.
I have a String like "75003 Paris, France"
or "Syracuse, NY 13205, USA"
.
我想使用相同的代码从这些字符串中删除所有这些数字.
I want to use the same code to remove all those numbers out of those Strings.
预期的输出是法国巴黎"
或 美国纽约州锡拉丘兹"
.
我怎样才能做到这一点?
How can I achieve that?
你可以用 NSCharacterSet
var str = "75003 Paris, France"
var stringWithoutDigit = (str.componentsSeparatedByCharactersInSet(NSCharacterSet.decimalDigitCharacterSet()) as NSArray).componentsJoinedByString("")
println(stringWithoutDigit)
输出:
Paris, France

Swift 4.x:
let str = "75003 Paris, France"
let stringWithoutDigit = (str.components(separatedBy: CharacterSet.decimalDigits)).joined(separator: "")
print(stringWithoutDigit)
