ruby 正则表达式中的引号被误解为字符串的开头

我在xcode中有一个macruby项目，我想在其中将字符串中的所有左右引号替换为 ~@@~@@~" 和 "~@@~@@分别是~。我在 rubular.com 上测试了以下代码，它工作正常。

string.gsub!(/\B"/, "~@@~@@~\"")
string.gsub!(/\b"/, "\"~@@~@@~")

但是当我在 xcode 中使用它时，它会将正则表达式中的 " 解释为字符串的开头，并表示我的 gsub 参数数量错误。我尝试过转义引用：

string.gsub!(/\B\"/, "~@@~@@~\"")
string.gsub!(/\b\"/, "\"~@@~@@~")

但这也不起作用。

编辑：我设法让错误消失，似乎是由于其他原因导致的，但我可以处理这个问题。有用。

I have a macruby project in xcode, in which I want to replace all the left and right quotes in a string with ~@@~@@~" and "~@@~@@~, respectively. I tested the following code in rubular.com, and it works correctly.

string.gsub!(/\B"/, "~@@~@@~\"")
string.gsub!(/\b"/, "\"~@@~@@~")

But when I use this in xcode, it interprets the " in the regexp as the beginning of the string, and says I have the wrong numer of arguments for gsub. I tried escaping the quote:

string.gsub!(/\B\"/, "~@@~@@~\"")
string.gsub!(/\b\"/, "\"~@@~@@~")

But that also did not work. Thanks for your help.

EDIT: I managed to get the error to go away, it seems it was due to something else. The highlighting is still off, but I can handle that, since it works.
