Iphone Placemark未提供邮政编码以了解天气信息

我想从当前位置了解天气情况

为此，我将代码用作

-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
    [self.locationManager stopUpdatingLocation];

    self.location = newLocation;
//    NSLog(@"lat long = %f,%f",self.location.coordinate.latitude,self.location.coordinate.longitude);

    // Geocode coordinate (normally we'd use location.coordinate here instead of coord).
    // This will get us something we can query Google's Weather API with

    if (boolCurrentlyWorking == NO) {

        CLGeocoder* reverseGeocoder = [[CLGeocoder alloc] init];
        if(reverseGeocoder)
        {
            [reverseGeocoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *placemarks, NSError *error) {
                CLPlacemark* placemark = [placemarks objectAtIndex:0];
                if (placemark) {
                    //Using blocks, get zip code
                    NSString *zipCode = [placemark.addressDictionary objectForKey:(NSString*)kABPersonAddressZIPKey];
                    NSLog(@"placemark : %@ zipcode : %@",placemark.addressDictionary,zipCode);
                }
            }];

        }else{
            MKReverseGeocoder *geocoder = [[MKReverseGeocoder alloc] initWithCoordinate:self.location.coordinate];
            geocoder.delegate = self;
            [geocoder start];
        }
     }

    boolCurrentlyWorking = YES;
}

我这里没有邮政编码

还发现，这种didupdate位置方法已被弃用，新方法正在使用中

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    CLLocation *location = [locations lastObject];
    CLLocation *newlocation = location;
    NSLog(@"location : %@",location);
    CLGeocoder* reverseGeocoder = [[CLGeocoder alloc] init];
    if(reverseGeocoder)
    {
        [reverseGeocoder reverseGeocodeLocation:newlocation completionHandler:^(NSArray *placemarks, NSError *error) {
            for(CLPlacemark *placemark in placemarks)
            {
                NSLog(@"plcaemark desc : %@",[placemark description]);
            }
        }];
    }
}

但它也不包含zipcode

我得到了这个描述

{
    Country = India;
    CountryCode = IN;
    FormattedAddressLines =     (
        NH8C,
        Gujarat,
        India
    );
    Name = NH8C;
    State = Gujarat;
    Street = NH8C;
    Thoroughfare = NH8C;
}

---

有没有像它不提供zipcode信息，我们必须建立它？如果是，那怎么办？

首先，我们得不到印度的邮政编码

谷歌API也已经停止工作

我使用YahooAPI来了解天气

下面是可能对某人有所帮助的代码

-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
    [self.locationManager stopUpdatingLocation];

    self.location = newLocation;



        NSString *linkForWoeid = [NSString stringWithFormat:@" http://where.yahooapis.com/geocode?location=%f,%f&flags=J&gflags=R&appid=zHgnBS4m",self.location.coordinate.latitude,self.location.coordinate.longitude];
        NSURL *woeidURL = [NSURL URLWithString:linkForWoeid];
        NSData *WoeidData = [NSData dataWithContentsOfURL:woeidURL];
        if (WoeidData != NULL)
        {
            NSError *woeiderr = nil;
            NSDictionary *aDicWOEIDResp = [NSJSONSerialization JSONObjectWithData:WoeidData options:NSJSONReadingMutableContainers error:&woeiderr];
            NSDictionary *aDictWOEID = [[[[aDicWOEIDResp objectForKey:@"ResultSet"]objectForKey:@"Results"]objectAtIndex:0]objectForKey:@"woeid"];

            NSString *address=[NSString stringWithFormat:@"http://weather.yahooapis.com/forecastrss?w=%@",aDictWOEID];
            ICB_WeatherConditions *icbWeather = [[ICB_WeatherConditions alloc] initWithQuery:address];

对于（int i=0；我是否尝试过模拟您已经模拟过的位置以外的其他位置？我自己尝试过，我没有从地理编码器处收到印度许多地方的邮政编码。是的，印度没有zipcode或邮政编码
