Wait After PresentModalViewController

I need to wait (not execute code) after the currentModalViewController until the modal view is rejected, is this possible or a conceptual error?

-(NSDictionary *)authRequired
{
    //This view write the settings when dismissed (plist)
    [self presentModalViewController:loginRegView animated:YES]; 
    //Read from the setting file (plist) and send back (it a delagate method)
    NSMutableDictionary *ret=[[NSMutableDictionary alloc] init];
    [ret setObject:[app.settings get:@"user"] forKey:@"user"];
    [ret setObject:[app.settings get:@"pass"] forKey:@"pass"];
    return ret;
}

What you need to do is create a protocol LoginRegViewControllerDelegate

that the view controller is attached to, representing the Modal View Control, and your LoginRegViewController

(or his name) will send a message to it delegate

that it just closes / closes. In this delegate method, your delegate view manager should read the settings you just configured and do whatever it wants with them.

To make your view controller (modal view) more flexible and reusable you can use NSNotificationCenter

. Here's a link to the class.



Your modal view should have a notification that it will be closed. Any other controller that needs to respond to this notification must add the observer to the same notification center.
