我們很多時(shí)候做項(xiàng)目的時(shí)候都選用通過(guò)手機(jī)獲取定位，然后傳數(shù)據(jù)給后臺(tái)，這是iOS8根據(jù)經(jīng)緯度顯示地名的demo

    #pragma mark--實(shí)現(xiàn)CLLocationManagerDelegate的代理方法,獲取地理位置(鑌)===========================================================================
    //(1)獲取到位置數(shù)據(jù)，返回的是一個(gè)CLLocation的數(shù)組，一般使用其中的一個(gè)
    - (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
    {
    CLLocation *currLocation = [locations lastObject];
    NSLog(@"經(jīng)度=%f緯度=%f高度=%f", currLocation.coordinate.latitude, currLocation.coordinate.longitude, currLocation.altitude);
    jingduStr =[NSStringstringWithFormat:@"%f", currLocation.coordinate.latitude];
    weiduStr =[NSStringstringWithFormat:@"%f", currLocation.coordinate.longitude];
    NSLog(@"jijijijijij:%@",jingduStr);
    [self change];
    }
    //(2)獲取用戶(hù)位置數(shù)據(jù)失敗的回調(diào)方法，在此通知用戶(hù)
    - (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
    {
    if ([error code] ==kCLErrorDenied)
    {
    //訪問(wèn)被拒絕
    }
    if ([errorcode] == kCLErrorLocationUnknown) {
    //無(wú)法獲取位置信息
    }
    }
