嗨,我的值是
块引用 1 1:0.0644343 1 1:0.0309334 1 1:0.0261616 块引用
我希望按空格分隔值,但在某些字符之后得到这样的结果..是否有任何可能的解决方案。我知道我们可以在正则表达式中做到

我认为正则表达式是完美的工具:
var str = "Blockquote 1 1:0.0644343 1 1:0.0309334 1 1:0.0261616 Blockquote"
let regex = try! NSRegularExpression(pattern: "(\\d \\d:[\\.0-9]+)", options: [])
let matches = regex.matchesInString(str, options: [], range: NSMakeRange(0, str.characters.count))
for m in matches.reverse() {
let range = m.rangeAtIndex(1)
let startIndex = str.startIndex.advancedBy(range.location)
let endindex = startIndex.advancedBy(range.length)
let value = str[startIndex..<endindex]
str.replaceRange(startIndex..<endindex, with: "\"\(str[startIndex..<endindex])\"")
}
print(str)
