iOS系统获取经纬度

一，获取经纬度
- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
    self.title = @"我在这里";
    
   
    self.tableView.hidden = YES;
    // 定位经纬度
    if ([CLLocationManager locationServicesEnabled]) {
        NSLog(@"开始定位");
        self.myLocationManager = [[CLLocationManager alloc] init];
        self.myLocationManager.delegate = self;
        [self.myLocationManager setDesiredAccuracy:kCLLocationAccuracyNearestTenMeters]; // 定位
        [self.myLocationManager startUpdatingLocation]; // 开始定位
    } else{
        NSLog(@"Location services are not enabled");
    }
}


#pragma mark - CLLocationManager delegate
- (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation
{
    [manager stopUpdatingLocation];
    
    if (self.data == nil) {
        float longitude = newLocation.coordinate.longitude; // 经度
        float latitude = newLocation.coordinate.latitude; // 纬度
        
        NSString *longstring = [NSString stringWithFormat:@"%f", longitude];
        NSString *latitudestring = [NSString stringWithFormat:@"%f", latitude];
        
        NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:latitudestring, @"lat", longstring, @"long", nil];
        [self.sinaweibo requestWithURL:@"place/nearby_timeline.json"
                                params:params
                            httpMethod:@"GET"
                                 block:^(id result) {
                                     [self loadDataFinish:result];
                                 }];
    }
