我想打印SOAP響應myTableViewController

Question

你好，我是新來的斯威夫特和SOAP，我米使用http://www.webservicex.net/globalweather.asmx並得到響應，posts我想打印response到myTableViewController請幫助三江源
響應

{Country = ""GetCitiesByCountryResult = "<NEWDATASET><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>BHAIRAWA AIRPORT</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>JUMLA</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>KATHMANDU AIRPORT</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>POKHARA AIRPORT</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>SIMRA AIRPORT</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>SURKHET</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>TAPLEJUNG</CITY></TABLE><TABLE><COUNTRY>NEPAL</COUNTRY><CITY>BIRATNAGAR AIRPORT</CITY></TABLE></NEWDATASET>";}

檢查你的代碼後，我發現你的問題是你沒有正確解析XML數據。

獲取「GetCitiesByCountryResult」的值後，可以將其轉換爲xml數據並再次解析，以獲取所有城市的列表作爲數組。在此之後，你可以將它傳遞到ViewController進一步結果

let xmlArray = posts.value(forKey: "GetCitiesByCountryResult") as! [String] 
let xmlString: String = xmlArray[0] 

if let xml_Data:Data = xmlString.data(using: String.Encoding.utf8) { 
    parser = XMLParser(data: xml_Data) 
    parser.delegate = self 
    parser.parse() 
}
