iOS 16地图开发：本地搜索与路线规划全解析

1. iOS 16中使用MapKit进行本地搜索

在iOS 16里，借助MapKit的本地搜索功能，能够利用自然语言字符串开展地图搜索。下面是一段示例代码，用于搜索“Pizza”相关的地点：

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

let search = MKLocalSearch(request: request)
search.start(completionHandler: {(response, error) in
    if error != nil {
        print("Error occurred in search: \(error!.localizedDescription)")
    } else if response!.mapItems.count == 0 {
        print("No matches found")
    } else {
        print("Matches found")
        for item in response!.mapItems {
            print("Name = \(item.name)")
            print("Phone = \(item.phoneNumber)")
        }
    }
})

上述代码的执行步骤如下：
