Switching Views and Passing data

Can you post the relevant code in here for us to take a look at?

Ben, Thanks for your reply... I have sorted that problem out... I just started new projects several times until it ran. I didnt see you reply on time.... Ben by the way. I am intending to do something in my application that I dont know how to do... I am trying to click on a button to change the value in a input data given by the user contained in a text box. ( I am trying to change the units on that input data ..i.e multiply value by the conversion factor to go from imperial to metric or visceversa).. So once you convert the value the new value is in the same input text box. I also was thinking when I press the button for this action I would liketo switch the label on the button to "english" or "imperial" .. . Could you possible help me on this?

Sounds like it should be pretty straightforward! The first thing you need to do is create IBOutlets for everything that you want to access from code when the button is pressed. This means one for the UITextView and one for the UILabel. You'll also need an IBAction for the button press itself

Then you should be able to use those to update the fields as you wish. Here's some pseudo-code that might help:

- (IBAction)convert:(id)sender {
    // Get the input value from the UITextView
    int inputValue = self.textView.text;

    // Convert it to whatever you need...

    // Store it back in the text view
    self.textView.text = convertedValue;
    // (This might vary depending on which data type you use for convertedValue)

    // And update the label
    if ([self.label.text isEqualToString:@"English"]) {
        self.label.text = @"Imperial";
    }
    else {
        self.label.text = @"English";
    }
}

Ben, Thanks for your prompt reply, I ll try that and see how it works ...I let you know
