iOS获取设备型号和App版本号等信息（OC＋Swift）
字数1687 阅读382 评论3 喜欢10 好久没有写过博客了，因为中间工作比较忙，然后有些个人事情所以耽误了。但是之前写的博客还一直有人来问一些问题，有些之前写的已经比较久了，有些需要实时更新的也没来得及更新，发现会跟一些童鞋造成困惑，所以以后也希望能及时更新和写一些新的内容。我之前博客的地址：一毛的博客，也是主要介绍iOS开发的，以后都在简书更新吧。希望大家能继续支持。
iOS开发过程中，有时候为了更好的用户体验或者为了bug跟踪，可能会需要获取用户的应用信息、系统信息、设备信息。这些信息的获取可以根据不同的设备或者App、系统版本来提供不同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原因。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获取设备唯一标识符
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！看你之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？尤其是获取设备型号那个，获取出来一个iPhone，你确定不是在逗我吧？”看官别急，其实这次最主要的就是来分享获取设备型号的方法的，因为我看国内还很少有Swift写的一些东西，也不知道是不是因为我没有找到，就想自己写出来给大家分享，顺便做个笔记。
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，而且还得记住所有设备版本号例如：iPhone8,2，实在是记不住啊。当然不用记住，用的时候拷过来就行了，因为我也记不住?
iOS获取具体设备型号
OC代码获取iOS设备型号： // 需要#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;
} 记得一定要#import <sys/utsname.h>啊，到时候没有导入编译不通过了不要找我啊。
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 版本之后才能使用的：现在不会还有人使用 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，然后就可以用下面的语句调用了：
let modelName = UIDevice.currentDevice().modelName
好了，今天就写到这儿吧，希望以后还有时间有精力来更多的更新一些内容吧。
