        let appDisplayName: AnyObject? = infoDictionary!["CFBundleDisplayName"]

        let majorVersion : AnyObject? = infoDictionary! ["CFBundleShortVersionString"]

        let minorVersion : AnyObject? = infoDictionary! ["CFBundleVersion"]

        let appversion = majorVersion as String

        let iosversion : NSString = UIDevice.currentDevice().systemVersion   //ios 版本

        let identifierNumber = UIDevice.currentDevice().identifierForVendor   //設備 udid

        let systemName = UIDevice.currentDevice().systemName   //設備名稱

        let model = UIDevice.currentDevice().model   //設備型號

        let localizedModel = UIDevice.currentDevice().localizedModel   //設備區域化型號 如 A1533

 

        

        println(appversion)
