iOS常用系统信息获取方法

一、手机电量获取，方法二需要导入头文件#import<objc/runtime.h>

方法一、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];

 }

方法二、

 - (int)getCurrentBatteryLevel

 {

     UIApplication *app = [UIApplication sharedApplication];

     if (app.applicationState == UIApplicationStateActive||

         app.applicationState==UIApplicationStateInactive)

     {

         Ivar ivar=  class_getInstanceVariable([app class],"_statusBar");

         id status  = object_getIvar(app, ivar);

         for (id aview in [status subviews])

         {

             int batteryLevel = ;

             for (id bview in [aview subviews])

             {

                 if ([NSStringFromClass([bview class]) caseInsensitiveCompare:@"UIStatusBarBatteryItemView"]

                     == NSOrderedSame&&[[[UIDevice currentDevice] systemVersion] floatValue] >=6.0)

                 {

                     Ivar ivar = class_getInstanceVariable([bview class],"_capacity");

                     if(ivar)

                     {

                         batteryLevel = ((int (*)(id, Ivar))object_getIvar)(bview, ivar);

                         //这种方式也可以

                         /*ptrdiff_t offset = ivar_getOffset(ivar);

                          unsigned char *stuffBytes = (unsigned char *)(__bridge void *)bview;

                          batteryLevel = * ((int *)(stuffBytes + offset));*/

                         if (batteryLevel >  && batteryLevel <= ){

                             return batteryLevel;

                         }

                         else{

                             return ;

                         }

                     }

                 }

             }

         }

     }

     return ;

 }

二、获取手机电池状态（UIDeviceBatteryState为枚举类型）

 //     UIDeviceBatteryStateUnknown：无法取得充电状态情况

 //     UIDeviceBatteryStateUnplugged：非充电状态

 //     UIDeviceBatteryStateCharging：充电状态

 //     UIDeviceBatteryStateFull：充满状态（连接充电器充满状态）

 -(UIDeviceBatteryState)getBatteryStauts

 {

     UIDevice *device = [UIDevice currentDevice];

     device.batteryMonitoringEnabled = YES;

     return device.batteryState;

 }

三、获取手机总运行内存大小

 //3.获取总内存大小

 -(NSString *)getTotalMemorySize

 {

     return [self fileSizeToString:[NSProcessInfo processInfo].physicalMemory];

 }

 -(NSString *)fileSizeToString:(unsigned long long)fileSize

 {

     NSInteger KB = ;

     NSInteger MB = KB*KB;

     NSInteger GB = MB*KB;

     if (fileSize < )  {

         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];

     }

 }

四、获取当前剩余内存和已用内存，需要添加头文件#import <sys/sysctl.h> 和#import <mach/mach.h>

 // 获取当前设备可用内存(单位：MB）

 - (double)availableMemory

 {

   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) / 1024.0) / 1024.0;

 }  

 // 获取当前任务所占用的内存（单位：MB）

 - (double)usedMemory

 {

   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 / 1024.0 / 1024.0;

 }

五、获取手机型号，需要添加头文件#import<sys/utsname.h>

 + (NSString *)getCurrentiPhoneType

 {

     struct utsname systemInfo;

     uname(&systemInfo);

     NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSASCIIStringEncoding];

     if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 2G";

     if ([platform isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";

     if ([platform isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS";

     if ([platform isEqualToString:@"iPhone3,1"]) return @"iPhone 4";

     if ([platform isEqualToString:@"iPhone3,2"]) return @"iPhone 4";

     if([platform isEqualToString:@"iPhone10,5"]) return@"iPhone 8 Plus";

     if([platform isEqualToString:@"iPhone10,3"]) return@"iPhone X";

     if([platform isEqualToString:@"iPhone10,6"]) return@"iPhone X";

     if([platform isEqualToString:@"iPod1,1"]) return@"iPod Touch 1G";

     if([platform isEqualToString:@"iPod2,1"]) return@"iPod Touch 2G";

     if([platform isEqualToString:@"iPod3,1"]) return@"iPod Touch 3G";

     if([platform isEqualToString:@"iPod4,1"]) return@"iPod Touch 4G";

     if([platform isEqualToString:@"iPad2,1"]) return@"iPad 2";

