Answer 1

Glad to inform all that after long 4 days of continuos research, I got this problem solved! I got the solution from this Linkedin thread

You just need to make a few changes in the code:

NSURL *url = [NSURL URLWithString:@"http://api.linkedin.com/v1/people/~/mailbox"];

    OAMutableURLRequest *request =
    [[OAMutableURLRequest alloc] initWithURL:url
    consumer:oAuthLoginView.consumer
    token:oAuthLoginView.accessToken
    callback:nil
    signatureProvider:nil];
    [request setHTTPMethod:@"POST"];
    NSString *messageToPerson = @"/people/email=target@gmail.com";
    NSDictionary *person = [[NSDictionary alloc] initWithObjectsAndKeys:[[[NSDictionary alloc] initWithObjectsAndKeys:messageToPerson,@"_path",@"TargetFirstName",@"first-name",@"TargetSecondName",@"last-name",nil] autorelease], @"person",nil]; 
    NSArray *valueArray = [[NSArray alloc] initWithObjects:person,nil];
    NSDictionary *values = [[NSDictionary alloc] initWithObjectsAndKeys:valueArray,@"values", nil];
    NSDictionary *ir = [[NSDictionary alloc] initWithObjectsAndKeys:[[[NSDictionary alloc] initWithObjectsAndKeys:@"friend",@"connect-type",nil] autorelease], @"invitation-request",nil];
    NSDictionary *ic = [[NSDictionary alloc] initWithObjectsAndKeys:ir,@"item-content", nil];
    NSDictionary *update = [[NSDictionary alloc] initWithObjectsAndKeys:values,@"recipients",@"Invitation",@"subject",@"ConnectWithMe",@"body", ir, @"item-content", nil];
    [request setValue:@"json" forHTTPHeaderField:@"x-li-format"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    NSLog(@"%@",[update description]);
    NSString *updateString = [update JSONString];

    [request prepare];

    [request setHTTPBodyWithString:updateString];

    OADataFetcher *fetcher = [[OADataFetcher alloc] init];
    [fetcher fetchDataWithRequest:request delegate:self
        didFinishSelector:@selector(postUpdateApiCallResult:didFinish:)
        didFailSelector:@selector(postUpdateApiCallResult:didFail:) withId:1];

    [request release];

and in oAdata OADataFetcher.m

- (void)fetchDataWithRequest:(OAMutableURLRequest *)aRequest delegate:(id)aDelegate didFinishSelector:(SEL)finishSelector didFailSelector:(SEL)failSelector  withId:(int)idtm
    {

    [request release];
    
request = [aRequest retain];

    delegate = aDelegate;
    
didFinishSelector = finishSelector;

    didFailSelector = failSelector;

//note this change

    if (idtm!=1) {
   
    [request prepare];
    
       }

connection = [[NSURLConnection alloc] initWithRequest:aRequest delegate:self];
    
}
    

Try this. Will work for sure. Hope this will help future visitors.
