问题 So if you create a UISplitViewController with 'MasterView' and 'DetailView' setup like this in the 'MasterView' in portrait on the iPhone 6 Plus you push/show 'MasterView2' by pressing the item button and then you rotate the device I would expect to see this - 'MasterView2' | 'DetailView' but instead I get 'MasterView' | 'MasterView2' How should this be setup so on rotating the iPhone 6 Plus I get the expected 'MasterView2' | 'DetailView'? 回答1: for anyone interested here is how I solved the
