获取当前设备

    //获取当前设备    UIDevice *dev = [UIDevice currentDevice];

设备和系统基本信息

    NSLog(@"设备名称：%@", dev.name);  NSLog(@"设备类型：%@", dev.model);  NSLog(@"本地化模式：%@", dev.localizedModel); NSLog(@"系统名称:%@", dev.systemName);   NSLog(@"系统版本：%@", dev.systemVersion);   NSLog(@"设备朝向：%ld", dev.orientation); NSLog(@"UUID:%@", dev.identifierForVendor.UUIDString);

设备类型判断

    //判断设备种类if (dev.userInterfaceIdiom == UIUserInterfaceIdiomPhone) {             NSLog(@"iPhone 设备");}else if(dev.userInterfaceIdiom == UIUserInterfaceIdiomPad){               NSLog(@"iPad 设备");} else if (dev.userInterfaceIdiom == UIUserInterfaceIdiomTV){             NSLog(@"Apple TV设备");} else{             NSLog(@"未知设备！！");}

电池相关信息

    //设置电池是否被监视dev.batteryMonitoringEnabled = YES;    //判断当前电池状态if (dev.batteryState == UIDeviceBatteryStateUnknown) {            NSLog(@"UnKnow");}else if (dev.batteryState == UIDeviceBatteryStateUnplugged){           NSLog(@"未充电");}else if (dev.batteryState == UIDeviceBatteryStateCharging){          NSLog(@"正在充电，电量未满");}else if (dev.batteryState == UIDeviceBatteryStateFull){            NSLog(@"正在充电，电量已满");}    //当前电量等级 [0.0, 1.0]NSLog(@"%f",dev.batteryLevel);  UIDeviceBatteryLevelDidChangeNotification//电池状态改变通知UIDeviceBatteryStateDidChangeNotification//以上两个通知需在 batteryMonitoringEnabled 设置为YES的情况下有效

红外线感应

    //开启红外感应-- 用于检测手机是否靠近面部dev.proximityMonitoringEnabled = YES;      if (dev.proximityState == YES) {            NSLog(@"靠近面部");} else{               NSLog(@"没有靠近");}

多任务环境监测

    //判断当前系统是否支持多任务if (dev.isMultitaskingSupported == YES) {         NSLog(@"支持多任务!!!");} else{            NSLog(@"不支持多任务！！！");}
