Question

I have a navigation based application. when I click on a table’s row next view appears and back button (manually created )appears. Now i want to know how can I get the object of previous view in current view so that I can change one of the label’s text of previous view using previous view’s object ?

Thanks.

Answer 1

You can pass the value before pushing the second view to the necessary variable

secondViewController.variable = firstViewController.variable;

Then push the secondViewController

Update:
Use a Bool variable willBePoppedBack as class variable and set it as NO initially.

- (void)viewWillAppear {

    if(willBePoppedBack)
    {
    // your label text after pressing back button
    }
    else {
    // your label's default text
    }
}

You should set the variable willBePoppedBack to YES when you push to the next view.
