iphone - IOS: pageViewController interface orientation -

i create code:

self.pageviewcontroller = [[pageviewcontroller alloc] initwithtransitionstyle:uipageviewcontrollertransitionstylescroll navigationorientation:uipageviewcontrollernavigationorientationhorizontal options:@{ uipageviewcontrolleroptioninterpagespacingkey : @30 }]; self.pageviewcontroller.delegate = self; self.pageviewcontroller.datasource = self; self.pageviewcontroller.automaticallyadjustsscrollviewinsets = no; self.currentmediaplayerviewcontroller = [self createmediaplayerviewcontrollerwithmediaitem:self.mediaitems[self.pageindex]]; nsarray *pageviewcontrollers = @[self.currentmediaplayerviewcontroller]; [self.pageviewcontroller setviewcontrollers:pageviewcontrollers                                   direction:uipageviewcontrollernavigationdirectionforward                                    animated:no                                  completion:nil]; [self addchildviewcontroller:self.pageviewcontroller]; [self.pageviewcontroller didmovetoparentviewcontroller:self]; [self.view addsubview:self.pageviewcontroller.view]; 

i enable landscape orientation in parentvc pageviewcontroller. still can catch rotation.

- (void)viewdidload {  self.navigationcontroller.delegate = self;  nsnumber *value = @(uiinterfaceorientationlandscapeleft); nsstring *keyorientation = @"orientation"; if (![value isequaltonumber:@((nsinteger)[[uidevice currentdevice] valueforkey:keyorientation])]) {     [[uidevice currentdevice] setvalue:value forkey:@"orientation"]; }   - (nsuinteger)navigationcontrollersupportedinterfaceorientations: (uinavigationcontroller *)navigationcontroller { return uiinterfaceorientationmasklandscape; 

how can enable landscape orientation in pageviewcontroller?

try use code

- (bool)shouldautorotate {     return yes; }  - (nsuinteger)supportedinterfaceorientations {     if (self.islandscapeok) {         // iphone, return uiinterfaceorientationmaskallbutupsidedown         return uiinterfaceorientationmaskall;     }     return uiinterfaceorientationmaskportrait; }
