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
