当我连接到Web服务，返回JSON字符串返回他们像XML：如何连接web服务并获取json数据？
2014-02-07 00:17:15.673 Test[791:70b] <\?xml version="1.0" encoding="utf-8"?>
<\string xmlns="MBSCafe.Service.ServiceManager">{"query": [{"ID": "01","Name": "food"}]}<\/string>
相反，我想这一点：
{"query": [{"ID": "01","Name": "food"}]}
这是我的部分代码：
NSString *urlString = @"http://mbsserver/MBSCafeService/ServiceManager.asmx/GetItemTypeList";
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod: @"POST"];
[request setValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Accept"];
NSString *myRequestString = @"id="; // Attention HERE!!!!
myRequestString = [myRequestString stringByAppendingString:@"01"];
NSData *requestData = [NSData dataWithBytes:[myRequestString UTF8String] length:[myRequestString length]];
[request setHTTPBody: requestData];
它有什么问题？
您检查WebService的JSON响应，如果无论如何，如果这是不可能的，然后调用Web服务并将XML转换为JSON与[XMLReader]（http://troybrant.net/blog/2010/09/simple-xml-到的NSDictionary转换器/）。 – cjd
