Over the next six days I’ll introduce some of the features of our upcoming ExploreShanghai iPhone app! Today: pan and zoom. One of the tricky things about using a map on a small screen like the iPhone is navigating around. This is only going to get harder as more lines are added in Shanghai in the run-up to Expo 2010!

In ExploreShanghai, we solved this by using the iPhone’s standard “pinch to zoom” controls. When you launch the app you’ll be zoomed out. To zoom in, place two fingers on the screen and spread them apart. The map will zoom in to show you the area around your fingers. You can pan around the map by dragging with a single finger. See the image below to see how it works.
