问题描述
我正在获取位置地址的总地址和坐标，但我只需要在谷歌地图上显示的坐标。在iPhone中怎么可能？
I am getting total address and coordinates of the location address but I need only coordinates to show on the google map. How is it possible in iPhone?
- (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
推荐答案
试试这个
- (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;
}
