Question

I have a presentModelViewControler (A) which pops up when there is no network connectivity. Now i have a another presentModelViewController (B) which shows calendar.

Difficulty is when B is active i.e. shows calendar view then if internet goes down then A doesnot get active.

I want when B is active if A starts i.e. internet goes down, then it release B and pop up A.

        CalendarTestViewController *clau=[[CalendarTestViewController alloc]init];



        if (clau.modalViewController==TRUE) {


            [clau dismissModalViewControllerAnimated:YES];
            [NSThread sleepForTimeInterval:0.2f];


        }




        [self.navigationController presentModalViewController:inter animated:YES];//network view controller

        [inter release];

}

Answer 1

You have to do it in stages.

1. dismissModalViewControllerAnimated: on your calendar view.
2. wait until the view.modalViewController becomes nil
3. present network connectivity controller.

The second step is the one that isn’t obvious.

The way I did this is in my method that presents my equivalent of the network connectivity. I have a loop first watching the modalViewController property.

Something like:

-(void)presentNetworkModal
{
     while (myVC.modalViewController) 
     {
         [NSThread sleepForTimeInterval:0.2f];
     }
     [myVC presentModalViewController:myNetworkNotifier animated:YES];
}
