如何从内容的总地址获得坐标？

我得到的位置地址的总地址和坐标，但我只需要坐标显示在谷歌地图上。 iPhone怎么可能？

- (void)geocode { [SVGeocoder geocode:addressField.text completion:^(NSArray *placemarks, NSError *error) { UIAlertView *alertView; if(!error && placemarks) { SVPlacemark *placemark = [placemarks objectAtIndex:0]; NSLog(@"%@",placemarks); alertView = [[UIAlertView alloc] initWithTitle:@"Placemark Found!" message:[placemark description] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; } else { alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:[error description] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; } [alertView show]; [alertView release]; }]; 

地理编码的响应

\ n国家=印度; \ n国家代码= IN; \ n国家=“安得拉邦”; \ n}; \ n坐标= {\ n纬度= \ n \ “17.05239 \”; \ n经度= \“79.26718 \”; \ n}; \ n
formattedAddress =“纳尔贡达，印度安得拉邦”; \ n}“

尝试这个

 - (CLLocationCoordinate2D) geoCodeUsingAddress:(NSString *)address { double latitude = 0, longitude = 0; NSString *esc_addr = [address stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSString *req = [NSString stringWithFormat:@"http://maps.google.com/maps/api/geocode/json?sensor=false&address=%@", esc_addr]; NSString *result = [NSString stringWithContentsOfURL:[NSURL URLWithString:req] encoding:NSUTF8StringEncoding error:NULL]; if (result) { NSScanner *scanner = [NSScanner scannerWithString:result]; if ([scanner scanUpToString:@"\"lat\":" intoString:nil] && [scanner scanString:@"\"lat\":" intoString:nil]) { [scanner scanDouble:&latitude]; if ([scanner scanUpToString:@"\"lng\":" intoString:nil] && [scanner scanString:@"\"lng\":" intoString:nil]) { [scanner scanDouble:&longitude]; } } } CLLocationCoordinate2D center; center.latitude = latitude; center.longitude = longitude; return center; }
