Swift获取应用和设备的信息
1.应用信息
guard let infoDictionary = Bundle.main.infoDictionary else { return }
应用名称
let appDisplayName = infoDictionary["CFBundleDisplayName"] as? String
APP版本号
let appVersion = infoDictionary["CFBundleShortVersionString"] as? String
build版本号
let buildVersion = infoDictionary["CFBundleVersion"] as? String
写成扩展的形式
import Foundation
extension Bundle {
var appDisplayName: String {
if let name = infoDictionary?["CFBundleDisplayName"] as? String {
return name
}
return ""
}
var appVersion: String {
if let version = infoDictionary?["CFBundleShortVersionString"] as? String {
return version
}
return ""
}
var buildVersion: String {
if let version = infoDictionary?["CFBundleVersion"] as? String {
return version
}
return ""
}
}
2.系统信息
系统版本
let systemVersion = UIDevice.current.systemVersion
设备UDID
let identifierNumber = UIDevice.current.identifierForVendor?.uuidString
设备名称
let systemName = UIDevice.current.systemName
设备型号
let model = UIDevice.current.model
设备具体型号（下边列出）
let modelName = UIDevice.current.modelName
设备区域化型号如A1533
let localizedModel = UIDevice.current.localizedModel
获取设备型号，只考虑iPhone的情况
import UIKit
extension UIDevice {
var modelName: String {
var systemInfo = utsname()
uname(&systemInfo)
let machineMirror = Mirror(reflecting: systemInfo.machine)
let identifier = machineMirror.children.reduce("") { identifier, element in
guard let value = element.value as? Int8, value != 0 else { return identifier }
return identifier + String(UnicodeScalar(UInt8(value)))
}
switch identifier {
case "iPhone3,1", "iPhone3,2", "iPhone3,3": return "iPhone 4"
case "iPhone4,1": return "iPhone 4s"
case "iPhone5,1", "iPhone5,2": return "iPhone 5"
case "iPhone5,3", "iPhone5,4": return "iPhone 5c"

case "iPhone9,2": return "iPhone 7 Plus"
case "iPhone9,4": return "iPhone 7 Plus"
case "i386", "x86_64": return "Simulator"
default: return identifier
}
}
}
