Disqualify lead in Dynamics CRM (iOS) - ios

Question

How can i disqualify lead in Microsoft Dynamics CRM ? Is there any particular API for doing this from iOS platform?
I tried this :
for (id key in [details allKeys]) {
if([key isEqualToString:#"LeadState"])
{
[contactPostDict setObject:#"2" forKey:#"State"];
}
else if([key isEqualToString:#"LeadStatus"])
{
[contactPostDict setObject:#"6" forKey:#"Status"];
}
}
This is the error:
"error": {
"code": "", "message": {
"lang": "en-US", "value": "Error processing request stream. The property name 'Status' specified for type 'Microsoft.Crm.Sdk.Data.Services.Lead' is not valid."
}
}

Answer 1

I have never worked on the iOS platform but from the error that is being thrown, the error seems to be pretty straight forward.
You are looking for the keys "Status" & "State" but they don't exist. Instead you should be looking at their schema names which is as follows
Status = statuscode, State = statecode
Can you try modifying the code to use the above keys and see if you still gets the same error.

(BOOL)setLeadStatus:(NSString *)ID andDetails:(NSMutableDictionary *)details
{
NSString *uri = [MSDYNAMICS_AUTHENTICATION_CALL stringByAppendingPathComponent:[NSString stringWithFormat:#"LeadSet(guid'%#')/",ID]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:uri]];
request.HTTPMethod = #"MERGE";
[request setValue:JSON_CONTENT_TYPE_PARAMETER forHTTPHeaderField:#"Content-Type"];
[request setValue:JSON_CONTENT_TYPE_PARAMETER forHTTPHeaderField:#"Accept"];
NSMutableDictionary *contactPostDict=[[NSMutableDictionary alloc]init];
for (id key in [details allKeys]) {
if([key isEqualToString:#"LeadState"])
{
[contactPostDict setObject:#"2" forKey:#"statecode"];
}
else if([key isEqualToString:#"LeadStatus"])
{
[contactPostDict setObject:#"6" forKey:#"statuscode"];
}
}
NSError *err;
NSData *postData=[NSJSONSerialization dataWithJSONObject:contactPostDict options:NSJSONWritingPrettyPrinted error:&err];
NSString* postString = [[NSString alloc] initWithData:postData encoding:NSUTF8StringEncoding];
//NSString *postString = #"";
[request setValue:JSON_CONTENT_TYPE_PARAMETER forHTTPHeaderField:CONTENT_TYPE_PARAMETER];
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]];
SURLConnection *conn = [[SURLConnection alloc] init];
NSData *responseData = [conn sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *err1 = [[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(#"error: %#",err1);
if(responseData.length==0 && [conn.response statusCode] == 204)
{
[self getLeadDetailsForID:ID];
return YES;
}
else{
NSString *err = [[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(#"error: %#",err);
}
return NO;
