dismissViewControllerAnimated calling method in another view

I am new to iOS Programming and now i have a problem.

There is a login screen that use [self presentViewController:loginview animated:YES completion:nil]; to show it out in MasterViewController.

And now i want to call a method (reload data) after [self dismissViewControllerAnimated:YES completion:nil]

this is my code: 

[self dismissViewControllerAnimated:YES completion:^ {
   [self getPostData];                 // Reload Data
   [self.tableView reloadData];        // Reload Data
}];

but it is not working.

(the reload method is in the MasterViewController)

Anyone can help me?

You can call the presentingViewController's methods which updates the Presenting view.

for example: I have a modal view which can be launched from multiple Views. And all the presenting views have the view reloading code within view will appear.

Add the below code before dissmissing the modal view.

        [self.presentingViewController viewWillAppear:YES];

[self dismissViewControllerAnimated:YES completion:Nil];

what you should do is basically call method on presenting view controller as below

[(MasterViewController*)self.presentingViewController reloadData];

You can use NSNotificationCenter for your problem.

Define a NSNotification in your MasterViewController viewDidLoad like below

 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(closeModal:) name:@"CloseModal" object:nil];

And then define the method as below

-(void)closeModal:(NSNotification *)notification{
    UIViewController *controller=(UIViewController *)notification.object;

    [controller dismissViewControllerAnimated:YES completion:^ {
         [self getPostData];                 // Reload Data
         [self.tableView reloadData];        // Reload Data
    }];

}

And at last from your other controller from where you are actually trying to dismiss your controller use code below

[[NSNotificationCenter defaultCenter] postNotificationName:@"CloseModal" object:self];
