iOS开发swift -- 获取版本号、app信息、设备信息

代码示例

        //获取当前版本号
        let currentVersion = Bundle.main.infoDictionary!["CFBundleShortVersionString"] as! String
        //获取历史版本号
        let sandboxVersion = UserDefaults.standard.object(forKey: "CFBundleShortVersionString") as? String ?? ""
        
        //版本比较
        if currentVersion.compare(sandboxVersion) == ComparisonResult.orderedDescending {
            //发现新版本 存储当前的版本到沙盒
            UserDefaults.standard.set(currentVersion, forKey: "CFBundleShortVersionString")
        }

        //获取app信息
        let infoDictionary : Dictionary = Bundle.main.infoDictionary!
        //程序名称
        let appDisplayName : String = infoDictionary["CFBundleDisplayName"] as! String
        //版本号
        let majorVersion :String = infoDictionary ["CFBundleShortVersionString"] as! String
        //build号
        let minorVersion :String = infoDictionary ["CFBundleVersion"] as! String
        
        //获取设备信息
        //ios版本
        let iosVersion : NSString = UIDevice.current.systemVersion as NSString
        //设备udid
        let identifierNumber  = UIDevice.current.identifierForVendor
        //设备名称
        let deviceName : String = UIDevice.current.name
        //系统名称
        let systemName : String = UIDevice.current.systemName
        //设备型号
        let model = UIDevice.current.model
        //设备区域化型号如A1533
        let localizedModel = UIDevice.current.localizedModel
