Question

Aipda Karel Sasuit Tubun No.106B，RT.2 / RW.1，Ps。巴鲁，卡拉瓦奇，哥打印度尼西亚万丹15112坦格朗”

我有一个这样的字符串地址，我想获取邮政编码15112，该邮政编码始终位于“印度尼西亚”之前

我是一个初学者，很抱歉，这很简单，因为我在Stackoverflow中找不到它

Answer 1

对不起，我认为这是一个冗长的方法，但这应该可行：

let address = "Aipda Karel Sasuit Tubun No.106B, RT.2/RW.1, Ps. Baru, Karawaci, Kota Tangerang, Banten 15112, Indonesia"
let keyword = "Indonesia"

let components: [String] = address.split(separator: " ").map({ String($0).replacingOccurrences(of: ",", with: "") })
var postCode = components.first ?? ""

for comp in components {
    if comp == keyword {
        break
    }
    postCode = comp
}

print(postCode)

Answer 2

let address = "Aipda Karel Sasuit Tubun No.106B, RT.2/RW.1, Ps. Baru, Karawaci, Kota Tangerang, Banten 15112, Indonesia"

func postcode(from address: String, for area: String) -> String? {
    let array = address.replacingOccurrences(of: ",", with: "").components(separatedBy: " ")
    if let index = array.lastIndex(where: { $0.contains(area) }) {
        return array[index - 1]
    }
    return nil
}

postcode(from: address, for: "Indonesia")

Answer 3

您可以使用正则表达式：

let str = "Aipda Karel Sasuit Tubun No.106B, RT.2/RW.1, Ps. Baru, Karawaci, Kota Tangerang, Banten 15112, Indonesia"
let range = NSRange(location: 0, length: str.utf16.count)
let regex = try! NSRegularExpression(pattern: "[0-9]+(?=, Indonesia)")

if let match = regex.firstMatch(in: str, range: range) {
    let subStr = String(str[Range(match.range, in: str)!])
    print(subStr) //15112
}
