    1.获取电池电量(一般用百分数表示,大家自行处理就好)
    - (CGFloat)getBatteryQuantity
    {
        return [[UIDevice currentDevice] batteryLevel];
    }
    
    2.获取电池状态(UIDeviceBatteryState为枚举类型)
    - (UIDeviceBatteryState)getBatteryStauts
    {    
        return [UIDevice currentDevice].batteryState;
    }
    
    3.获取总内存大小
    - (long long)getTotalMemorySize
    {    
        return [NSProcessInfo processInfo].physicalMemory;
    }
    
    4.获取当前可用内存
    - (long long)getAvailableMemorySize
    {
        vm_statistics_data_t vmStats;  
        mach_msg_type_number_t infoCount = HOST_VM_INFO_COUNT;
        kern_return_t kernReturn = host_statistics(mach_host_self(), HOST_VM_INFO, (host_info_t)&vmStats, &infoCount);
        if  (kernReturn != KERN_SUCCESS)  {
            return NSNotFound;
        }
        return ((vm_page_size * vmStats.free_count + vm_page_size * vmStats.inactive_count));
    }
    
    5.获取已使用内存
    - (double)getUsedMemory
    {
      task_basic_info_data_t taskInfo;
      mach_msg_type_number_t infoCount = TASK_BASIC_INFO_COUNT;
      kern_return_t kernReturn = task_info(mach_task_self(), TASK_BASIC_INFO, (task_info_t)&taskInfo, &infoCount);
      if (kernReturn != KERN_SUCCESS)  {
      return NSNotFound;
      }
      return taskInfo.resident_size;
    }
    
    6.获取总磁盘容量
    include <sys mount.h="">
    - (long long)getTotalDiskSize
    {
        struct statfs buf;
        unsigned long long freeSpace = -1;
        if (statfs("/var", &buf) >= 0) {
            freeSpace = (unsigned long long)(buf.f_bsize * buf.f_blocks);
        }
        return freeSpace;
    }</sys>
    
    7.获取可用磁盘容量
    - (long long)getAvailableDiskSize
    {
        struct statfs buf;
        unsigned long long freeSpace = -1;
        if (statfs("/var", &buf) >= 0) {
        freeSpace = (unsigned long long)(buf.f_bsize * buf.f_bavail);
        }
        return freeSpace;
    }
    
    8.容量转换
    - (NSString *)fileSizeToString:(unsigned long long)fileSize
    {
        NSInteger KB = 1024;
        NSInteger MB = KB*KB;
        NSInteger GB = MB*KB;
        if (fileSize < 10)  {
            return @"0 B";
        } else  if (fileSize < KB)    {
            return @"< 1 KB";
        } else if (fileSize < MB)    {
            return [NSString stringWithFormat:@"%.1f KB", ((CGFloat)fileSize)/KB];
        } else if (fileSize < GB)    {
            return [NSString stringWithFormat:@"%.1f MB"
    ,((CGFloat)fileSize)/MB];
        } else {
            return [NSString stringWithFormat:@"%.1f GB",((CGFloat)fileSize)/GB]; 
        }
    }
    
    9.型号
    #import
    + (NSString *)getCurrentDeviceModel:(UIViewController *)controller {
        int mib[2];
        size_t len;
        char *machine;
        mib[0] = CTL_HW;
        mib[1] = HW_MACHINE;
        sysctl(mib, 2, NULL, &len, NULL, 0);
        machine = malloc(len);
        sysctl(mib, 2, machine, &len, NULL, 0);
        NSString *platform = [NSString stringWithCString:machine encoding:NSASCIIStringEncoding];
        free(machine);
    
        if ([platform isEqualToString:@"iPhone3,1"]) return @"iPhone 4 (A1332)";
        if ([platform isEqualToString:@"iPhone3,2"]) return @"iPhone 4 (A1332)";
        if ([platform isEqualToString:@"iPhone3,3"]) return @"iPhone 4 (A1349)";

