获取iOS设备信息(内存/电量/容量/型号/IP地址/当前WIFI名称)

最近工作上需要获取设备的一些信息,整理了一下,方便大家。 1 获取电池电量(一般用百分数表示,大家自行处理就好) -(CGFloat)getBattery

最近工作上需要获取设备的一些信息,整理了一下,方便大家。

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 [[UIDevice currentDevice] batteryLevel];}

2.获取电池状态(UIDeviceBatteryState为枚举类型)

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

3.获取总内存大小

-(long long)getTotalMemorySize{ return [NSProcessInfo processInfo].physicalMemory;}

4.获取当前可用内存

-(long long)getAvailableMemorySize{ 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));}

5.获取已使用内存

- (double)getUsedMemory{ 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;}

6.获取总磁盘容量

include  -(long long)getTotalDiskSize{ 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;}

7.获取可用磁盘容量

-(long long)getAvailableDiskSize{ struct statfs buf; unsigned long long freeSpace = -1; if (statfs("/var", &buf) >= 0) { freeSpace = (unsigned long long)(buf.f_bsize * buf.f_bavail); } return freeSpace;}

8.容量转换

-(NSString *)fileSizeToString:(unsigned long long)fileSize{ NSInteger KB = 1024; NSInteger MB = KB*KB; NSInteger GB = MB*KB; if (fileSize < 10) { 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]; }}

8.型号

#import <sys sysctl="" h=""></sys>

+ (NSString *)getCurrentDeviceModel:(UIViewController *)controller{ int mib[2]; size_t len; 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"; return platform;}

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 #import

- (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"]) { // 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;}

10.当前手机连接的WIFI名称(SSID)

需要 #import

- (NSString *)getWifiName{ NSString *wifiName = nil; CFArrayRef wifiInterfaces = CNCopySupportedInterfaces(); if (!wifiInterfaces) { return nil; } NSArray *interfaces = (__bridge NSArray *)wifiInterfaces; for (NSString *interfaceName in interfaces) { CFDictionaryRef dictRef = CNCopyCurrentNetworkInfo((__bridge CFStringRef)(interfaceName)); if (dictRef) { NSDictionary *networkInfo = (__bridge NSDictionary *)dictRef; wifiName = [networkInfo objectForKey:(__bridge NSString *)kCNNetworkInfoKeySSID]; CFRelease(dictRef); } } CFRelease(wifiInterfaces); return wifiName;}
