“Pushing the same view controller instance more than once is not supported” exception

Question

I am using the following code to retrieve some messages and putting them into my inbox.

MyInboxVC *inboxVC=[MyInboxVC get ];
//upload all the pending messag         


        

Answer 1

It means you are pushing the same viewcontroller object to stack again when it's already in there.

[self.navigationController pushViewController:viewControllerObj animated:NO];

[self.navigationController pushViewController:viewControllerObj animated:NO];

check if u r pushing inside a loop or if u've accidentally placed the code more than one time..
