推荐答案

您可能有不同的类实现了 item 方法，但返回了不同类型的结果.如果您随后尝试在 id 类型指针上调用 item，则无法知道结果类型应该是什么.

You probably have different classes implementing the method item but returning a different type of result. If you then try to invoke item on an id typed pointer, there's no way to know what the result type is supposed to be.

这就是 XCode 所抱怨的.

That's what XCode is lamenting about.

如何解决在很大程度上取决于您真正想要做什么.可能对方法使用不同的名称是最好的解决方案.

How to solve it depends a lot on what are you really are trying to do. Probably using different names for the methods is the best solution.
