在進(jìn)行iOS開發(fā)過程中斩例，我們有時(shí)候需要獲取設(shè)備的一些信息励七。下面整理了一些常用的獲取設(shè)備信息的方法扔字。

1.獲取系統(tǒng)版本號(hào)

[[UIDevice currentDevice] systemVersion];

2. 獲取設(shè)備名稱

[[UIDevice currentDevice] name];

3.獲取APP版本

NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];
NSString *appVersion = [infoDic objectForKey:@"CFBundleShortVersionString"];

4.獲取運(yùn)營(yíng)商名稱

• 需要先導(dǎo)入頭文件

#import <CoreTelephony/CTCarrier.h>  
#import <CoreTelephony/CTTelephonyNetworkInfo.h>  

• 獲取運(yùn)營(yíng)商名稱

CTTelephonyNetworkInfo *info = [[CTTelephonyNetworkInfo alloc] init];
CTCarrier *carrier = [info subscriberCellularProvider];
NSString *carrierName = [NSString stringWithFormat:@"%@",[carrier carrierName]];

5.獲取IP地址

IP地址分為內(nèi)網(wǎng)和公網(wǎng)的IP地址

• 獲取內(nèi)網(wǎng)IP

// 需要導(dǎo)入的包
#import <ifaddrs.h>
#import <arpa/inet.h>
#import <net/if.h>

// 宏定義
#define IOS_CELLULAR @"pdp_ip0"
#define IOS_WIFI @"en0"
#define IOS_VPN @"utun0"
#define IP_ADDR_IPv4 @"ipv4"
#define IP_ADDR_IPv6 @"ipv6"

- (NSString *)getIPAddress {
    NSArray *searchArray = @[ 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 ];
    NSDictionary *addresses = [self getAddresses];
    __block NSString *address;
    [searchArray enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL 
      * _Nonnull stop) {
        address = addresses[obj];
        NSLog(@"key = %@ ; object = %@",obj,addresses[obj]);
        if([self isValidateIP:address]) *stop = YES;
    }];
    return address ? address : @"0.0.0.0";
}

- (BOOL)isValidateIP:(NSString *)ipAddress {
    if (ipAddress.length == 0) {
        return NO;
    }
    NSString *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])\\."
    "([01]?\\d\\d?|2[0-4]\\d|25[0-5])$";
    NSError *error;
    NSRegularExpression *regex = 
    [NSRegularExpressionregularExpressionWithPattern:urlRegEx options:0 error:&error];
    if (regex != nil) {
        NSTextCheckingResult *firstMatch = [regex firstMatchInString:ipAddress 
            options:0 range:NSMakeRange(0, [ipAddress length])];
        if (firstMatch) {
            NSRange resultRange = [firstMatch rangeAtIndex:0];
            NSString *result = [ipAddress substringWithRange:resultRange];
            NSLog(@"result = %@",result);
            return YES;
        }
    }
    return NO;
}

- (NSDictionary *)getAddresses {
    NSMutableDictionary *addresses = [NSMutableDictionary dictionaryWithCapacity:8];
    struct ifaddrs *interfaces;
    if (!getifaddrs(&interfaces)) {
        struct ifaddrs *interface;
        for (interface=interfaces; interface; interface=interface->ifa_next) {
            if (!(interface->ifa_flags & IFF_UP)) {
                continue;
            }
            const struct sockaddr_in *addr = (const struct sockaddr_in*)interface-
              >ifa_addr;
            char addrBuf[MAX(INET_ADDRSTRLEN, INET6_ADDRSTRLEN)];
            if (addr && (addr->sin_family==AF_INET || addr->sin_family==AF_INET6)) {
                NSString *name = [NSString stringWithUTF8String:interface-
                >ifa_name];
                NSString *type;
                if (addr->sin_family == AF_INET) {
                  if (inet_ntop(AF_INET, &addr->sin_addr, addrBuf, INET_ADDRSTRLEN)) {
                        type = IP_ADDR_IPv4;
                    }
                } else {
                    const struct sockaddr_in6 *addr6 = (const struct 
                        sockaddr_in6*)interface->ifa_addr;
                    if (inet_ntop(AF_INET6, &addr6->sin6_addr, addrBuf, 
                        INET6_ADDRSTRLEN)) {
                        type = IP_ADDR_IPv6;
                    }
                }
                if (type) {
                    NSString *key = [NSString stringWithFormat:@"%@/%@",name,type];
                    addresses[key] = [NSString stringWithUTF8String:addrBuf];
                }
            }
        }
        freeifaddrs(interfaces);
    }
    return [addresses count] ? addresses : nil;
}

• 獲取公網(wǎng)IP

NSURL *ipURL = [NSURL URLWithString:@"http://ip.taobao.com/service/getIpInfo.php?
    ip=myip"];
NSData *data = [NSData dataWithContentsOfURL:ipURL];
NSDictionary *ipDic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
NSString *ipStr = nil;
if (ipDic && [ipDic[@"code"] integerValue]== 0) {
    ipStr = ipDic[@"data"][@"ip"];
}
return (ipStr ? ipStr : @"");

6.獲取設(shè)備的型號(hào)

需要獲取的型號(hào)格式如：iPhone 6s Plus
參考： https://www.theiphonewiki.com/wiki/Models菩咨，這個(gè)是蘋果官方的設(shè)備類型說明丢烘。

//需要導(dǎo)入的包
#import <sys/utsname.h>

//獲取設(shè)備型號(hào)

    struct utsname systemInfo;
    uname(&systemInfo);

    NSString *name = [self getVersionName:deviceModel];
    return name;
