更新至iPhone X 新增设备颜色的获取

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);// 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);
复制代码

• 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
- (NSString *)getDeviceName
{// 需要#import "sys/utsname.h"#warning 题主呕心沥血总结！！最全面！亲测！全网独此一份！！struct utsname systemInfo;uname(&systemInfo);NSString *deviceString = [NSString stringWithCString:systemInfo.machine

• 获取 iPhone 设备颜色/外壳颜色

#warning 该方法是私有API，上线会被拒
// 由于每款手机同一颜色具体色号不一样，如 iPhone 6和 iPhone SE粉色的两个具体色值是不一样的，因此在这里只能返回一个色号
UIDevice *device = [UIDevice currentDevice];
SEL selector = NSSelectorFromString(@"deviceInfoForKey:");
if (![device respondsToSelector:selector]) {selector = NSSelectorFromString(@"_deviceInfoForKey:");
}
