在NSClassFromString()返回的类上调用类方法

Question

NSClassFromString(aClassName)返回名为aClassName的类的类对象.大.

现在如何在该类对象上调用类方法？对于

  Class moduleClass = NSClassFromString(aClassName);

Xcode不允许我打电话

  AppModule* appModuleClass = moduleClass;
  [appModuleClass classMethod]     // actually that's an object instance...

要么

  [((AppModule)moduleClass) classMethod];     // C-style cast not allowed

我在这里错过了什么？谢谢.

要调用类方法,请执行以下操作:

[NSClassFromString(aClassName) performSelector:@selector(classMethod)];

也许这可行:

objc_msgSend(NSClassFromString(aClassName), @selector(classMethod));
