Today, in the pop-up Uiprintinteractioncontroller, on the IOS10 and 11 of the ipad test, found that has been protrait direction pop-up, the results appear as a bug:

Research for a long time, found that there is no implementation of the following proxy method:

-(Uiviewcontroller *) Printinteractioncontrollerparentviewcontroller: (Uiprintinteractioncontroller *) Printinteractioncontroller;

In fact, in the iOS9, do not implement this method, and, even if the implementation of this method, in Ios10 and IOS11, I did not achieve the iOS9 on the popup effect, only full-screen pop-up, like the effect on the iphone. Always feel like a bug on iOS.
