I have an array of coordinates that I step through with a for loop. I would like to place annotations on a map for each location and have the subtitle for the callout be the address of the coordinate, found by using reverseGeocodeLocation
In the for loop, I call the reverseGeocodeLocation
method, and inside the completion block I create the annotation and display it on the map. However, when I run the app, only one annotation shows up. I went in the debugger, and the completion block is only getting called once (for two calls to the reverseGeocodeLocation
method). Any suggestions to fix this?
My for loop:
for(int i = 0; i < [locations count]; i++)
{
CLLocation *location = [locations objectAtIndex:i];
__block NSString *info;
NSLog(@"Resolving the Address");
[geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error)
{
NSLog(@"Found placemarks: %@, error: %@", placemarks, error);
if (error == nil && [placemarks count] > 0)
{
placemark = [placemarks lastObject];
info = [NSString stringWithFormat:@"%@ %@ %@ %@, %@",
placemark.subThoroughfare, placemark.thoroughfare,
placemark.postalCode, placemark.locality,
placemark.administrativeArea];
[self remainderOfMethod:location withAddress:info atIndex:i];
}
else
{
NSLog(@"%@", error.debugDescription);
}
} ];
}
And the method called at the completion block:
- (void) remainderOfMethod: (CLLocation *)location withAddress:(NSString *)info atIndex: (int)i
{
MKPointAnnotation* annotation = [[MKPointAnnotation alloc] init];
if (location != nil)
{
[annotation setSubtitle:[NSString stringWithFormat:@"%@", info]];
annotation.coordinate = location.coordinate;
[self.mapView addAnnotation:annotation];
}
}
Thanks!
