获取iOS设备信息(内存/电量/容量/型号/IP地址/当前WIFI名称/系統版本)

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[[UIDevicecurrentDevice] batteryLevel];}

2.获取电池状态(UIDeviceBatteryState为枚举类型)

-(UIDeviceBatteryState)getBatteryStauts{return[UIDevicecurrentDevice].batteryState;}

3.获取总内存大小

-(longlong)getTotalMemorySize{return[NSProcessInfoprocessInfo].physicalMemory;}

4.获取当前可用内存

-(longlong)getAvailableMemorySize{vm_statistics_data_tvmStats;mach_msg_type_number_tinfoCount = HOST_VM_INFO_COUNT;kern_return_tkernReturn = host_statistics(mach_host_self(), HOST_VM_INFO, (host_info_t)&vmStats, &infoCount);if(kernReturn != KERN_SUCCESS)    {returnNSNotFound;    }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_ttaskInfo;mach_msg_type_number_tinfoCount = TASK_BASIC_INFO_COUNT;kern_return_tkernReturn = task_info(mach_task_self(),                                        TASK_BASIC_INFO,                                        (task_info_t)&taskInfo,                                        &infoCount);if(kernReturn != KERN_SUCCESS      ) {returnNSNotFound;  }returntaskInfo.resident_size;}

6.获取总磁盘容量

include -(longlong)getTotalDiskSize{structstatfs buf;unsignedlonglongfreeSpace = -1;if(statfs("/var", &buf) >=0)    {        freeSpace = (unsignedlonglong)(buf.f_bsize * buf.f_blocks);    }returnfreeSpace;}

7.获取可用磁盘容量

-(longlong)getAvailableDiskSize{structstatfs buf;unsignedlonglongfreeSpace = -1;if(statfs("/var", &buf) >=0)    {        freeSpace = (unsignedlonglong)(buf.f_bsize * buf.f_bavail);    }returnfreeSpace;}

8.容量转换

-(NSString*)fileSizeToString:(unsignedlonglong)fileSize{NSIntegerKB =1024;NSIntegerMB = KB*KB;NSIntegerGB = MB*KB;if(fileSize <10)  {return@"0 B";    }elseif(fileSize < KB)    {return@"< 1 KB";    }elseif(fileSize < MB)    {return[NSStringstringWithFormat:@"%.1f KB",((CGFloat)fileSize)/KB];    }elseif(fileSize < GB)    {return[NSStringstringWithFormat:@"%.1f MB",((CGFloat)fileSize)/MB];    }else{return[NSStringstringWithFormat:@"%.1f GB",((CGFloat)fileSize)/GB];    }}

8.型号

#import

+ (NSString *)getCurrentDeviceModel:(UIViewController *)controller{intmib[2];size_tlen;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";returnplatform;}

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";structifaddrs *interfaces =NULL;structifaddrs *temp_addr =NULL;intsuccess =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 iPhoneif([[NSStringstringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"en0"]) {// Get NSString from C Stringaddress = [NSStringstringWithUTF8String:inet_ntoa(((structsockaddr_in *)temp_addr->ifa_addr)->sin_addr)];                }            }            temp_addr = temp_addr->ifa_next;        }    }    freeifaddrs(interfaces);returnaddress;}

10.当前手机连接的WIFI名称(SSID)

需要#import

- (NSString*)getWifiName{NSString*wifiName =nil;CFArrayRefwifiInterfaces = CNCopySupportedInterfaces();if(!wifiInterfaces) {returnnil;    }NSArray*interfaces = (__bridgeNSArray*)wifiInterfaces;for(NSString*interfaceNameininterfaces) {CFDictionaryRefdictRef = CNCopyCurrentNetworkInfo((__bridgeCFStringRef)(interfaceName));if(dictRef) {NSDictionary*networkInfo = (__bridgeNSDictionary*)dictRef;            wifiName = [networkInfo objectForKey:(__bridgeNSString*)kCNNetworkInfoKeySSID];CFRelease(dictRef);        }    }CFRelease(wifiInterfaces);returnwifiName;}

11.当前手机系統版本

[[[UIDevice currentDevice] systemVersion] floatValue] ;
