获得iOS设备信息-电池,内存,cpu,磁盘等

 

以下内容从他处获得,于大家分享


电池信息可以从UIDevice batteryLevel得到,但是只能精确到0.05.
– (NSDictionary*)batteryLevel
{
CFTypeRef blob = IOPSCopyPowerSourcesInfo();
       CFArrayRef sources = IOPSCopyPowerSourcesList(blob);
       
       CFDictionaryRef pSource = NULL;
       const void *psValue;
       
       int numOfSources = CFArrayGetCount(sources);
       if (numOfSources == 0)
       {
               CFRelease(blob);
               CFRelease(sources);
               NSLog(@”qhk: Error in CFArrayGetCount”);
               return nil;
       }
       
       for (int i = 0 ; i < numOfSources ; i++)
       {
               pSource = IOPSGetPowerSourceDescription(blob, CFArrayGetValueAtIndex(sources, i));
               if (!pSource)
               {
                       CFRelease(blob);
                       CFRelease(sources);
                       NSLog(@”qhk: Error in IOPSGetPowerSourceDescription”);
                       return nil;
               }
               
               psValue = (CFStringRef)CFDictionaryGetValue(pSource, CFSTR(kIOPSNameKey));
               
               int curCapacity = 0;
               int maxCapacity = 0;
//                double percent;
               
               psValue = CFDictionaryGetValue(pSource, CFSTR(kIOPSCurrentCapacityKey));
               CFNumberGetValue((CFNumberRef)psValue, kCFNumberSInt32Type, &curCapacity);
               
               psValue = CFDictionaryGetValue(pSource, CFSTR(kIOPSMaxCapacityKey));
               CFNumberGetValue((CFNumberRef)psValue, kCFNumberSInt32Type, &maxCapacity);
               
//                percent = ((double)curCapacity/(double)maxCapacity * 100.0f);
               
               NSNumber* no1 = [NSNumber numberWithInt:curCapacity];
               NSNumber* no2= [NSNumber numberWithInt:maxCapacity];
               
               CFRelease(blob);
               CFRelease(sources);
               
               return [NSDictionary dictionaryWithObjectsAndKeys:no1, @”no1″, no2, @”no2″, nil];
               
//                return percent;
//                return (NSInteger)(percent + 0.5f);
       }
//#endif
       
       CFRelease(blob);
       CFRelease(sources);
       
       return nil;
}

这个可以精确到0.01,但是好像与系统显示的仍有偏差。




得到平台号:
– (NSString*) doDevicePlatform
{
   size_t size;
   int nR = sysctlbyname(“hw.machine”, NULL, &size, NULL, 0);
   char *machine = (char *)malloc(size);
   nR = sysctlbyname(“hw.machine”, machine, &size, NULL, 0);
   NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];
   free(machine);
   return platform;
}
在根据平台号得到手机型号:
比如:

  if ([platform isEqualToString:@”iPhone1,1″])
   {
       return @”iPhone”;
   }
   if ([platform isEqualToString:@”iPhone1,2″])
   {
       return @”iPhone3G”;
   }
   if ([platform isEqualToString:@”iPhone2,1″])
   {
       return @”iPhone3GS”;
   }
   if ([platform isEqualToString:@”iPhone3,1″])
   {
       return @”iPhone4″;
   }






得到mac地址:

– (void)printmacinfo
{
       bool success;
       struct ifaddrs *addrs;
       const struct ifaddrs *cursor;
       const struct sockaddr_dl *dlAddr;
       const uint8_t *base;
       
       success = getifaddrs(&addrs) == 0;
       if (success)
       {
               cursor = addrs;
               NSInteger idx = 0;
               while (cursor != NULL)
               {
                       ++idx;
                       NSString* macTitle = nil;
                       if ((cursor->ifa_flags & IFF_LOOPBACK) == 0 )
                       {
                               char* ifaname = (char *)cursor->ifa_name;
                               char* addr = inet_ntoa(((struct sockaddr_in *)cursor->ifa_addr)->sin_addr);
                               printf(“%s “, ifaname);
                               printf(“%s\n”, addr);
//                                NSString* tmpstr1 = [NSString stringWithCString:ifaname encoding:NSUTF8StringEncoding];
//                                NSString* tmpstr2 = [NSString stringWithCString:addr encoding:NSUTF8StringEncoding];
//                                NSString *tmpStr = [NSString stringWithFormat:@”%@ %@”, tmpstr1, tmpstr2];
                               
                               macTitle = [NSString stringWithFormat:@”%d %s %s”, idx, ifaname, addr];
                               
                               [_arrKey addObject:macTitle];
                       }
                       if ( (cursor->ifa_addr->sa_family == AF_LINK)
                               && (((const struct sockaddr_dl *) cursor->ifa_addr)->sdl_type ==IFT_ETHER)
                               )
                       {
                               dlAddr = (const struct sockaddr_dl *) cursor->ifa_addr;
                               // fprintf(stderr, ” sdl_nlen = %d\n”, dlAddr->sdl_nlen);
                               // fprintf(stderr, ” sdl_alen = %d\n”, dlAddr->sdl_alen);
                               base = (const uint8_t *) &dlAddr->sdl_data[dlAddr->sdl_nlen];
                               printf(” MAC address “);
                               NSMutableString* tmpString = [[[NSMutableString alloc] initWithString:@”Mac:”] autorelease];
                               for (int i = 0; i < dlAddr->sdl_alen; i++)
                               {
                                       if (i != 0)
                                       {
                                               printf(“:”);
                                               [tmpString appendString:@”:”];
                                       }
                                       printf(“x”, base);
                                       [tmpString appendFormat:@”X”, base];
                               } 
                               printf(“\n”);
                               [_dic setObject:tmpString forKey:macTitle];
                       }
                       else if (macTitle != nil)
                       {
                               [_dic setObject:@”” forKey:macTitle];
                       }
                       cursor = cursor->ifa_next;
               }
       }
}







