Xcode 8 显示“您想添加存根吗?"我该如何回答? [英] Xcode 8 says "Do you want to add a stub?" How do I answer?

问题描述

在 Xcode 8 中，如果您声明类(或结构)符合协议，但尚未实现所需的方法(函数?)，Xcode 将给出此消息Type 'ClassName' 不符合协议 'ProtocolName'"，这是真的.

如果您通过单击显示三角形打开错误，您将看到许多带有灰色感叹号图标的项目.每个项目都说协议需要功能......你想添加一个存根吗?"我确实想添加一个存根！我如何告诉它为我添加存根?

解决方案

raphh 的回答是对的，但是 xcode 在这里还是有点问题(至少对我来说)，

如果您在编译点标记转换为感叹号后没有立即选择Fix-it，并且除非您尝试再构建一次，否则您无法使其再次出现.>

在构建之后:点错误图标

当您不立即执行 Fix-it 时:感叹号错误图标

当您有多种方法要实现并且您确实为第一个方法执行了Fix-it 时，您必须重新构建才能再次获得点图标.

In Xcode 8, if you declare that a class (or struct) conforms to a protocol, but haven't implemented the required methods (functions?) Xcode will give this message "Type 'ClassName' does not conform to protocol 'ProtocolName'" which is true.

If you open the error by clicking the disclosure triangle, you will see a number of items with grey exclamation mark icons. Each item says "Protocol requires function ... do you want to add a stub?" I do want to add a stub! How do I tell it to add a stub for me?

解决方案

The answer of raphh is right but xcode is still a little buggy here (at least for me),

If you don't select the Fix-it right after compiling the dot mark transform to exclamation mark and you can't make it appear again unless you try to build one more time.

Right after building : Dot error icon

When you don't do the Fix-it right away : exclamation mark error icon

You have to re-build to get the dot icon again when you have several methods to implement and you did do the Fix-it for the first one.
