性的类型。

What I would like to do is use this result to go back to the class and see what properties are available as well as what type these properties are.

推荐答案

可能会有所帮助：

您可以使用class_copyPropertyList获取类中的属性列表

You can get the list of properties in a class using class_copyPropertyList

objc_property_t * class_copyPropertyList(Class cls, unsigned int *outCount)

然后从每个属性中，您可以使用<$ c $获取属性名称c> property_getName 使用 property_getAttributes 函数的函数和属性属性（如果需要过滤读写属性）。

and then from each property, you can get the property name using property_getName function and the property attributes using the property_getAttributes function (if you need to filter read-write properties).
