获取iOS设备信息(内存/电量/容量/型号/IP地址/当前WIFI名称)

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];

}

8.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:@"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 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;

}

10.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;

}
