Swift获取设备信息

1,获取App 相关信息:

// OC
NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];
NSString *appVersion = [infoDic objectForKey:@"CFBundleShortVersionString"]; 
NSString *appBuildVersion = [infoDic objectForKey:@"CFBundleVersion"]; 
NSString *appName = [infoDic objectForKey:@"CFBundleDisplayName"]; 
// SWIFT
let infoDic = NSBundle.mainBundle().infoDictionary
let appVersion = infoDic?["CFBundleShortVersionString"] // 获取App的版本
let appBuildVersion = infoDic?["CFBundleVersion"] // 获取App的build版本
let appName = infoDic?["CFBundleDisplayName"] // 获取App的名称

2, 获取设备信息:

// OC
NSString *deviceName = [[UIDevice currentDevice] name]; 
NSString *sysVersion = [[UIDevice currentDevice] systemName]; 
NSString *sysVersion = [[UIDevice currentDevice] systemVersion]; 
NSString *deviceUUID = [[[UIDevice currentDevice] identifierForVendor] UUIDString]; 
NSString *deviceModel = [[UIDevice currentDevice] model]; 
// SWIFT
let deviceName = UIDevice.currentDevice().name  //获取设备名称 例如：某某的手机
let sysName = UIDevice.currentDevice().systemName //获取系统名称 例如：iPhone OS
let sysVersion = UIDevice.currentDevice().systemVersion //获取系统版本 例如：9.2
let deviceUUID = UIDevice.currentDevice().identifierForVendor?.UUIDString  //获取设备唯一标识符 例如：11AEAE29-DF1F-4681-9A8A-AF72335FDE02
let deviceModel = UIDevice.currentDevice().model //获取设备的型号 例如：iPhone

3, 获取设备型号:

extension UIDevice {
    var modelName: String {
        var systemInfo = utsname()
        uname(&systemInfo)
        let machineMirror = Mirror(reflecting: systemInfo.machine)
        let identifier = machineMirror.children.reduce("") { identifier, element in
            guard let value = element.value as? Int8, value != 0 else { return identifier }
            return identifier + String(UnicodeScalar(UInt8(value)))
        }
        switch identifier {
        case "iPod5,1":                                 return "iPod Touch 5"

        case "iPhone7,1":                               return "iPhone 6 Plus"
        case "iPhone8,1":                               return "iPhone 6s"
        case "iPhone8,2":                               return "iPhone 6s Plus"

        case "iPad2,1", "iPad2,2", "iPad2,3", "iPad2,4":return "iPad 2"
        case "iPad3,1", "iPad3,2", "iPad3,3":           return "iPad 3"
        case "iPad3,4", "iPad3,5", "iPad3,6":           return "iPad 4"
        case "iPad4,1", "iPad4,2", "iPad4,3":           return "iPad Air"
        case "iPad5,3", "iPad5,4":                      return "iPad Air 2"
        case "iPad2,5", "iPad2,6", "iPad2,7":           return "iPad Mini"
        case "iPad4,4", "iPad4,5", "iPad4,6":           return "iPad Mini 2"
        case "iPad4,7", "iPad4,8", "iPad4,9":           return "iPad Mini 3"
        case "iPad5,1", "iPad5,2":                      return "iPad Mini 4"
        case "iPad6,7", "iPad6,8":                      return "iPad Pro"
        case "AppleTV5,3":                              return "Apple TV"
        case "i386", "x86_64":                          return "Simulator"
        default:                                        return identifier
