How to escape double quotes in string?
提问by 4thSpace
I'd like double quotes to appear within the following string so it looks like:
我希望双引号出现在以下字符串中，因此它看起来像：
"hi there == "
Here's the code I'm using:
这是我正在使用的代码：
NSMutableString *s = [[NSMutableString alloc] init];
[s appendString:@""""];
[s appendString:@"hi there == ""\n\r"];
Instead I only get:
相反，我只得到：
hi there ==
Any ideas?
有任何想法吗？

[s appendString:@"hi there == \"\n\r"];
\"is what is needed for "- This is standard C formatting.
\"是需要的"- 这是标准的 C 格式。

You have to append a slash (\) before the quote (") to ge the expected output.
您必须在引号 (") 之前附加一个斜杠 (\) 才能获得预期的输出。
[s appendString:@"\"hi there == \"\n\r"];
Output will be "hi there == "
输出将是“你好==”
