首先导入四个头文件
#include <sys/types.h> #include <sys/sysctl.h> #include <ifaddrs.h> #include <arpa/inet.h>
获取设备型号：
+ (NSString *) platform { size_t size; sysctlbyname("hw.machine", NULL, &size, NULL, 0); char *machine = malloc(size); sysctlbyname("hw.machine", machine, &size, NULL, 0); NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding]; free(machine); return platform; } + (NSString *)getReturnPlat:(NSString *)platform { // http://theiphonewiki.com/wiki/Models 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:@"iPhone3,3"]) return @"iPhone 4 (CDMA)"; if ([platform isEqualToString:@"iPhone4,1"]) return @"iPhone 4S"; if ([platform isEqualToString:@"iPhone5,1"]) return @"iPhone 5"; if ([platform isEqualToString:@"iPhone5,2"]) return @"iPhone 5 (GSM+CDMA)"; if ([platform isEqualToString:@"iPhone5,3"]) return @"iPhone 5C"; if ([platform isEqualToString:@"iPhone5,4"]) return @"iPhone 5C (Global)"; if ([platform isEqualToString:@"iPhone6,1"]) return @"iPhone 5S"; if ([platform isEqualToString:@"iPhone6,2"]) return @"iPhone 5S (Global)"; if ([platform isEqualToString:@"iPhone7,2"]) return @"iPhone 6"; if ([platform isEqualToString:@"iPhone7,1"]) return @"iPhone 6 Plus"; 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 (1 Gen)"; if ([platform isEqualToString:@"iPod2,1"]) return @"iPod Touch (2 Gen)"; if ([platform isEqualToString:@"iPod3,1"]) return @"iPod Touch (3 Gen)"; if ([platform isEqualToString:@"iPod4,1"]) return @"iPod Touch (4 Gen)"; if ([platform isEqualToString:@"iPod5,1"]) return @"iPod Touch (5 Gen)"; if ([platform isEqualToString:@"iPad1,1"]) return @"iPad"; if ([platform isEqualToString:@"iPad1,2"]) return @"iPad 3G"; if ([platform isEqualToString:@"iPad2,1"]) return @"iPad 2 (WiFi)"; if ([platform isEqualToString:@"iPad2,2"]) return @"iPad 2"; if ([platform isEqualToString:@"iPad2,3"]) return @"iPad 2 (CDMA)"; if ([platform isEqualToString:@"iPad2,4"]) return @"iPad 2"; if ([platform isEqualToString:@"iPad2,5"]) return @"iPad Mini (WiFi)"; if ([platform isEqualToString:@"iPad2,6"]) return @"iPad Mini"; if ([platform isEqualToString:@"iPad2,7"]) return @"iPad Mini (GSM+CDMA)"; if ([platform isEqualToString:@"iPad3,1"]) return @"iPad 3 (WiFi)"; if ([platform isEqualToString:@"iPad3,2"]) return @"iPad 3 (GSM+CDMA)"; if ([platform isEqualToString:@"iPad3,3"]) return @"iPad 3"; if ([platform isEqualToString:@"iPad3,4"]) return @"iPad 4 (WiFi)"; if ([platform isEqualToString:@"iPad3,5"]) return @"iPad 4"; if ([platform isEqualToString:@"iPad3,6"]) return @"iPad 4 (GSM+CDMA)"; if ([platform isEqualToString:@"i386"]) return @"Simulator"; if ([platform isEqualToString:@"x86_64"]) return @"Simulator"; return platform; } + (NSString *) getStandardPlat { return [self getReturnPlat:[self platform]]; }
获取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"] || [[NSString stringWithUTF8String:temp_addr->ifa_name] isEqualToString:@"pdp_ip0"] ) { // 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); NSLog(@"手机的IP是：%@", address); return address; }
