Question

I have a UIPopoverController named popover in another view. What I would like to know is, how can I dismiss the popover if a UIButton was pressed in the current popover view? Thanks in advance.

You could use an NSNotification to tell the other view to dismiss it’s popover view.

Example usage:

// Add an observer that will respond to our notification.
[[NSNotificationCenter defaultCenter] addObserver:self // <- This is the object that will has the selector that we want to run (the same one we use in the next line).
                                         selector:@selector(doSomething:) // <- This is the selector we want to run.
                                             name:@"doSomethingNow" // <- This is notification name we will send to activate our observer's selector.
                                           object:nil]; // Don't worry about this for now.


// Post the notification. This has the same name as our observer above, so our 'doSomething' selector should be run.
[[NSNotificationCenter defaultCenter] postNotificationName:@"doSomethingNow" object:nil];


// the function specified in the same class where we defined the addObserver
- (void)doSomething:(NSNotification *)pNotification {
    NSLog(@"Received Notification..."); 
}
