Regex 将javascript正则表达式转换为swift nsregularexpression

我是swift编程新手

我在javascript中有一个有效的正则表达式，我在swift中需要相同的功能

str.replace(/\+/g, '-').replace(/\//g, '_').replace(/\=+$/, '');

谢谢

Swift 2.3： Swift 3：

非常感谢，这真的是我的1d

let str = "A+B/C===="

let result = str.stringByReplacingOccurrencesOfString("+", withString: "-")
                .stringByReplacingOccurrencesOfString("/", withString: "_")
                .stringByReplacingOccurrencesOfString("\\=+$", withString: "", options: .RegularExpressionSearch)

print(str)
print(result)

let str = "A+B/C===="

let result = str.replacingOccurrences(of: "+", with: "-")
                .replacingOccurrences(of: "/", with: "_")
                .replacingOccurrences(of: "\\=+$", with: "", options: .regularExpressionSearch)

print(str)
print(result)
