Question

I have a view which is pushed from another view. That second view has a text field. If I modified anything in the text field, that content is not present once I go back and then forward again. How can I save those data before the second view is popped up?

Answer 1

One way you could do this is with file persistence. Basically when you are exiting your second view, you need to write the data in the text field to a file and then read from this file when opening the second view.

My iOS is a little rusty but i think it would be something like this:

    -(void)viewDidLoad {
          -code to read from file
          -and display in text field
    }

    -(void)viewDidUnload {
          -code to save to file from text field
    }
