    Wire up the buttons to IBActions. Create your interface with an outlet for your UITextView (textView) and the current font size (fSize).

    Within the IBAction put this code:

    - (IBAction) fontPlusDown {
    fSize++;
    UIFont *newFont = [UIFont systemFontOfSize:fSize];
    [textView setFont:newFont];
}

    Adjust the code for reduction (fSize–).
