How do I call a method from another view controller

I want to call this method:

- (void)getUserFriendTargetDialogRequest {
    currentAPICall = kAPIFriendsForTargetDialogRequests;
    [self apiGraphFriends];
}

from this conditional statement that's in another viewcontroller:

if (idx == 2) {
        NSLog(@"you touched menu 2");

        APICallsViewController *apiViewController = [APICallsViewController alloc];
        [self.navigationController pushViewController:apiViewController animated:YES]; 
    }

can anyone help with the syntax on this?

thanks so much

1>Just alloc the class in which the method is and then call it through object of that class.

ViewControllWithMethod *view=[ViewControllWithMethod  alloc]]init];
[view getUserFriendTargetDialogRequest];

2>Instead of instance method you can make it as class method then you will be able to call it through className.getUserFriendTargetDialogRequest

First, you probably also want to init your APICallsViewController via:

    APICallsViewController *apiViewController = [[APICallsViewController alloc] initWithNibName:nil bundle:nil];

Then if that getUserFriend... is a method of APIViewController, you can do this:

    [apiViewController getUserFriendTargetDialogRequest];

However, since you aren't passing any arguments in from your other view controller, you might consider calling it in the init method, or the viewDidLoad method of APICallsViewController.

OtherViewController *viewController = [[OtherViewController alloc]         
                                           init];
[viewController methodName];
[viewController release];
