swift 获取app版本号及 ios 版本号

func versionCheck(){

letinfoDictionary = NSBundle.mainBundle().infoDictionary

let appdisplayName:AnyObject? = infoDictionary!["CFBundledisplayName"]

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

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

let appversion = majorVersionasString

letiosversion : Nsstring= UIDevice.currentDevice().systemVersion//ios版本

letidentifierNumber = UIDevice.currentDevice().identifierForvendor//设备udid

letsystemName = UIDevice.currentDevice().systemName//设备名称

letmodel = UIDevice.currentDevice().model//设备型号

letlocalizedModel = UIDevice.currentDevice().localizedModel//设备区域化型号如A1533

println(appversion)

}

majorVersion  主程序版本号

minorVersion  build 版本号
