·开发中，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。
OC代码：
NSString *deviceName = [[UIDevice currentDevice] name]; //获取设备名称 例如：梓辰的手机
NSString *sysVersion = [[UIDevice currentDevice] systemName]; //获取系统名称 例如：iPhone OS
NSString *sysVersion = [[UIDevice currentDevice] systemVersion]; //获取系统版本 例如：9.2
NSString *deviceUUID = [[[UIDevice currentDevice] identifierForVendor] UUIDString]; //获取设备唯一标识符 例如：FBF2306E-A0D8-4F4B-BDED-9333B627D3E6
NSString *deviceModel = [[UIDevice currentDevice] model]; //获取设备的型号 例如：iPhone
获取App 相关信息
NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];
NSString *appVersion = [infoDic objectForKey:@"CFBundleShortVersionString"]; // 获取App的版本
NSString *appBuildVersion = [infoDic objectForKey:@"CFBundleVersion"]; // 获取App的build版本
NSString *appName = [infoDic objectForKey:@"CFBundleDisplayName"]; // 获取App的名称
Swift代码：
let deviceName = UIDevice.currentDevice().name //获取设备名称 例如：梓辰的手机
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：FBF2306E-A0D8-4F4B-BDED-9333B627D3E6
let deviceModel = UIDevice.currentDevice().model //获取设备的型号 例如：iPhone
获取App 相关信息
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
看到这里，你是不是有点失望，是不是没有你最想找到的，就是获取设备型号，获取出来一个iPhone，你确定不是在逗我吧？
看官别急，其实这次分享最主要的就是设备型号，作为给大家的分享，也是我自己做个笔记。
iOS获取具体的设备型号
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];

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：

你不会还要问我怎么用吧？好吧，用用给你看：
let modelName = UIDevice.currentDevice().modelName
