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。
