Question

I have a class called Packet which responsible for receiving packets.
inside this class I want to change the view controller
the current view controller is: JoinViewController.
the class defined as

@interface Packet : NSObject

I have tried the following code but it doesn’t work here is code:

 case PacketTypeMytype:
    {
        GameViewController *gameViewController = [[GameViewController alloc] initWithNibName:@"GameViewController" bundle:nil];
        JoinViewController *join=[[JoinViewController alloc]initWithNibName:@"JoinViewController" bundle:nil];

        [[join navigationController]pushViewController:gameViewController animated:YES];

Answer 1

You need to pass the instance of JoinViewController to the packet object (as a weak reference) instead of creating a new one.
