獲取MKLocalSearch以僅返回地點

Question

我已查看過文檔，找不到使用MKLocalSearch僅返回區域的方法。例如，我想搜索世界各地的城市，城鎮，村莊&縣但不返回任何企業或酒店等。這是可能的嗎？

感謝

Answer 1

我認爲你可以使用謂詞是這樣的：

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

例如，本地搜索代碼也增加，這將解決您的問題。

-(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]; 
    } 
}]; 

}

根據您的需要更改addressDictionary的關鍵參數。

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