iOS模式視圖控制器PageCurl動畫未顯示

Question

我有一個ParentViewController這是在UIScrollView連同SiblingsViewControllers像下面的樹。

• RootViewController
  • UIScrollView
    • HomeViewController
    • ParentViewController
      • FormNotesViewController - 模態視圖使用頁面捲曲廣告素材
    被呈現
    • FooViewController
    • BarViewController

的ModalViewController由ParentViewController在IBAction爲帶有下面的功能。

- (IBAction)onNoteOpen:(id)sender { 
FormNotesViewController *notesView = [[FormNotesViewController alloc] initWithNibName:@"FormNotesViewController" bundle:nil]; 

//OPTION #1 
notesView.modalTransitionStyle = UIModalTransitionStylePartialCurl; 
notesView.modalPresentationStyle = UIModalPresentationFullScreen; 
[self presentModalViewController:notesView animated:YES]; 


//OPTION #2  
// [UIView beginAnimations:@"PartialPageCurlEffect" context:nil]; 
// [UIView setAnimationDuration:1.0]; 
// [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; 
// [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp 
//       forView:notesView.view cache:NO]; 
// [self.view addSubview:notesView.view]; 
// [UIView commitAnimations]; 
} 

我已經嘗試了選項＃1和＃2。儘管它們都顯示了notesView，但應用程序未能顯示轉換。

我搞不​​明白爲什麼。

難道是因爲UIScrollView？難道是我錯過了什麼嗎？任何建議來調試這個？

選項1：

FormNotesViewController *notesView = [[FormNotesViewController alloc] initWithNibName:@"FormNotesViewController" bundle:nil]; 

notesView.modalTransitionStyle = UIModalTransitionStylePartialCurl; 

[self presentModalViewController:notesView animated:YES]; 

選項2：

[UIView beginAnimations:nil context:nil]; 
[UIView setAnimationDuration:1.0]; 
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; 
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:notesView.view cache:YES]; 
[self.view addSubview:notesView.view]; 
[UIView commitAnimations];
