ios - 快速从字符串中提取值

Question

我有一个如下所示的字符串，我试图将每个部分 (,) 分隔成一个数组。

let stringArr = remainderString.componentsSeparatedByString(",")

0lY6P5Ur90TAQnnnI6wtnb,#29,Projekt-FZK-Haus,Projekt FZK-House create by KHH Forschuungszentrum Karlsruhe,$,$,$,(#67,#229,#275),#42

结果

["0lY6P5Ur90TAQnnnI6wtnb", "#29", "Projekt-FZK-Haus", "Projekt FZK-House create by KHH Forschuungszentrum Karlsruhe", "$", "$", "$", "(#67", "#229", "#275)", "#42"]

如果您注意到，(#67,#229,#275) 部分被分隔为“(#67”、“#229”、“#275)”

我想将(大括号)内的那些值插入到另一个数组中。所以我的问题是，如何找到开头的 ( 和结尾的 ) ？

试试这个:

// Subscripting a String with NSRange. Make dealing with ObjC-classes easier
extension String {
    subscript(range: NSRange) -> String {
        let startIndex = self.startIndex.advancedBy(range.location)
        let endIndex = startIndex.advancedBy(range.length)

        return self[startIndex..<endIndex]
    }
}

let str = "0lY6P5Ur90TAQnnnI6wtnb,#29,Projekt-FZK-Haus,Projekt FZK-House create by KHH Forschuungszentrum Karlsruhe,$,$,$,(#67,#229,#275),#42"
let regex = try! NSRegularExpression(pattern: "\\((#[^\\)]+)\\)", options: [])

if let match = regex.firstMatchInString(str, options: [], range: NSMakeRange(0, str.characters.count)) {
    let substr = str[match.rangeAtIndex(1)]
    let components = substr.componentsSeparatedByString(",")

    print(components)
}
