Problem while Integrating Xcode with oData

Hi,

I am creating an iPad Application, which uses the NW Gateway Webservices.I am following these document

"SAP NetWeaver Gateway 2.0 Developer Tool for Xcode " I have followed the steps mentioned in document.

Now i am on the way to write the code.

I am facing an exception at the point where i am creating service

ZPLANNINGBOOK_0003Service *service = [[ZPLANNINGBOOK_0003Service alloc]init];

Please find below the code snippet & Console output.

Also please share the project links where i can find the oData+Xcode using SAP Proxy Tool.

--------------------------------------------

ProxyDemandPlanningViewController.m

-------------------------------------------

- (void)viewDidLoad

{

[super viewDidLoad];

NSLog(@"111");

// NSData *serviceDocResponse = [NSData alloc];

// NSData *serviceMetadataResponse = [NSData alloc];

SDMConnectivityHelper *connectivityHelper = [[SDMConnectivityHelper alloc]initWithUsername:@"USERNAME" andPassword:@"password"];

NSError *error = nil;

NSLog(@"after connect");

ZPLANNINGBOOK_0003Service *service = [[ZPLANNINGBOOK_0003Service alloc]init];

// ZPLANNINGBOOK_0003Service *service = [[ZPLANNINGBOOK_0003Service alloc] initWithServiceDocument:serviceDocResponse andMetadata:serviceMetadataResponse];

NSLog(@"222");

id<SDMRequesting> request = [connectivityHelper executeBasicSyncRequestWithQuery:service.t_columnsCollectionQuery];

NSLog(@"after ns executebasic connect");

NSData *itemsResponseData = request.responseData;

NSMutableArray *Columns = [service getT_columnsCollectionWithData:itemsResponseData error:&error];

for(int i = 0 ; i < Columns.count ; i++)

{

[Columns objectAtIndex:i];

NSLog(@"Count ==== %@ ",[Columns objectAtIndex:i]);

}

// Do any additional setup after loading the view, typically from a nib.

}

Hi,

Can you tell us what code is present in ZPLANNINGBOOK_0003Service ? And are you returning the response back when you made a GET request ?

Thanks,

Srikanth M

Hi Srikanth,

Thanks for your reply...

ZPLANNINGBOOK_0003Service is the service which is auto generated by SAP NW Proxy Tool.

I am getting exception on

ZPLANNINGBOOK_0003Service *service = [[ZPLANNINGBOOK_0003Service alloc]init];

So i am not able to move ahead after these line & finally not able to get the Response.

Please find below the code for ZPLANNINGBOOK_0003Service.m file
