Run a method after subclass of UIAlertView gets dismissed

Question

I create custom login page by using UIAlerView subclass. Now when i click on button it opens up UIAlertView I want to change the main view based on which button is pressed.

But as all implementation of UIAlerView is in another class though i change the view it doesn't retain that as that class variable doesn't get it's value.

Can anyone please help me with this? I can post the code if required.

Thank you, Ankita

You can use a custom init method like below for alertView and store the _sender in global or class variable. like

id sender;
- (id)initWithSender:(id)_sender
{
    self = [super init];
    if (self) {
        sender=_sender;
    }
    return self;
}

from RootVC/bgview initialize alertView as follows and define a method named

-(void) alertIndexSelected:(NSInterger) index;

{
//change the backgound view based on button selected
}

in rootvc/your main view.

  alertViewobj =[[alertView alloc] initWithSender:self];

when the button is selected on alertview call the below method, this will notify your rootvc about which index of alert is pressed. use following alertview delegate.

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
[sender alertIndexSelected: buttonIndex];
}
