问题 In Apple's official Maps app for the iPhone, there is a small 'page curl' button in the lower-right corner. When you press it, the map itself peels back to reveal some options. I would like to duplicate this effect in my own app. I'm trying to use UIModalTransitionStylePartialCurl (Added in SDK 3.2).
