很久没有写过博客了，由于中间工做比较忙，而后有些我的事情因此耽误了。可是以前写的博客还一直有人来问一些问题，有些以前写的已经比较久了，有些须要实时更新的也没来得及更新，发现会跟一些童鞋形成困惑，因此之后也但愿能及时更新和写一些新的内容。

我以前博客的地址：一毛的博客，也是主要介绍iOS开发的，之后都在简书更新吧。但愿你们能继续支持。
iOS开发过程当中，有时候为了更好的用户体验或者为了bug跟踪，可能会须要获取用户的应用信息、系统信息、设备信息。这些信息的获取能够根据不一样的设备或者App、系统版原本提供不一样的功能或更好的用户体验，或者让开发者能更好的分析用户的问题缘由。

你说不要啰嗦了：Talk is cheap, show me the code！

好的，code来了：

获取设备名称

OC代码
NSString *deviceName = [[UIDevice currentDevice] name];

Swift代码
let deviceName = UIDevice.currentDevice().name

获取系统版本号

OC代码
NSString *sysVersion = [[UIDevice currentDevice] systemVersion];

Swift代码
let sysVersion = UIDevice.currentDevice().systemVersion

获取设备惟一标识符

OC代码
NSString *deviceUUID = [[[UIDevice currentDevice] identifierForVendor] UUIDString];

Swift代码
let deviceUUID = UIDevice.currentDevice().identifierForVendor?.UUIDString

获取设备的型号

OC代码
NSString *deviceModel = [[UIDevice currentDevice] model];

Swift代码
let deviceModel = UIDevice.currentDevice().model

获取App相关的信息

OC代码

NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];

// 获取App的版本号
NSString *appVersion = [infoDic objectForKey:@"CFBundleShortVersionString"];

// 获取App的build版本
NSString *appBuildVersion = [infoDic objectForKey:@"CFBundleVersion"];

// 获取App的名称
NSString *appName = [infoDic objectForKey:@"CFBundleDisplayName"];
Swift代码

let infoDic = NSBundle.mainBundle().infoDictionary

// 获取App的版本号
let appVersion = infoDic?["CFBundleShortVersionString"]

// 获取App的build版本
let appBuildVersion = infoDic?["CFBundleVersion"]

// 获取App的名称
let appName = infoDic?["CFBundleDisplayName"]
有些人可能会说了：“裤子都脱了，你就给我看这个！看你以前写的博客还能看点儿干货，今天第一篇就写着么个玩意儿？尤为是获取设备型号那个，获取出来一个iPhone，你肯定不是在逗我吧？”

看官别急，其实此次最主要的就是来分享获取设备型号的方法的，由于我看国内还不多有Swift写的一些东西，也不知道是否是由于我没有找到，就想本身写出来给你们分享，顺便作个笔记。

你会说：获取设备型号比较麻烦，又用的是C语言的一些东西，比较麻烦，并且还得记住全部设备版本号例如：iPhone8,2，实在是记不住啊。固然不用记住，用的时候拷过来就好了，由于我也记不住😄

iOS获取具体设备型号
OC代码获取iOS设备型号：
// 须要#import <sys/utsname.h>

• (NSString)deviceModelName
  {
  struct utsname systemInfo;
  uname(&systemInfo);
  NSString deviceModel = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];

  //iPhone 系列
  if ([deviceModel isEqualToString:@"iPhone1,1"]) return @"iPhone 1G";
  if ([deviceModel isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
  if ([deviceModel isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS";
  if ([deviceModel isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
  if ([deviceModel isEqualToString:@"iPhone3,2"]) return @"Verizon iPhone 4";
  if ([deviceModel isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
  if ([deviceModel isEqualToString:@"iPhone5,1"]) return @"iPhone 5";
  if ([deviceModel isEqualToString:@"iPhone5,2"]) return @"iPhone 5";
  if ([deviceModel isEqualToString:@"iPhone5,3"]) return @"iPhone 5C";
  if ([deviceModel isEqualToString:@"iPhone5,4"]) return @"iPhone 5C";
  if ([deviceModel isEqualToString:@"iPhone6,1"]) return @"iPhone 5S";
  if ([deviceModel isEqualToString:@"iPhone6,2"]) return @"iPhone 5S";
  if ([deviceModel isEqualToString:@"iPhone7,1"]) return @"iPhone 6 Plus";
  if ([deviceModel isEqualToString:@"iPhone7,2"]) return @"iPhone 6";
  if ([deviceModel isEqualToString:@"iPhone8,1"]) return @"iPhone 6s";
  if ([deviceModel isEqualToString:@"iPhone8,2"]) return @"iPhone 6s Plus";