        if ([platform isEqualToString:@"iPhone8,1"]) return @"iPhone 6s";
        if ([platform isEqualToString:@"iPhone8,2"]) return @"iPhone 6s Plus";
        if ([platform isEqualToString:@"iPod1,1"])   return @"iPod Touch 1G (A1213)";
        if ([platform isEqualToString:@"iPod2,1"])   return @"iPod Touch 2G (A1288)";
        if ([platform isEqualToString:@"iPod3,1"])   return @"iPod Touch 3G (A1318)";
        if ([platform isEqualToString:@"iPod4,1"])   return @"iPod Touch 4G (A1367)";
        if ([platform isEqualToString:@"iPod5,1"])   return @"iPod Touch 5G (A1421/A1509)";
    
        if ([platform isEqualToString:@"iPad1,1"])   return @"iPad 1G (A1219/A1337)";
        if ([platform isEqualToString:@"iPad2,1"])   return @"iPad 2 (A1395)";
        if ([platform isEqualToString:@"iPad2,2"])   return @"iPad 2 (A1396)";
        if ([platform isEqualToString:@"iPad2,3"])   return @"iPad 2 (A1397)";
        if ([platform isEqualToString:@"iPad2,4"])   return @"iPad 2 (A1395+New Chip)";
        if ([platform isEqualToString:@"iPad2,5"])   return @"iPad Mini 1G (A1432)";
        if ([platform isEqualToString:@"iPad2,6"])   return @"iPad Mini 1G (A1454)";

        if ([platform isEqualToString:@"iPad4,6"])   return @"iPad Mini 2G (A1491)";
    
        if ([platform isEqualToString:@"i386"])      return @"iPhone Simulator";
        if ([platform isEqualToString:@"x86_64"])    return @"iPhone Simulator";
        return platform;
    }
    
    

    可以根据自己的需求增改。有人说也可以按照手机屏幕来判断,但5和5s/5c等手机屏幕相同尺寸则无法判断。。。我只做了iPhone的机型,所以iPad和iPod Touch的信息并没有更新到最新,也请朋友们补充。

    10.IP地址
    #import 和 #import 
    - (NSString *)deviceIPAdress {
        NSString *address = @"an error occurred when obtaining ip address";
        struct ifaddrs *interfaces = NULL;
        struct ifaddrs *temp_addr = NULL;
        int success = 0;
        success = getifaddrs(&interfaces);
        if (success == 0) { // 0 表示获取成功
            temp_addr = interfaces;
            while (temp_addr != NULL) {    
                if( temp_addr->ifa_addr->sa_family == AF_INET) {
                    // Check if interface is en0 which is the wifi connection on the iPhone
                    if ([[NSString stringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"en0"]) {
                        // Get NSString from C String
                        address = [NSString stringWithUTF8String:inet_ntoa(((struct sockaddr_in *)temp_addr->ifa_addr)->sin_addr)];
                    }
                }
                temp_addr = temp_addr->ifa_next;
            }
        }
        freeifaddrs(interfaces);
        return address;
    }
    
    11.当前手机连接的WIFI名称(SSID)
    需要#import 
    - (NSString *)getWifiName
    {
        NSString *wifiName = nil;
        CFArrayRef wifiInterfaces = CNCopySupportedInterfaces();
        if (!wifiInterfaces) {   
            return nil;
        }
        NSArray *interfaces = (__bridge NSArray *)wifiInterfaces;
        for (NSString *interfaceName in interfaces) {
            CFDictionaryRef dictRef = CNCopyCurrentNetworkInfo((__bridge CFStringRef)(interfaceName));
            if (dictRef) {
                NSDictionary *networkInfo = (__bridge NSDictionary *)dictRef;
                wifiName = [networkInfo objectForKey:(__bridge NSString *)kCNNetworkInfoKeySSID];
                CFRelease(dictRef);
            }
        }
        CFRelease(wifiInterfaces);
        return wifiName;
    }
