问题 iOS Notes and Mail apps have a three-pane split view interface on iPad landscape mode. How can I create such interface? I checked UISplitViewController but it made only two panes (master and detail). Can somebody please enlighten me how to create the leftmost pane? 回答1: It's done using custom layout.
