ios - View presented from master panel of UISplitViewController not rotating when rotated from portrait to landscape (iPad) -

-

i presenting modal view , action sheet master panel of uisplitviewcontroller. ios 9.3

1) if present view when ipad in portrait mode , rotate ipad landscape, screen not rotating.enter image description here
2) if present view when ipad in landscape mode , rotate ipad portrait, screen rotating.

how can achieve rotation?

there 2 solutions resolve issue:

  1. it not ideal present modal views master panel should doing uisplitviewcontroller itself. 

    splitviewcontroller.preferreddisplaymode =uisplitviewcontrollerdisplaymodeallvisible; // displaying master panel in screen shot in question modalviewcontroller.modalpresentationstyle = uimodalpresentationformsheet; // displaying modalviewcontroller in form sheet style [splitviewcontroller presentviewcontroller:modalviewcontroller animated:true completion:nil]; // note: modalviewcontroller presented uisplitviewcontroller , not master panel of split view

  2. the master panel of spilt view presented in popover when in portrait mode device rotation changes have go through popovercontroller. guessing chain breaks @ points. so, resolve issue call 

    [splivc setpreferreddisplaymode:uisplitviewcontrollerdisplaymodeprimaryhidden];

before modal presentation segue called(from prepareforsegue). not sure of whether delegates working approach.

edit: have observed if split view in uisplitviewcontrollerdisplaymodeallvisible mode presenting modal vc master panel(lets simple modal segue in storyboard) not give rotation issue. have confirmed in ios 9.3 simulator.
