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：

点击下载以上展示效果的GitHub源码

• 一行代码就搞定的统一来！

    // 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);

• 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

//广告标识 
NSString *idfa = [[[ASIdentifierManager sharedManager] advertisingIdentifier] UUIDString];
  NSLog(@"广告位标识符idfa-->%@", idfa);

• 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。

 //UUID
 NSString *uuid = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
 NSLog(@"唯一识别码uuid-->%@", uuid);

• 获取设备型号

// 获取设备型号然后手动转化为对应名称
- (NSString *)getDeviceName
{
    // 需要#import "sys/utsname.h"
