Changes

The last user interface object we need to add is a label where the result of the conversion will be displayed. Add this by dragging a Label object from the Library window to the View and position it beneath the button. Stretch the width of the label so that it is approximately a third of the overall width of the view and reposition it using the blue guidelines to ensure it is centered in relation to the button.

Double click on the label to highlight the text and press the backspace key to clear the text (we will set the text from within a method of our View Controller class when the conversion calculation has been performed). Though the label is now no longer visible it is still present in the view. If you click where it is located it will be highlighted with the resize dots.

At this point the user interface design phase of our project is complete and the view should appear as illustrated in the following figure. We now are ready to try out a test build and run.
