1. 获取设备的相关信息
基本信息
[[UIDevice currentDevice] systemName]; // 系统名 e.g. @"iOS"
[[UIDevice currentDevice] systemVersion]; // 版本号 e.g. @"9.3"
[[UIDevice currentDevice] model]; // 设备类型 e.g. @"iPhone", @"iPod touch"
[[UIDevice currentDevice] name]; // 设备名称 eg. @"Jaesun"
[[UIDevice currentDevice] localizedModel]; // 本地模式
[[UIDevice currentDevice] batteryLevel]; // 设备剩余电量(满状态为 1.0) eg. 0.55
设备型号
新增型号与名称对应表在官网：https://www.theiphonewiki.com/wiki/Models 可查
// 需要引入头文件
#import "sys/utsname.h"
/**
* 获取设备硬件类型并转化为熟知的硬件类型名称
* 参照 ：https://www.theiphonewiki.com/wiki/Models
* @return 硬件类型俗称
*/
- (NSString*)deviceModelDetail {
struct utsname systemInfo;
uname(&systemInfo);
NSString *deviceModelDetail = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
if ([deviceModelDetail isEqualToString:@"iPhone8,4"]) return @"iPhone SE";
if ([deviceModelDetail isEqualToString:@"iPhone8,2"]) return @"iPhone 6s Plus";
if ([deviceModelDetail isEqualToString:@"iPhone8,1"]) return @"iPhone 6s";
if ([deviceModelDetail isEqualToString:@"iPhone7,1"]) return @"iPhone 6 Plus";

if ([deviceModelDetail isEqualToString:@"i386"]) return @"Simulator";
if ([deviceModelDetail isEqualToString:@"x86_64"]) return @"Simulator";
return deviceModelDetail;
}
系统语言信息
// 获取设备系统当前语言
- (NSString *)preferredLanguage
{
NSArray *languages = [NSLocale preferredLanguages];
NSString * preferredLanguage = [languages objectAtIndex:0];
return preferredLanguage;
}
内存，磁盘空间相关信息
//需要 引入头文件
#include <mach/mach.h>
#include <sys/param.h>
#include <sys/mount.h>
（1）-获取内存(运行内存)总容量，和内存可用容量
/**
* 获取内存总容量(运行内存)
*
* @return
*/
-(long long)totalMemoryLength
{
return [NSProcessInfo processInfo].physicalMemory;
}
/**
* 获取可用内存
*
* @return
*/
-(long long)freeMemorylength
{
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));
}
（2）-获取磁盘(储空间内存,我们应用存储数据文件的地方)总容量，和磁盘可用容量
/**
* 获取总磁盘容量(存储内存)
*
* @return
*/
-(long long)totalDiskSize
{
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;
}
/**
* 获取可用磁盘容量
*
* @return
*/
-(long long)freeDiskLength
{
struct statfs buf;
unsigned long long freeLength = -1;
if (statfs("/var", &buf) >= 0)
{
freeLength = (unsigned long long)(buf.f_bsize * buf.f_bavail);
}
return freeLength;
}
获取设备IP
引入头文件
#import <sys/socket.h>
#import <sys/sockio.h>
#import <sys/ioctl.h>
#import <net/if.h>
#import <arpa/inet.h>
获取设备当前网络环境下的IP地址
/**
* 获取设备IP
*/
- (NSString* )deceiveIP {
int sockfd = socket(AF_INET, SOCK_DGRAM, 0);
if (sockfd < 0) return nil;
NSMutableArray *ips = [NSMutableArray array];
int BUFFERSIZE = 4096;
struct ifconf ifc;
char buffer[BUFFERSIZE], *ptr, lastname[IFNAMSIZ], *cptr;
struct ifreq *ifr, ifrcopy;
ifc.ifc_len = BUFFERSIZE;
ifc.ifc_buf = buffer;
if (ioctl(sockfd, SIOCGIFCONF, &ifc) >= 0) {
for (ptr = buffer; ptr < buffer + ifc.ifc_len; ) {
ifr = (struct ifreq *)ptr;
int len = sizeof(struct sockaddr);
if (ifr->ifr_addr.sa_len > len) {
len = ifr->ifr_addr.sa_len;
}
ptr += sizeof(ifr->ifr_name) + len;
if (ifr->ifr_addr.sa_family != AF_INET) continue;
if ((cptr = (char *)strchr(ifr->ifr_name, ':')) != NULL) *cptr = 0;
if (strncmp(lastname, ifr->ifr_name, IFNAMSIZ) == 0) continue;
memcpy(lastname, ifr->ifr_name, IFNAMSIZ);
ifrcopy = *ifr;
ioctl(sockfd, SIOCGIFFLAGS, &ifrcopy);
if ((ifrcopy.ifr_flags & IFF_UP) == 0) continue;
NSString *ip = [NSString stringWithFormat:@"%s", inet_ntoa(((struct sockaddr_in *)&ifr->ifr_addr)->sin_addr)];
[ips addObject:ip];
}
}
close(sockfd);
NSString *deviceIP = @"";
for (int i=0; i < ips.count; i++) {
if (ips.count > 0) {
deviceIP = [NSString stringWithFormat:@"%@",ips.lastObject];
}
}
return deviceIP;
}
2. 获取应用的相关信息
基本信息
//app应用相关信息的获取
NSDictionary *dicInfo = [[NSBundle mainBundle] infoDictionary];
// 当前应用名称
[dicInfo objectForKey:@"CFBundleDisplayName"];
// 当前应用软件版本 比如：1.0.1
[dicInfo objectForKey:@"CFBundleShortVersionString"];
// 当前应用版本号码 int类型
[dicInfo objectForKey:@"CFBundleVersion"];
获取Appstore中应用相关信息 -- 如 : 版本号等信息
相关数据从 https://itunes.apple.com/lookup?id=（应用的Apple id）获取， 应用的Apple id 在iTunes Connect--APP信息中查看
- (void)versionInAppStore {
NSURL *url = [NSURL URLWithString:@"https://itunes.apple.com/lookup?id=533314804"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if (data) {
// appStore 中应用相关信息
NSString *JSONStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"JSONStr IS %@",JSONStr);
NSDictionary *JSONDic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];
// 可以获取已经上架的而应用版本号
NSString *versionInStore = [[[JSONDic objectForKey:@"results"] objectAtIndex:0] objectForKey:@"version"];
}
}];
[dataTask resume];
}