     if([platform isEqualToString:@"iPad2,2"]) return@"iPad 2";

     if([platform isEqualToString:@"iPad2,3"]) return@"iPad 2";

     if([platform isEqualToString:@"iPad2,4"]) return@"iPad 2";

     if([platform isEqualToString:@"iPad2,5"]) return@"iPad Mini 1G";

     if([platform isEqualToString:@"iPad2,6"]) return@"iPad Mini 1G";

     if([platform isEqualToString:@"iPad2,7"]) return@"iPad Mini 1G";

     if([platform isEqualToString:@"iPad5,2"]) return@"iPad Mini 4";

     if([platform isEqualToString:@"iPad5,3"]) return@"iPad Air 2";

     if([platform isEqualToString:@"iPad5,4"]) return@"iPad Air 2";

     if([platform isEqualToString:@"iPad6,3"]) return@"iPad Pro 9.7";

     if([platform isEqualToString:@"iPad6,4"]) return@"iPad Pro 9.7";

     if([platform isEqualToString:@"iPad6,7"]) return@"iPad Pro 12.9";

     if([platform isEqualToString:@"iPad6,8"]) return@"iPad Pro 12.9";

     if([platform isEqualToString:@"i386"]) return@"iPhone Simulator";

     if([platform isEqualToString:@"x86_64"]) return@"iPhone Simulator";

     return platform;

 }

六、IP地址获取，只适用于WiFi网络需要添加以下头文件和宏定义

 #import <ifaddrs.h>  //ip

 #import <arpa/inet.h>

 #import <net/if.h>

 #import <__clang_cuda_runtime_wrapper.h>

 #define IOS_CELLULAR    @"pdp_ip0"

 #define IOS_WIFI        @"en0"

 #define IOS_VPN         @"utun0"

 #define IP_ADDR_IPv4    @"ipv4"

 #define IP_ADDR_IPv6    @"ipv6"

方法一、

 - (NSString *)deviceIPAdress {

     NSString *address = @"an error occurred when obtaining ip address";

     struct ifaddrs *interfaces = NULL;

     struct ifaddrs *temp_addr = NULL;

     int success = ;

     success = getifaddrs(&interfaces);

     if (success == )  // 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;

 }

方法二、获取设备当前网络IP地址 (WiFi 手机流量通用)

 //获取IPV4地址

 + (NSString *)getDevicesIPV4Address

 {

     return [self getDevicesIPAddress:YES];

 }

 //获取IPV6地址

 + (NSString *)getDevicesIPV6Address

 {

     return [self getDevicesIPAddress:NO];

 }

 + (NSString *)getDevicesIPAddress:(BOOL)preferIPv4

 {

     NSArray *searchArray = preferIPv4 ? @[IOS_VPN @"/" IP_ADDR_IPv4, IOS_VPN @"/" IP_ADDR_IPv6, IOS_WIFI @"/" IP_ADDR_IPv4, IOS_WIFI @"/" IP_ADDR_IPv6, IOS_CELLULAR @"/" IP_ADDR_IPv4, IOS_CELLULAR @"/" IP_ADDR_IPv6 ] :  @[ IOS_VPN @"/" IP_ADDR_IPv6, IOS_VPN @"/" IP_ADDR_IPv4, IOS_WIFI @"/" IP_ADDR_IPv6, IOS_WIFI @"/" IP_ADDR_IPv4, IOS_CELLULAR @"/" IP_ADDR_IPv6, IOS_CELLULAR @"/" IP_ADDR_IPv4 ] ;

     NSDictionary *addresses = [self getIPAddresses];

     __block NSString *address;

     [searchArray enumerateObjectsUsingBlock:^(NSString *key, NSUInteger idx, BOOL *stop)

      {

          address = addresses[key];

          //筛选出IP地址格式

          if([self isValidatIP:address isIpV4:preferIPv4]) *stop = YES;

      } ];

     return address ? address : @"0.0.0.0";

 }

 + (BOOL)isValidatIP:(NSString *)ipAddress isIpV4:(BOOL)ipv4 {

     if (ipAddress.length == ) {

         return NO;

     }

     NSString *urlRegEx;

     if (ipv4)

     {

         urlRegEx = @"^([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\."

         "([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\."

         "([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\."

     }

     else
