在進(jìn)行iOS開(kāi)發(fā)過(guò)程中，我們有時(shí)候需要獲取設(shè)備的一些信息。下面整理了一些常用的獲取設(shè)備信息的方法。
1.獲取系統(tǒng)版本號(hào)
[[UIDevice currentDevice] systemVersion];
2. 獲取設(shè)備名稱(chēng)
[[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(chēng)
- 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(chēng)
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，這個(gè)是蘋(píng)果官方的設(shè)備類(lèi)型說(shuō)明。
//需要導(dǎo)入的包
#import <sys/utsname.h>
//獲取設(shè)備型號(hào)
- (NSString *)getDeviceModelName {
struct utsname systemInfo;
uname(&systemInfo);
NSString *deviceModel = [NSString stringWithCString:systemInfo.machine
encoding:NSUTF8StringEncoding];
NSString *name = [self getVersionName:deviceModel];
return name;
}
