身份证号码校验，server端和app端都可以实现。下面实现swift3.0 校验身份证号码是否合法。用swfit 3.0 的String字符串截取
Swift 3的String有三个方法用于做字符串截取
tr.substring(to: String.Index)
str.substring(from: String.Index)
str.substring(with: Range<String.Index>)
用法示例：
var str = "Hello, World"
//这个方法会从字符串的开始截取到to参数指定的索引
str.substring(to: String.Index)
let index = str.index(str.startIndex, offsetBy: 5) //索引为从开始偏移5个位置
str.substring(to: index) // 获取Hello
//这个方法会从from参数指定的索引截取到字符串的末尾
substring(from: String.Index)
let index = str.index(str.startIndex, offsetBy: 7) //索引从开始偏移7个位置
str.substring(from: index) // 输出World
//这个方法是截取指定的字符串范围，范围由Range指定
str.substring(with: Range<String.Index>)
let start = str.index(str.startIndex, offsetBy: 7) //索引从开始偏移7个位置
let end = str.index(str.endIndex, offsetBy: -3) //所有从末尾往回偏移三个位置
let range = start..<end
str.substring(with: range) // 输出Wo
校验身份证号码是否合法：
func validateIDCardNumber(sfz: String) -> Bool {
let value = sfz.trimmingCharacters(in: NSCharacterSet.whitespacesAndNewlines)
var length = 0
if value == "" {
return false
} else {
length = value.characters.count
if length != 15 && length != 18 {
return false
}
}
//省份代码
let arearsArray = ["11","12", "13", "14", "15", "21", "22", "23", "31", "32", "33", "34", "35", "36", "37", "41", "42", "43", "44", "45", "46", "50", "51", "52", "53", "54", "61", "62", "63", "64", "65", "71", "81", "82", "91"]
let valueStart2 = value.substring(to: value.index(value.startIndex, offsetBy: 2))
var arareFlag = false
if arearsArray.contains(valueStart2) {
arareFlag = true
}
if !arareFlag {
return false
}
