Question

我根据经度和纬度值得到了当前位置然后我还使用Annotation在谷歌地图上获得了多个位置现在我想根据邮政编码获取经度和纬度值我不知道如何根据邮政编码获得经度和纬度值

Answer 1

这是调用google map api进行地理编码的方法，如果您通过Zipcode / Postal代码，则会得到结果

-(void)ViewDidLoad
{ 

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://maps.google.com/maps/api/geocode/json?sensor=false&address=%@",yourzipcodetext/PostalcodeText.text]]];

[request setHTTPMethod:@"POST"];

NSError *err;
NSURLResponse *response;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
NSString *resSrt = [[NSString alloc]initWithData:responseData encoding:NSASCIIStringEncoding];

NSLog(@"got response==%@", resSrt);

NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:nil];

NSString *lataddr=[[[[[dict objectForKey:@"results"] objectAtIndex:0]objectForKey:@"geometry"]objectForKey:@"location"]objectForKey:@"lat"];

NSString *longaddr=[[[[[dict objectForKey:@"results"] objectAtIndex:0]objectForKey:@"geometry"]objectForKey:@"location"]objectForKey:@"lng"];


NSLog(@"The resof latitude=%@", lataddr);

NSLog(@"The resof longitude=%@", longaddr);


}

CLGeocoder *geoCoder = [[CLGeocoder alloc] init];
    [geoCoder geocodeAddressString:@"ZIP CODE HERE" completionHandler:^(NSArray *placemarks, NSError *error) {
        CLPlacemark *placemark = [placemarks objectAtIndex:0];
        CLLocation *location = placemark.location;
        CLLocationCoordinate2D coordinate = location.coordinate;
        NSLog(@"Latitude %f", coordinate.latitude);
        NSLog(@"Longitude %f", coordinate.longitude);
    }];

就像这样简单：

CLGeocoder *geoCoder = [[CLGeocoder alloc] init];
    [geoCoder geocodeAddressString:@"ZIP CODE HERE" completionHandler:^(NSArray *placemarks, NSError *error) {
        CLPlacemark *placemark = [placemarks objectAtIndex:0];
        CLLocation *location = placemark.location;
        CLLocationCoordinate2D coordinate = location.coordinate;
        NSLog(@"Latitude %f", coordinate.latitude);
        NSLog(@"Longitude %f", coordinate.longitude);
    }];

Apple在forward geocoding上发布了可以帮助您的好文档。

使用IOS中的Geocoder类，基于zip获取经度和纬度
