如何使结构符合Equatable"协议?

How do I make a structure conform to protocol "Equatable"?

我使用的是 Xcode 7.3.1

I'm using Xcode 7.3.1

struct MyStruct { var id: Int var value: String init(id: Int, value: String) { self.id = id self.value = value } var description: String { return "blablabla" } }

当我使用MyStruct"时，Xcode 显示错误:

When I use "MyStruct", Xcode shows the error:

MyStruct 不符合Equatable"协议

MyStruct does not conform to protocol "Equatable"

您有没有让 MyStruct 符合协议的想法?

Do you have an idea to make MyStruct conform to protocol?

推荐答案

好的，经过大量搜索，它起作用了...

OK, after lots of searching, it's working...

struct MyStruct { var id: Int var value: String init(id: Int, value: String) { self.id = id self.value = value } var description: String { return "blablabla" } } extension MyStruct: Equatable {} func ==(lhs: MyStruct, rhs: MyStruct) -> Bool { let areEqual = lhs.id == rhs.id && lhs.value == rhs.value return areEqual }

我的 Struct 在一个类中，所以它不起作用..我把这个 Struct 从我的类中移出，现在它很好:)

My Struct was in a class, so it didn't work.. I moved this Struct out of my class and now it's good :)
