Apple CLGeocoder，MKLocalSearch结果与设备映射结果不同

在我的应用程序中使用位置字符串进行搜索时，它将返回5结果，但与默认设备映射应用程序不匹配。Apple CLGeocoder，MKLocalSearch结果与设备映射结果不同

我的代码1：CLGeocoder

CLGeocoder *geocoder = [[CLGeocoder alloc] init]; 
[geocoder geocodeAddressString:searchKey completionHandler:^(NSArray* placemarks, NSError* error){ 
    dispatch_async(dispatch_get_main_queue(), ^{ 
     if (placemarks.count > 0) { 
      searchLocations = placemarks; 
     } else { 
      searchLocations = nil; 
     } 
     [searchTableView reloadData]; 

     for (CLPlacemark *placemark in placemarks) { 
      NSLog(@"place dic %@",placemark.addressDictionary); 
     } 
    }); 
}];

代码2：MKLocalSearch

CLLocation *userLoc = (CLLocation *)[[MYLocationManager defaultManager] currentLocation]; 
MKLocalSearchRequest *request = [[MKLocalSearchRequest alloc] init]; 
request.region = MKCoordinateRegionMakeWithDistance(userLoc.coordinate, 100000, 100000); 
request.naturalLanguageQuery = searchKey; 
MKLocalSearch *search = [[MKLocalSearch alloc] initWithRequest:request]; 
[search startWithCompletionHandler:^(MKLocalSearchResponse * _Nullable response, NSError * _Nullable error) { 
    NSMutableArray *locs = [[NSMutableArray alloc]init]; 
    for (MKMapItem *placeM in response.mapItems) { 
     [locs addObject:placeM.placemark]; 
    } 
    if (locs.count > 0) { 
     searchLocations = locs; 
    } else { 
     searchLocations = nil; 
    } 


    dispatch_async(dispatch_get_main_queue(), ^{ 
    [searchTableView reloadData]; 
    }); 
}];

两者都返回相同的结果
