Как настроить размер viewcontroller на странице viewcontroller

Question

Я пытаюсь использовать приложение с помощью pageviewcontroller.

Я добавил viewcontroller как childviewcontoller.
Но, как вы можете видеть на рисунке, красное пространство появляется сверху.
Как я могу избавиться от него?

Спасибо заранее.

добавлены коды

Answer 1

вы можете попробовать эту строку кода может быть это может решить вашу проблему, и если до сих пор вы столкнулись с проблемой, то комментарий мне

UIPageViewController *pageViewController 
[pageViewController.view setFrame:self.view.frame]; 

Answer 2

я надеюсь, что это будет работать. , ,

-(void) loadView 
{ 

    UIView * pView = [[UIView alloc] initWithFrame:[UIScreen mainScreen].bounds]; 

    self.view = pView ; 

    [pView release]; 

    pView = nil; 

}
