Swift4.0_获取设备以及APP本地和APPStore的信息

1-获取APP的部分信息

let localInfoDic = Bundle.main.infoDictionary
print(localInfoDic!["CFBundleName"] ?? String()) //程序名称 eg:ZZDS
print(localInfoDic!["CFBundleShortVersionString"] ?? String())//主程序版本号 eg:1.0.1
print(localInfoDic? ["CFBundleVersion"] ?? String())//App Build版本号（内部标示） eg:2
print(localInfoDic!["DTPlatformName"]  ?? String())//eg: iphoneos
print(UIDevice.current.systemVersion as NSString) //设备的系统版本 eg:11.1

2-获取设备的部分信息

print(UIDevice.current.identifierForVendor ?? String())//设备udid
print(UIDevice.current.identifierForVendor?.uuid ?? String()) //设备UUID
print(UIDevice.current.systemName) //设备系统名称 eg: iPhone OS
print(UIDevice.current.name) //设备名称 eg: 我i东方
print(UIDevice.current.model)  //设备型号 eg:iPhone
print(UIDevice.current.localizedModel) //设备区域化型号 eg:iPhone
print(UIDevice.current.modelName)  //设备型号名称 eg: iPhone 6s(这个需要增加下面对UIDevice的扩展)
//MARK: - UIDevice扩展
 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 "iPod1,1":  return "iPod Touch 1"
        case "iPod2,1":  return "iPod Touch 2"
        case "iPod3,1":  return "iPod Touch 3"
        case "iPod4,1":  return "iPod Touch 4"
        case "iPod5,1":  return "iPod Touch (5 Gen)"
        case "iPod7,1":   return "iPod Touch 6"
            
        case "iPhone3,1", "iPhone3,2", "iPhone3,3":  return "iPhone 4"
        case "iPhone4,1":  return "iPhone 4s"
        case "iPhone5,1":   return "iPhone 5"
        case  "iPhone5,2":  return "iPhone 5 (GSM+CDMA)"
        case "iPhone5,3":  return "iPhone 5c (GSM)"
        case "iPhone5,4":  return "iPhone 5c (GSM+CDMA)"
        case "iPhone6,1":  return "iPhone 5s (GSM)"
        case "iPhone6,2":  return "iPhone 5s (GSM+CDMA)"
        case "iPhone7,2":  return "iPhone 6"
        case "iPhone7,1":  return "iPhone 6 Plus"
        case "iPhone8,1":  return "iPhone 6s"
        case "iPhone8,2":  return "iPhone 6s Plus"
        case "iPhone8,4":  return "iPhone SE"
        case "iPhone9,1":   return "国行、日版、港行iPhone 7"
        case "iPhone9,2":  return "港行、国行iPhone 7 Plus"
        case "iPhone9,3":  return "美版、台版iPhone 7"
        case "iPhone9,4":  return "美版、台版iPhone 7 Plus"
        case "iPhone10,1","iPhone10,4":   return "iPhone 8"
        case "iPhone10,2","iPhone10,5":   return "iPhone 8 Plus"
        case "iPhone10,3","iPhone10,6":   return "iPhone X"
            
        case "iPad1,1":   return "iPad"
        case "iPad1,2":   return "iPad 3G"
        case "iPad2,1", "iPad2,2", "iPad2,3", "iPad2,4":   return "iPad 2"
        case "iPad2,5", "iPad2,6", "iPad2,7":  return "iPad Mini"
        case "iPad3,1", "iPad3,2", "iPad3,3":  return "iPad 3"
        case "iPad3,4", "iPad3,5", "iPad3,6":   return "iPad 4"
        case "iPad4,1", "iPad4,2", "iPad4,3":   return "iPad Air"
        case "iPad4,4", "iPad4,5", "iPad4,6":  return "iPad Mini 2"
        case "iPad4,7", "iPad4,8", "iPad4,9":  return "iPad Mini 3"
        case "iPad5,1", "iPad5,2":  return "iPad Mini 4"
        case "iPad5,3", "iPad5,4":   return "iPad Air 2"
        case "iPad6,3", "iPad6,4":  return "iPad Pro 9.7"
        case "iPad6,7", "iPad6,8":  return "iPad Pro 12.9"
        case "AppleTV2,1":  return "Apple TV 2"
        case "AppleTV3,1","AppleTV3,2":  return "Apple TV 3"
        case "AppleTV5,3":   return "Apple TV 4"
        case "i386", "x86_64":   return "Simulator"
        default:  return identifier
        }
    }
}

3-获取APP在APPStore 里面的版本号并检测更新

（使用到了第三方数据请求的库Alamofire，级别同OC的AFNetWorking）

    class func getLocalAPPVersionAndCheckUpdateAPP(appID:String){
        
        let localInfoDic = Bundle.main.infoDictionary
        var currentVersion :String = localInfoDic!["CFBundleShortVersionString"] as! String
        UserDefaultSet(object: currentVersion , key: "local_Vsersion")
        print("本地的版本号：\(currentVersion)")
        
        Alamofire.request("https://itunes.apple.com/cn/lookup?id=\(appID)", method: .post, parameters:nil).responseJSON { (returnResult) in
            
            guard let resultDic = returnResult.result.value as? [String:Any] else{
                print("无网络服务")
                return
            }
            let resultArray :NSArray = resultDic["results"] as! NSArray
            guard let versionDic = resultArray.lastObject as? [String:Any] else{
                print("使用的 id 不对")
                return
            }
            var appStoreVersion :String = versionDic["version"] as!String
            
            appStoreVersion = appStoreVersion.replacingOccurrences(of: ".", with: "")
            if appStoreVersion.count == 1 {
                appStoreVersion.append("00")
            }else if appStoreVersion.count == 2 {
                appStoreVersion.append("0")
            }
            currentVersion = currentVersion.replacingOccurrences(of: ".", with: "")
            if currentVersion.count == 1 {
                currentVersion.append("00")
            }else if appStoreVersion.count == 2 {
                appStoreVersion.append("0")
            }
            
            if Float(currentVersion)! < Float(appStoreVersion)! {
                print("更新版本")
                let url = NSURL.init(string: "https://itunes.apple.com/us/app/id\(appID)?ls=1&mt=8")
                UIApplication.shared.openURL(url! as URL)
            }
            print(versionDic["version"] ?? String() )

      }
    }
