最近公司app需要添加获取用户信息的新功能。将这些 功能写下来,以备不时之需。

获取手机uuid

+ (String *)getUUID 
{  
    return [[[UIDevice currentDevice] identifierForVendor] UUIDString];

}

获取操作系统版本

+ (float)getIOSVersion  
{  
    return [[[UIDevice currentDevice] systemVersion] floatValue];  
}  

获取位置信息

设置请求访问信息

<key>NSLocationWhenInUseUsageDescription</key>
<string>when</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>always</string>

完整代码

#import <CoreLocation/CoreLocation.h>
@interface MainViewController ()<CLLocationManagerDelegate>
{
    CLLocationManager *locationmanager;//定位服务
    NSString *currentCity;//当前城市
    NSString *strlatitude;//经度
    NSString *strlongitude;//纬度
}
@end

@implementation MainViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [self startLocation];
    // Do any additional setup after loading the view.
}

//开始定位
- (void)startLocation {
    if ([CLLocationManager locationServicesEnabled]) {
        //        CLog(@"--------开始定位");
        self.locationManager = [[CLLocationManager alloc]init];
        self.locationManager.delegate = self;
        //控制定位精度,越高耗电量越大
        self.locationManager.desiredAccuracy = kCLLocationAccuracyKilometer;
        // 总是授权
        [self.locationManager requestAlwaysAuthorization];
        self.locationManager.distanceFilter = 10.0f;
        [self.locationManager requestAlwaysAuthorization];
        [self.locationManager startUpdatingLocation];
    }
}

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
    if ([error code] == kCLErrorDenied) {
        CLog(@"访问被拒绝");
    }
    if ([error code] == kCLErrorLocationUnknown) {
        CLog(@"无法获取位置信息");
    }
}

//定位代理经纬度回调
#pragma mark 定位成功后则执行此代理方法
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations
{
    [locationmanager stopUpdatingHeading];
    //旧址
    CLLocation *currentLocation = [locations lastObject];
    CLGeocoder *geoCoder = [[CLGeocoder alloc]init];
    //打印当前的经度与纬度
    NSLog(@"%f,%f",currentLocation.coordinate.latitude,currentLocation.coordinate.longitude);

    //反地理编码
    [geoCoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray<CLPlacemark *> * _Nullable placemarks, NSError * _Nullable error) {
        if (placemarks.count > 0) {
            CLPlacemark *placeMark = placemarks[0];
            currentCity = placeMark.locality;
            if (!currentCity) {
                currentCity = @"无法定位当前城市";
            }

            /*看需求定义一个全局变量来接收赋值*/
            NSLog(@"----%@",placeMark.country);//当前国家
            NSLog(@"%@",currentCity);//当前的城市
//            NSLog(@"%@",placeMark.subLocality);//当前的位置
//            NSLog(@"%@",placeMark.thoroughfare);//当前街道
//            NSLog(@"%@",placeMark.name);//具体地址

        }
    }];

}

获取公网ip

+(NSString *)deviceWANIPAddress  
{  
    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) { //获取成功  
        ipStr = ipDic[@"data"][@"ip"];  
    }  
    return (ipStr ? ipStr : @"");  
}  

获取当前时间

获取当前时间

- (NSString *)currentDateStr{
    NSDate *currentDate = [NSDate date];//获取当前时间,日期
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];// 创建一个时间格式化对象
    [dateFormatter setDateFormat:@"YYYY/MM/dd hh:mm:ss SS "];//设定时间格式,这里可以设置成自己需要的格式
    NSString *dateString = [dateFormatter stringFromDate:currentDate];//将时间转化成字符串
    return dateString;
}

获取当前时间戳

//获取当前时间戳
- (NSString *)currentTimeStr{
    NSDate* date = [NSDate dateWithTimeIntervalSinceNow:0];//获取当前时间0秒后的时间
    NSTimeInterval time=[date timeIntervalSince1970]*1000;// *1000 是精确到毫秒,不乘就是精确到秒
    NSString *timeString = [NSString stringWithFormat:@"%.0f", time];
    return timeString;
}

获取移动端ip

需要的头文件

//IP地址需求库  
#import <sys/socket.h>  
#import <sys/sockio.h>  
#import <sys/ioctl.h>  
#import <net/if.h>  
#import <arpa/inet.h>  

获取ip地址

//获取设备IP地址  
+ (NSString *)getDeviceIPAddresses  
{  
    int sockfd = socket(AF_INET,SOCK_DGRAM, 0);  
    // if (sockfd <</span> 0) return nil; //这句报错,由于转载的,不太懂,注释掉无影响,懂的大神欢迎指导  
    NSMutableArray *ips = [NSMutableArray array];  

    int BUFFERSIZE =4096;  

    struct ifconf ifc;  

    char buffer[BUFFERSIZE], *ptr, lastname[IFNAMSIZ], *cptr;  

    struct ifreq *ifr, ifrcopy;  

    ifc.ifc_len = BUFFERSIZE;  

    ifc.ifc_buf = buffer;  

    if (ioctl(sockfd,SIOCGIFCONF, &ifc) >= 0){  

        for (ptr = buffer; ptr < buffer + ifc.ifc_len; ){  

            ifr = (struct ifreq *)ptr;  

            int len =sizeof(struct sockaddr);  

            if (ifr->ifr_addr.sa_len > len) {  
                len = ifr->ifr_addr.sa_len;  
            }  

            ptr += sizeof(ifr->ifr_name) + len;  

            if (ifr->ifr_addr.sa_family !=AF_INET) continue;  

            if ((cptr = (charchar *)strchr(ifr->ifr_name,':')) != NULL) *cptr =0;  

            if (strncmp(lastname, ifr->ifr_name,IFNAMSIZ) == 0)continue;  

            memcpy(lastname, ifr->ifr_name,IFNAMSIZ);  

            ifrcopy = *ifr;  

            ioctl(sockfd,SIOCGIFFLAGS, &ifrcopy);  

            if ((ifrcopy.ifr_flags &IFF_UP) == 0)continue;  

            NSString *ip = [NSString stringWithFormat:@"%s",inet_ntoa(((struct sockaddr_in *)&ifr->ifr_addr)->sin_addr)];  
            [ips addObject:ip];  
        }  
    }  
    close(sockfd);  

    NSString *deviceIP =@"";  

    for (int i=0; i < ips.count; i++){  
        if (ips.count >0){  
            deviceIP = [NSString stringWithFormat:@"%@",ips.lastObject];  
        }  
    }  

    return deviceIP;  
}  

以上方法没有进行测试,使用时需要自己测试。

最后给出自己的个人博客
