presentModalViewController无法全屏显示

如何解决presentModalViewController无法全屏显示

| 仅横向应用程序。在主窗口xib上，我有一个UIView。我正在以编程方式将UIScrollview加载到该UIView中，效果很好。在该scrollview上，我有一个按钮，该按钮通过presentModalViewController调用调出一个“详细信息”屏幕（一个单独的视图控制器）：

    LearnITViewController *learnit = [[LearnITViewController alloc] initWithNibName:@\"LearnITViewController\" bundle:nil];
self.learnitView = learnit;
[self presentModalViewController:learnit animated:YES];    
[learnit release];

当滚动视图为子视图时，将调用该动作，但模式视图不会占据整个屏幕。相反，它会弹出父滚动视图并翻转方向等。这不是所需的行为。 当调用来自scrollview时如何使模式视图全屏显示，这是主XIB上容器UIView的子视图吗？     

解决方法

        感谢所有的评论。在覆盖presentModalViewController并在循环中冒泡直到到达主控制器（在我的情况下为HomeViewController）的某个地方找到了提示。像冠军一样工作。

- (void) presentModalViewController:(UIViewController *)screen animated:(BOOL)animated {
    UIResponder *responder = self;
    while (responder && ![responder isKindOfClass:[HomeViewController class]]) {
        responder = [responder nextResponder];
    }
    [(UIViewController *)responder presentModalViewController:screen animated:YES];
}

我正在重写UIScrollview的.m文件，该文件包含进行调用的按钮。     ,        尝试将

subview

而不是

presentModelViewController

加为：

LearnITViewController *tempView = [[LearnITViewController alloc] initWithNibName:@\"LearnITViewController\" bundle:[NSBundle mainBundle]];
self.learnITViewController = tempView;
[tempView release];
[self.view addSubview:mainMenuView.view]; 

并添加此

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
// Return YES for supported orientations.
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);//or left
}

    ,        

LearnITViewController *learnit = [[LearnITViewController alloc] initWithNibName:@\"LearnITViewController\" bundle:nil];
self.learnitView = learnit;
[self.learnitView setsetWantsFullScreenLayout:YES];

要么

self.learnitView.wantsFullScreenLayout = YES;
[self presentModalViewController:learnit animated:YES];    
[learnit release];

    ,        代替

self

，在

superview

中添加

UIViewController

。

LearnITViewController *learnit = [[LearnITViewController alloc] initWithNibName:@\"LearnITViewController\" bundle:nil];
self.learnitView = learnit;
[self.view.superview presentModalViewController:learnit animated:YES];    
[learnit release];
