Xcode App Crash-When connecting to the ODATA services [on hold]
- by user3685677
Can someone help me resolving the following issue:
When trying to connect from iPad app to SAP ECC system through ODATA channel services via SUP, it is allowing me to login for the first time and could retrieve the data successfully from SAP system. But when I logout and try logging in again with the same session, application gets crashed. Below is the crash report for your reference.
I am using SDM Parser to connect the SAP system.
SDMODataServiceDocumentParser *sdmDocParser = [[SDMODataServiceDocumentParser alloc] init];
[sdmDocParser parse:aServiceDocument];
m_serviceDocument = sdmDocParser.serviceDocument;
//Load the object with metadata xml:
SDMODataMetaDocumentParser *sdmMetadataParser = [[SDMODataMetaDocumentParser alloc] initWithServiceDocument:m_serviceDocument];
[sdmMetadataParser parse:aMetadata];
After initiated the service, setting the URL.
[service setServiceDocumentUrl:m_serviceDocumentURL];
Using SDMconnectivityhelper to connect the URL
id<SDMRequesting> serviceDocumentRequest2 = [connectivityHelper executeBasicSyncRequestWithQuery3:[[ODataQuery alloc]initWithURL:[NSURL URLWithString:encodedStrUrl]]] ;
- (id <SDMRequesting>)executeBasicSyncRequestWithQuery3:(ODataQuery *)aQuery
{
id<SDMRequesting> request = [self createRequestWithQuery:aQuery];
[request setTimeOutSeconds:TIMEOUT_SEC];
[request setRequestMethod:@"GET"];
[request addRequestHeader:@"Content-Type" value:@"application/xml"];
[request startSynchronous];**[App getting CRASH in this line]**
return request;
}
- (id <SDMRequesting>)createRequestWithQuery:(ODataQuery *)aQuery
{
if (isSUPMode)
{
[SDMRequestBuilder setRequestType:SUPRequestType];
}
else
{
[SDMRequestBuilder setRequestType:HTTPRequestType];
}
id <SDMRequesting> request = [SDMRequestBuilder requestWithURL:aQuery.URL];
request.username = self.username;
request.password = self.password;
return request;
}