得到4种内存信息:

       mach_msg_type_number_t count = HOST_VM_INFO_COUNT;
       vm_statistics_data_t vmstat;
       if (host_statistics(mach_host_self(), HOST_VM_INFO, (host_info_t)&vmstat, &count) != KERN_SUCCESS)
       {
               NSLog(@”Failed to get VM statistics.”);
               [_dic setObject:@”Failed to get VM statistics.” forKey:KTTMemorySize_Wire];
       }
       else
       {
               float total = vmstat.wire_count + vmstat.active_count + vmstat.inactive_count + vmstat.free_count;
               float wired = vmstat.wire_count / total * 100;
               float active = vmstat.active_count / total * 100;
               float inactive = vmstat.inactive_count / total * 100;
               float free = vmstat.free_count / total * 100;
//                NSString *str = [NSString stringWithFormat:@”%d %d %d %d %.2f %.2f %.2f %.2f %.0f %.0f”
//                                                 , vmstat.wire_count, vmstat.active_count, vmstat.inactive_count, vmstat.free_count
//                                                 , wired, active, inactive, free
//                                                 , total, total * pageSize
//                                                 ];

       }










cpu和总线频率:
       int result;
       mib[0] = CTL_HW;
       mib[1] = HW_CPU_FREQ;
       length = sizeof(result);
       if (sysctl(mib, 2, &result, &length, NULL, 0) < 0)
       {
               perror(“getting cpu frequency”);
       }
       printf(“CPU Frequency = %u hz\n”, result);
       
       int result2;
       mib[0] = CTL_HW;
       mib[1] = HW_BUS_FREQ;
       length = sizeof(result2);
       if (sysctl(mib, 2, &result2, &length, NULL, 0) < 0)
       {
               perror(“getting bus frequency”);
       }
       printf(“Bus Frequency = %u hz\n”, result);







网络方面使用的苹果列子文档中的Reachability.h和Reachability.m
外部ip访问http://automation.whatismyip.com/n09230945.asp即可知道。
gethostbyname可知内部局域网ip。







 NetworkStatus netstatus = [reachable currentReachabilityStatus];
   switch (netstatus)
       {
               case NotReachable:
                       // 没有网络连接
                       reachableStatus = NSLocalizedString(@”No Network”, “”);
                       break;
               case ReachableViaWWAN:
                       // 使用3G网络
                       reachableStatus = @”GPRS/3G”;
                       break;
               case ReachableViaWiFi:
                       // 使用WiFi网络
                       reachableStatus = @”WIFI”;
                       break;
   }
这个可知网络类型。







内存大小:

   size_t size = sizeof(int);
   int results;
   int mib[2] = {CTL_HW, HW_PHYSMEM};
   sysctl(mib, 2, &results, &size, NULL, 0);









总磁盘大小:
NSDictionary *fattributes = [[NSFileManager defaultManager] attributesOfFileSystemForPath:NSHomeDirectory() error:nil];
[fattributes objectForKey:NSFileSystemSize];

剩余空间:
[fattributes objectForKey:NSFileSystemFreeSize];








手机号码:
这个也是undocument api
NSString* phoneNumber = CTSettingCopyMyPhoneNumber();











NSArray *getValue(NSString *iosearch)
{
   mach_port_t          masterPort;
   CFTypeID             propID = (CFTypeID) NULL;
   unsigned int         bufSize;
       
   kern_return_t kr = IOMasterPort(MACH_PORT_NULL, &masterPort);
   if (kr != noErr) return nil;
       
   io_registry_entry_t entry = IORegistryGetRootEntry(masterPort);
   if (entry == MACH_PORT_NULL) return nil;
       
   CFTypeRef prop = IORegistryEntrySearchCFProperty(entry, kIODeviceTreePlane, (CFStringRef) iosearch, nil, kIORegistryIterateRecursively);
   if (!prop) return nil;
       
       propID = CFGetTypeID(prop);
   if (!(propID == CFDataGetTypeID())) 
       {
               mach_port_deallocate(mach_task_self(), masterPort);
               CFRelease(prop);
               return nil;
       }
       
   CFDataRef propData = (CFDataRef) prop;
   if (!propData)
       {
               CFRelease(prop);
               return nil;
       }
       
   bufSize = CFDataGetLength(propData);
   if (!bufSize)
       {
               CFRelease(prop);
               return nil;
       }
       
   NSString *p1 = [[[NSString alloc] initWithBytes:CFDataGetBytePtr(propData) length:bufSize encoding:1] autorelease];
   mach_port_deallocate(mach_task_self(), masterPort);
       CFRelease(prop);
   return [p1 componentsSeparatedByString:@”\0″];
}
这个可以用来得到部分数据。



















– (NSString *) imei
{
       NSArray *results = getValue(@”device-imei”);
       if (results) return [results objectAtIndex:0];
       return nil;
}

– (NSString *) serialnumber
{
       NSArray *results = getValue(@”serial-number”);
       if (results) return [results objectAtIndex:0];
       return nil;
}

– (NSString *) backlightlevel
{
       NSArray *results = getValue(@”backlight-level”);
       if (results) return [results objectAtIndex:0];
       return nil;
}

分别得到imei,序列号,背光
