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:@"iPhone8,2"]) return @"iPhone 6s Plus";
if ([deviceModel isEqualToString:@"iPhone9,1"]) return @"iPhone 7 (CDMA)";
if ([deviceModel isEqualToString:@"iPhone9,3"]) return @"iPhone 7 (GSM)";
if ([deviceModel isEqualToString:@"iPhone9,2"]) return @"iPhone 7 Plus (CDMA)";
if ([deviceModel isEqualToString:@"iPhone9,4"]) return @"iPhone 7 Plus (GSM)";
//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 "iPhone9,1": return "iPhone 7 (CDMA)"
case "iPhone9,3": return "iPhone 7 (GSM)"
case "iPhone9,2": return "iPhone 7 Plus (CDMA)"
case "iPhone9,4": return "iPhone 7 Plus (GSM)"
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。
再次谢谢大家的支持！也希望哪儿有写的不对的地方，欢迎大家批评指正。
