如何在swift中使用MKLocalSearchCompletionHandler

Question

MKLocalSearchCompletionHandler completionHandler = ^(MKLocalSearchResponse *response, NSError *error)
{ ... };

如何在swift中转换此完成处理程序？

Answer 1

以下是一些示例代码：

let localSearchRequest = MKLocalSearchRequest()
localSearchRequest.naturalLanguageQuery = "restaurants"

let localSearch = MKLocalSearch(request: localSearchRequest)
localSearch.startWithCompletionHandler { (localSearchResponse, error) -> Void in
    print(localSearchResponse)
}

Answer 2

以下是与Swift3兼容的示例代码：

let localSearchRequest = MKLocalSearchRequest()
localSearchRequest.naturalLanguageQuery = "restaurants"

let localSearch = MKLocalSearch(request: localSearchRequest)
localSearch.start { (localSearchResponse, error) -> Void in
    print(localSearchResponse ?? "no results")
}
