[SOLVED] How to pass Array to SOAP API?

How to pass Array to SOAP API?

I need to pass this array to SOAP API as a parameter. The back-end implementer is new to building APIs (C#/.NET) and I have never implemented this kind of API before. There are 4-5 Stack Overflow question related to this, but none of them were the solution as per my query.

NSArray *arr = [NSArray arrayWithObjects:@"1",@"2", nil];

NSString *soapURL = @"http://tempuri.org/IService1/addRecord";
NSString *soapBody = [NSString stringWithFormat:@"<addRecord xmlns=\"http://tempuri.org/\">"
                      "<id>%@</id>"
                      "<title>%@</title>"
                      "<record>%@</record>"
                      "</addRecord> \n” ,@“1”,@“abc", arr ];

NSLog(@"%@",soapBody);

Error:

value in string The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'addRecord'. End element 'record' from namespace 'http://tempuri.org/' expected. Found text '( 1, 2 )'.

One thing I came to know that I cannot pass array directly in to soapBody. What what is the alternative?

The API is working fine at the back-end.

Solution

Finally I resolved this issue with this code:

NSString *soapBody = [NSString stringWithFormat:@"< addRecord xmlns=\"http://tempuri.org/\" xmlns:arr=\"http://schemas.microsoft.com/2003/10/Serialization/Arrays\" > \n"
                          "<ID>1</ID>\n"
                          "<title>ABC</title>\n"
                          "<record>\n"];

    for (int i=0; i<arrRecord.count; i++) {
        soapBody = [NSString stringWithFormat:@"%@ <arr:int>%@</arr:int>\n",soapBody,arrRecord[i]];
    }

    soapBody = [NSString stringWithFormat:@"%@ </record></addRecord> \n",soapBody];

I needed to define "arr" in the parent node and type of element(int) in the record array.
