为了统计用户信息、下发广告，服务器端往往需要手机用户设备及app的各种信息，下面讲述一下各种信息的获取方式：
// 这个方法后面会列出来
NSString *deviceName = [self getDeviceName];
NSLog(@ "设备型号-->%@" , deviceName);
NSString *iPhoneName = [UIDevice currentDevice].name;
NSLog(@ "iPhone名称-->%@" , iPhoneName);
NSString *appVerion = [[[NSBundle mainBundle] infoDictionary] objectForKey:@ "CFBundleShortVersionString" ];
NSLog(@ "app版本号-->%@" , appVerion);
CGFloat batteryLevel = [[UIDevice currentDevice] batteryLevel];
NSLog(@ "电池电量-->%f" , batteryLevel);
NSString *localizedModel = [UIDevice currentDevice].localizedModel;
NSLog(@ "localizedModel-->%@" , localizedModel);
NSString *systemName = [UIDevice currentDevice].systemName;
NSLog(@ "当前系统名称-->%@" , systemName);
NSString *systemVersion = [UIDevice currentDevice].systemVersion;
NSLog(@ "当前系统版本号-->%@" , systemVersion);
struct utsname systemInfo;
uname(&systemInfo);
NSString *device_model = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
NSLog(@ "device_model-->%@" , device_model);
// 这个方法后面会单独列出
NSString *macAddress = [self getMacAddress];
NSLog(@ "macAddress-->%@" , macAddress);
// 这个方法后面会单独列出
NSString *deviceIP = [self getDeviceIPAddresses];
NSLog(@ "deviceIP-->%@" , deviceIP);
// 设备上次重启的时间
NSTimeInterval time = [[NSProcessInfo processInfo] systemUptime];
NSDate *lastRestartDate = [[NSDate alloc] initWithTimeIntervalSinceNow:( 0 - time)];- 一行代码就搞定的统一来！
- 广告位标识符：在同一个设备上的所有App都会取到相同的值，是苹果专门给各广告提供商用来追踪用户而设的，用户可以在 设置|隐私|广告追踪里重置此id的值，或限制此id的使用，故此id有可能会取不到值，但好在Apple默认是允许追踪的，而且一般用户都不知道有这么个设置，所以基本上用来监测推广效果，是戳戳有余了

- UUID是Universally Unique Identifier的缩写，中文意思是通用唯一识别码。它是让分布式系统中的所有元素，都能有唯一的辨识资讯，而不需要透过中央控制端来做辨识资讯的指 定。这样，每个人都可以建立不与其它人冲突的 UUID。在此情况下，就不需考虑数据库建立时的名称重复问题。苹果公司建议使用UUID为应用生成唯一标识字符串。
