史上最全的iOS各种设备信息获取总结(iPhone8/iPhone X 已更新)

原文:选自cocoaChina

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:

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);


   // 设备上次重启的时间

   NSTimeInterval time = [[NSProcessInfo processInfo] systemUptime];

   NSDate *lastRestartDate = [[NSDate alloc] initWithTimeIntervalSinceNow:(0- time)];

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

   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。

 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
