获取苹果设备和系统信息（更新至iPhone X）

1.获得设备型号

#import <sys/utsname.h>

+ (NSString *)getCurrentDeviceModel
{
struct utsname systemInfo;
uname(&systemInfo);
NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSASCIIStringEncoding];

// iPhone
if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone2G";
if ([platform isEqualToString:@"iPhone1,2"]) return @"iPhone3G";
if ([platform isEqualToString:@"iPhone2,1"]) return @"iPhone3GS";

if ([platform isEqualToString:@"iPad5,2"]) return @"iPadmini4";

if ([platform isEqualToString:@"i386"]) return @"iPhoneSimulator";
if ([platform isEqualToString:@"x86_64"]) return @"iPhoneSimulator";

return platform;
}

2.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];
}

3.获取电池状态(UIDeviceBatteryState为枚举类型)
-(UIDeviceBatteryState)getBatteryStauts
{
return [UIDevice currentDevice].batteryState;
}
4.获取总内存大小
-(long long)getTotalMemorySize
{
return [NSProcessInfo processInfo].physicalMemory;
}
5.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));
}
6.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;
}
7.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;
}
8.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;
}
9.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];
}
}
10.IP地址
- (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)
- (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;
}

12.设备基本信息
NSLog(@"%@",[[UIDevice currentDevice] name]);//设备名称
NSLog(@"%@",[[UIDevice currentDevice] model]);//设备类型
NSLog(@"%@",[[UIDevice currentDevice] localizedModel]);
NSLog(@"%@",[[UIDevice currentDevice] systemName]);//系统名称
NSLog(@"%@",[[UIDevice currentDevice] systemVersion]);//系统版本
