2.注意点

相比于iphone多了个分栏控制器
//边栏控制器（自动添加了手势 自动弹回功能）
@property(nonatomic,strong)UISplitViewController *spiltVC;

ipad特有的控制器
UIPopoverController

3.代码展示

AppDelegate.h

//详情界面
@property(nonatomic,strong)SHDetailViewController *detailVC;
//左侧边栏的表格界面
@property(nonatomic,strong)SHRootTableViewController *rootVC;
//边栏控制器（自动添加了手势 自动弹回功能）
@property(nonatomic,strong)UISplitViewController *spiltVC;
