所以我试图弄清楚如何根据 ip 验证掩码 ip(在范围内? 我似乎找不到像在 java 中那样在 swift 中找到工具:
如何检测 IP 是否在网络中?
let ip = "192.168.2.0"
let net = "192.168.1.0"
let pref = 24
func convertIpToInt(_ ipAddress: String) -> Int? {
var result = 0.0
let ipAddressArray = ipAddress.components(separatedBy: ".").compactMap {
Double($0) }
guard ipAddressArray.count == 4 else { return nil }
for (index, element) in ipAddressArray.enumerated() {
result += element * pow(256, Double(3 - index))
}
return Int(result) > 0 ? Int(result) : nil
}
let ipInt = convertIpToInt(ip)
let netInt = convertIpToInt(net)
let brkstInt = netInt! + Int(pow(2, Double(32-pref))) - 1
print(ipInt! >= netInt! && ipInt! <= brkstInt) // false
