Calling WCF in iOS

The example compares the simple record the thought

1. Define entity and method declarations in interfaces

Login information
[OperationContract]
[WebInvoke (UriTemplate = "Loginf/{name}/{pwd}", Method = "POST", Responseformat = Webmessageformat.json)]
Loginf Getloginf (string name, string pwd);

2//Data Exchange entity class

[DataContract]
public class Loginf
{

[DataMember]
public string UserId {get; set;}

[DataMember]
public bool LogTag {get; set;}

[DataMember]
public string ErrMsg {get; set;}

}

3 Service implementations

Simple test

Public Loginf Getloginf (string name, string pwd)
{
Loginf Loginf = new Loginf ();
if (name = = "111" && pwd = = "111")
{

                Loginf. UserId = "100";
                Loginf. LogTag = true;
                loginf.errmsg = " Success ";

}
Else
{
Loginf. UserId = "0";
Loginf. LogTag = false;
Loginf.errmsg = "Verification Failed";
}
return loginf;
}

4 Change the binding mode to WebHttpBinding in Web. config

Binding= "WebHttpBinding"
