让MKLocalSearch只返回位置

Question

我已经查看了文档，无法找到一种使用MKLocalSearch只返回区域的方法。例如，我希望搜索世界各地的城市，城镇，村庄和县，但不返回任何企业或酒店等。这可能吗？

谢谢

Answer 1

我认为您可以像这样使用谓词：

NSPredicate *noBusiness = [NSPredicate predicateWithFormat:@"business.uID == 0"];
NSMutableArray *itemsWithoutBusinesses = [response.mapItems mutableCopy];
[itemsWithoutBusinesses filterUsingPredicate:noBusiness]; 

示例本地搜索代码也在添加，这将解决您的问题。

-(void)issueLocalSearchLookup:(NSString *)searchString {
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(self.location.coordinate, 30000, 30000);
self.localSearchRequest = [[MKLocalSearchRequest alloc] init];
self.localSearchRequest.region = region;
self.localSearchRequest.naturalLanguageQuery = searchString;
self.localSearch = [[MKLocalSearch alloc] initWithRequest:self.localSearchRequest];

[self.localSearch startWithCompletionHandler:^(MKLocalSearchResponse *response, NSError *error) {
    if(error){
        NSLog(@"LocalSearch failed with error: %@", error);
        return;
    } else {
        for(MKMapItem *mapItem in response.mapItems){
            [self.data addObject:mapItem];
        }
        [self.searchDisplayController.searchResultsTableView reloadData];
    }
}];

}

根据您的需求更改addressDictionary的关键参数。

      for(MKMapItem *mapItem in response.mapItems)
    {
        NSLog(@"%@",mapItem.placemark.addressDictionary[@"Street"]);
}
