The main focus of this day was extending the Storm Viewer app according to a set of challenges:
-
Use Interface Builder to select the text label inside your table view cell and adjust its font size to something larger – experiment and see what looks good.
-
In your main table view, show the image names in sorted order, so “nssl0033.jpg” comes before “nssl0034.jpg”.
-
Rather than show image names in the detail title bar, show “Picture X of Y”, where Y is the total number of images and X is the selected picture’s position in the array. Make sure you count from 1 rather than 0.
