Push to new ViewController from connectionDidFinishLoading - ios

Question

Is it possible to push to a new view controller from ConnectionDidFinishLoading ?
I have the following and it performs the ConnectionDidFinishLoading but does not push to new view controller.
-(void)connectionWithURLString:(NSMutableArray *)urlString
{
NSDate *now = [NSDate date];
int userID = [[clientDataStruct.clientData objectForKey:#"number"] intValue];
NSDate *date = self.datePicker.date;
// NSLog(#"obj: %#", urlString);
NSString *extrString = [NSString stringWithFormat:#", customerdetails:{customer_id = %d, job_date = %#, date_created = %#}",userID,date, now];
NSString *post = [NSString stringWithFormat:#"json=quote:{%#%#}", urlString, extrString ];
NSLog(#"post: %#", post);
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:NO];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *value = [defaults objectForKey:#"value"];
NSString *jsonUrl = [NSString stringWithFormat:#"xxx?task=add_quote&user_id=%#&customer_id=%#",value, [clientDataStruct.clientData valueForKey:#"number"]];
[request setURL:[NSURL URLWithString:jsonUrl]];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:postData];
NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
if (!connection)
NSLog(#"Connection failed!");
}
- (void)Success
{
UIStoryboard *subVc = [UIStoryboard storyboardWithName:#"MainStoryboard_iPad" bundle:nil];
UserTableView *userTable = [subVc instantiateViewControllerWithIdentifier:#"UserTableView"];
userTable.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self.navigationController pushViewController:userTable animated:YES];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog(#"%#", error);
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[self performSelectorOnMainThread:#selector(Success) withObject:Nil waitUntilDone:YES];
NSLog(#"connectionDidFinishLoading%#", connection);
}
Everything works, and returns my data and data gets added into the SQL. My NSLog shows that ConnectionDidFinishLoading. But it does not push to the new View Controller.
Thanks for the help, being scratching my head on this one.
Thanks to Fahim advise allowed me to debug further, The Navigation view broke with a returned model controller. Changed it to push and all is working

Point 1
This is not working with you because you don't have navigation controller. Make sure that you have navigation controller.
Point 2
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[self performSelectorOnMainThread:#selector(LoginSuccess) withObject:Nil waitUntilDone:YES];
NSLog(#"connectionDidFinishLoading%#", connection);
}
This is something wrong. Even if user have entered incorrect username or password, you are still allowing user to get logged in.
Check the response that you are getting in connectionDidFinishLoading and then based on this response do the transition.
e.g. if you have PHP at backend your code will be
sql query here to add data
if (data added) {
echo "valid";
} else {
echo "invalid";
}
now check this response in connectionDidFinishLoading and based on this do the transition

Answer 2

First check that if your LoginSuccess is getting called if yes then paste this
UserTableView * userTable =[self.storyboard instantiateViewControllerWithIdentifier:#"UserTableView"];
[self.navigationController pushViewController:userTable animated:YES]
like this but replace ResultsTableView with UserTableView
