How to perform UIButton action before loading next view

问题

I have a view where a user enters 3 sting fields. On the button press the fields are stored in an array. The button also changes the view.

The problem im having is when I get the strings from the array in the other view. The values that are being returned are the pervious values that have been entered.

I have added some lines to log what is going in and what is come out of the arrays. From the log I can see that the array is being called before it is set.

How to I get the button to run its action before it changes the view?

Here is my log:

2012-09-27 14:56:49.530 BeerDivider[1585:907] GetArray:(null)
2012-09-27 14:56:49.543 BeerDivider[1585:907] SetArray:(
    3,
    will,
    Harry
)

EDIT: Here is my code. http://pastebin.com/BX5gqp17

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([segue.identifier isEqualToString:@"yourSegue"]) {
       //do what you need
    }
}
