MKMapView定位地址
需要在MKMapView中加载一个地址，用了下面的代码：
CLLocationCoordinate2D location = [self getLocationFromAddressString:@"321 Iowa St, Fallbrook, CA 92028, United States US"];
MKCoordinateRegion region;
MKCoordinateSpan span;
span.latitudeDelta = 0.05;
span.longitudeDelta = 0.05;
region.span = span;
region.center = location;
[mapView setRegion:region animated:YES];
[mapView regionThatFits:region];接下来的代码是用了获取地址的定位：
-(CLLocationCoordinate2D) getLocationFromAddressString:(NSString*) addressStr
{
NSString *urlStr = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv",
[addressStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSError *error = nil;
NSString *locationStr = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlStr] encoding:NSUTF8StringEncoding error:&error];
NSArray *items = [locationStr componentsSeparatedByString:@","];
double lat = 0.0;
double lon = 0.0;
if([items count] >= 4 && [[items objectAtIndex:0] isEqualToString:@"200"]) {
lat = [[items objectAtIndex:2] doubleValue];
lon = [[items objectAtIndex:3] doubleValue];
}
else {
NSLog(@"Address, %@ not found: Error %@",addressStr, [items objectAtIndex:0]);
}
CLLocationCoordinate2D location;
location.latitude = lat;
location.longitude = lon;
return location;
}但是返回结果：
`
Address, 321 Iowa St, Fallbrook, CA 92028, United States US not found: Error 610
`
这是为什么？

试试：
- (CLLocationCoordinate2D) geoCodeUsingAddress:(NSString *)address { double latitude = 0.0; double longitude = 0.0; NSString *esc_addr = [address stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSString *req = [NSString stringWithFormat:@"http://maps.google.com/maps/api/geocode/json?sensor=false&address=%@", esc_addr]; NSDictionary *googleResponse = [[NSString stringWithContentsOfURL: [NSURL URLWithString: req] encoding: NSUTF8StringEncoding error: NULL] JSONValue]; NSDictionary *resultsDict = [googleResponse valueForKey: @"results"]; // get the results dictionary NSDictionary *geometryDict = [resultsDict valueForKey: @"geometry"]; // geometry dictionary within the results dictionary NSDictionary *locationDict = [geometryDict valueForKey: @"location"]; // location dictionary within the geometry dictionary NSArray *latArray = [locationDict valueForKey: @"lat"]; NSString *latString = [latArray lastObject]; // (one element) array entries provided by the json parser NSArray *lngArray = [locationDict valueForKey: @"lng"]; NSString *lngString = [lngArray lastObject]; // (one element) array entries provided by the json parser CLLocationCoordinate2D location; location.latitude = [latString doubleValue];// latitude; location.longitude = [lngString doubleValue]; //longitude; return location; }可能会在
