获取iOS设备信息(内存/电量/容量/型号/IP地址/当前WIFI名称)

来源：互联网发布：access数据库程序设计编辑：程序博客网时间：2024/05/29 02:23

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;}

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];    }}

8.型号

#import <sys/sysctl.h>

+ (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:@"iPhone4,1"]) return @"iPhone 4s (A1387/A1431)";    if ([platform isEqualToString:@"iPhone5,1"]) return @"iPhone 5 (A1428)";    if ([platform isEqualToString:@"iPhone5,2"]) return @"iPhone 5 (A1429/A1442)";    if ([platform isEqualToString:@"iPhone5,3"]) return @"iPhone 5c (A1456/A1532)";    if ([platform isEqualToString:@"iPhone5,4"]) return @"iPhone 5c (A1507/A1516/A1526/A1529)";    if ([platform isEqualToString:@"iPhone6,1"]) return @"iPhone 5s (A1453/A1533)";    if ([platform isEqualToString:@"iPhone6,2"]) return @"iPhone 5s (A1457/A1518/A1528/A1530)";    if ([platform isEqualToString:@"iPhone7,1"]) return @"iPhone 6 Plus (A1522/A1524)";    if ([platform isEqualToString:@"iPhone7,2"]) return @"iPhone 6 (A1549/A1586)";    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:@"iPad2,7"])   return @"iPad Mini 1G (A1455)";    if ([platform isEqualToString:@"iPad3,1"])   return @"iPad 3 (A1416)";    if ([platform isEqualToString:@"iPad3,2"])   return @"iPad 3 (A1403)";    if ([platform isEqualToString:@"iPad3,3"])   return @"iPad 3 (A1430)";    if ([platform isEqualToString:@"iPad3,4"])   return @"iPad 4 (A1458)";    if ([platform isEqualToString:@"iPad3,5"])   return @"iPad 4 (A1459)";    if ([platform isEqualToString:@"iPad3,6"])   return @"iPad 4 (A1460)";    if ([platform isEqualToString:@"iPad4,1"])   return @"iPad Air (A1474)";    if ([platform isEqualToString:@"iPad4,2"])   return @"iPad Air (A1475)";    if ([platform isEqualToString:@"iPad4,3"])   return @"iPad Air (A1476)";    if ([platform isEqualToString:@"iPad4,4"])   return @"iPad Mini 2G (A1489)";    if ([platform isEqualToString:@"iPad4,5"])   return @"iPad Mini 2G (A1490)";    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。

9.IP地址

#import <ifaddrs.h>和#import <arpa/inet.h>

- (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;}

10.当前手机连接的WIFI名称(SSID)

需要#import <SystemConfiguration/CaptiveNetwork.h>

- (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;}
