适用于所有企业的MKLocalSearchRequest [英] MKLocalSearchRequest for all businesses

问题描述

另一位新手iOS开发人员.我已经通过使用request.naturalLanguageQuery ="Restaurants"使我的代码可以显示本地业务，但是我想返回所有业务.我不知道通配符是什么.好像会这么简单.任何帮助将不胜感激.

Another newbie iOS developer. I've got my code working to show local businesses by using request.naturalLanguageQuery = "Restaurants", but I want to return all businesses. I can't figure out what the wildcard character is. Seems like it would be so simple. Any help would be greatly appreciated.

var latitude:CLLocationDegrees = 40.7056258
var longitude:CLLocationDegrees = -73.97968

var latDelta:CLLocationDegrees = 0.01
var longDelta:CLLocationDegrees = 0.01


var span:MKCoordinateSpan = MKCoordinateSpanMake(latDelta, longDelta)
var location:CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)
var region:MKCoordinateRegion = MKCoordinateRegionMake(location, span)
mapView.setRegion(region, animated: true)

let request = MKLocalSearchRequest()
request.naturalLanguageQuery = "Restaurants"
request.region = mapView.region

推荐答案

我要说的是，鉴于naturalLanguageQuery就是这种情况:

I'd say that given the fact that this is the case for naturalLanguageQuery:

此属性不能为空.

This property can not be nil.

并且没有任何方式表明进行基于正则表达式的搜索，这是不可能的.我会为您的任务检查POI数据的另一个来源.

And no way is indicated to do a regex-based search, it's not possible. I'd check out another source of POI data for your task.
