X code给出3程序处理流浪'\\ 342'语法错误 [英] Xcode gives 3 syntax errors dealing with Stray '\342' in program

问题描述

我的工作与第X code在Objective-C一个简单的项目，我得到一些流浪/对以下行code的错误：

I am working on a simple project in Objective-C in Xcode and I'm getting some stray/ errors about the following line of code:

if(celsius < −273.15) {
        NSLog(@"It is impossible to convert temperatures less than −273.15 degrees Celsius, because this is absolute zero, the coldest possible temperature.");
    }

它实际上是只有第一线，但我想给一些背景。

It's actually only about the first line, but I wanted to give some context.

有什么建议？

我在这里看着它在左右，但其他人的错误一直没有这样简单code像我这样的，虽然看起来他们有某些标点错误编码的一个共同的问题，也许？

I've looked it up here on SO, but everyone else's error hasn't had such simple code like mine, although it appears they have a common problem of having the wrong encoding for certain punctuation, perhaps?

这一定是只是我的if语句语法的一些这个..

It's got to be just some syntax this on my if statement..

更新：

看起来好像它也显示2其他杂散错误：

It looks as though it also displays 2 other stray errors:

流浪'\\ 210'
流浪'\\ 222

Stray '\210' Stray '\222'

推荐答案

！ - = -

− != -

您减号，是不是减号。
