Mail TabBarItem dismissModalViewControllerAnimated

Question

I'm adding TabBarItem (Email) dynamically. When I finish with my email, I'm calling 'dismissModalViewControllerAnimated' but it's simply dismissing mail view. How do I unload the view controller?

in my email view controller I'm doing following:

- (void)viewDidLoad => I would like to unload this view controller
{
    [super viewDidLoad];
    [self showEMail:nil]; => this display and dismisses email (I'm not calling present.. and dismiss... in a row. I'm using delegate methods to present and dismiss, which is fine.)
                              [self presentModalViewController:picker animated:YES];
                              [self dismissModalViewControllerAnimated:YES];

}

after selecting my tab bar item, it's loading view controller(Lets say 'ABC View controller') which is presenting my mail modal controller. mail modal controller is being dismissed properly. but I would like to come back to previously selected tab item after unloading the 'ABC view controller'. is it possible? or am i doing something wrong here?

Thanks in advance

Rama, your question is hard to understand. maybe you need to use delegation for the view controller you are presenting.

In your code, calling [self presentModalViewController...] and [self dismissModalViewController...] in a row doesn't make sense.

You shall call the [self presentModalViewController...] in the first place, make the presenting view controller as the delegate (picker.delegate = self, for instance)

let the modal view controller do its business including exiting (like user hits cancel, close or whatever), then call the delegation method (something like [delegate didFinish...] or [delegate didCancel...]

now it's the presenting view controller's turn to response to the delegation method calling, you can do the modal view controller dismissing here

Note: many UIKit classes practice this pattern, such as UIAlertView, UIActionSheetView, MPMoviePlayerViewController, etc. You shall check them and make your own

Apologies for not making it clear. I'm not calling present.. and dismiss... in a row. I'm using delegate methods to present and dismiss, which is fine. but how do I unload my view controller? – Krishna Apr 15 '12 at 08:45

you want to move back to other Tab Bar? – Chris Chen Apr 15 '12 at 13:51
yes, also I need to re-launch the modal presenter whenever they click on tab item. I've solved this by using select index and viewwillappear method as mentioned below. Thanks for your suggestions. cheers – Krishna Apr 15 '12 at 21:04

I've solved problem by using ViewWiilAppear method to display mail modal presenter.

and i'm selecting the index of tab bar controller after dismissing mail modal presenter.

self.tabBarController.selectedIndex =0;

This solved my problem.

Cheers
