swift 获取app版本号及 ios 版本号

func versionCheck(){

let infoDictionary = NSBundle.mainBundle().infoDictionary

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   //设备 udid

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

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

let localizedModel = 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