  //iPod 系列
  if ([deviceModel isEqualToString:@"iPod1,1"]) return @"iPod Touch 1G";
  if ([deviceModel isEqualToString:@"iPod2,1"]) return @"iPod Touch 2G";
  if ([deviceModel isEqualToString:@"iPod3,1"]) return @"iPod Touch 3G";
  if ([deviceModel isEqualToString:@"iPod4,1"]) return @"iPod Touch 4G";
  if ([deviceModel isEqualToString:@"iPod5,1"]) return @"iPod Touch 5G";

  //iPad 系列
  if ([deviceModel isEqualToString:@"iPad1,1"]) return @"iPad";
  if ([deviceModel isEqualToString:@"iPad2,1"]) return @"iPad 2 (WiFi)";
  if ([deviceModel isEqualToString:@"iPad2,2"]) return @"iPad 2 (GSM)";
  if ([deviceModel isEqualToString:@"iPad2,3"]) return @"iPad 2 (CDMA)";
  if ([deviceModel isEqualToString:@"iPad2,4"]) return @"iPad 2 (32nm)";
  if ([deviceModel isEqualToString:@"iPad2,5"]) return @"iPad mini (WiFi)";
  if ([deviceModel isEqualToString:@"iPad2,6"]) return @"iPad mini (GSM)";
  if ([deviceModel isEqualToString:@"iPad2,7"]) return @"iPad mini (CDMA)";

  if ([deviceModel isEqualToString:@"iPad3,1"]) return @"iPad 3(WiFi)";
  if ([deviceModel isEqualToString:@"iPad3,2"]) return @"iPad 3(CDMA)";
  if ([deviceModel isEqualToString:@"iPad3,3"]) return @"iPad 3(4G)";
  if ([deviceModel isEqualToString:@"iPad3,4"]) return @"iPad 4 (WiFi)";
  if ([deviceModel isEqualToString:@"iPad3,5"]) return @"iPad 4 (4G)";
  if ([deviceModel isEqualToString:@"iPad3,6"]) return @"iPad 4 (CDMA)";

  if ([deviceModel isEqualToString:@"iPad4,1"]) return @"iPad Air";
  if ([deviceModel isEqualToString:@"iPad4,2"]) return @"iPad Air";
  if ([deviceModel isEqualToString:@"iPad4,3"]) return @"iPad Air";
  if ([deviceModel isEqualToString:@"iPad5,3"]) return @"iPad Air 2";
  if ([deviceModel isEqualToString:@"iPad5,4"]) return @"iPad Air 2";
  if ([deviceModel isEqualToString:@"i386"]) return @"Simulator";
  if ([deviceModel isEqualToString:@"x86_64"]) return @"Simulator";

  if ([deviceModel isEqualToString:@"iPad4,4"]
  ||[deviceModel isEqualToString:@"iPad4,5"]
  ||[deviceModel isEqualToString:@"iPad4,6"]) return @"iPad mini 2";

  if ([deviceModel isEqualToString:@"iPad4,7"]
  ||[deviceModel isEqualToString:@"iPad4,8"]
  ||[deviceModel isEqualToString:@"iPad4,9"]) return @"iPad mini 3";

  return deviceModel;
  }
  记得必定要#import <sys/utsname.h>啊，到时候没有导入编译不经过了不要找我啊。

Swift代码获取iOS设备型号：
//MARK: - UIDevice延展
public 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 where value != 0 else { return identifier }
        return identifier + String(UnicodeScalar(UInt8(value)))
    }

    switch identifier {
    case "iPod5,1":                                 return "iPod Touch 5"
    case "iPod7,1":                                 return "iPod Touch 6"
    case "iPhone3,1", "iPhone3,2", "iPhone3,3":     return "iPhone 4"
    case "iPhone4,1":                               return "iPhone 4s"
    case "iPhone5,1", "iPhone5,2":                  return "iPhone 5"
    case "iPhone5,3", "iPhone5,4":                  return "iPhone 5c"
    case "iPhone6,1", "iPhone6,2":                  return "iPhone 5s"
    case "iPhone7,2":                               return "iPhone 6"
    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
    }
}

}
这个是在 Swift 2.0 版本以后才能使用的：如今不会还有人使用 Swift 1.2 吧？

你还问我怎么用？好吧，骚年，送佛送到西，您看好了，把上面的扩展扔到你的项目中，而后就能够用下面的语句调用了：

let modelName = UIDevice.currentDevice().modelName

好了，今天就写到这儿吧，但愿之后还有时间有精力来更多的更新一些内容吧。
