窗口的旋转而不是 ViewController
首先我是一个n00b。经过长时间的尝试和研究，我决定寻求一些外部帮助。 我的项目： 我为儿童制作了一本书，但被拒绝了，因为它只允许纵向。 看来苹果也想要颠倒过来。 在我的 appdelegate 中，我切换 ViewController（我的书的页面），旋转起作用。 但在页面后面，我有来自应用程序代理的窗口，页面正在旋转，但不是我的窗口/背景。 在我的委托中，我如何以及在何处可以（允许）纵向和上下颠倒旋转我的窗口？ 这是我的应用程序代表：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIImage *bg = [UIImage imageNamed:@"t2.jpg"];
UIImageView *tisch = [[UIImageView alloc] initWithImage:bg];
tisch.frame = CGRectMake(0, 0, 768, 1024);
[window addSubview:tisch];
[tisch release];
[self addButtonNext];
[self initAnimation];
[self animieren:self.animation];
[self playNavigation];
[self addButtonStop];
[self addButtonPlay];
[window makeKeyAndVisible];
return YES;
}
有什么想法吗？ 如果有人能帮助我，那就太酷了！ 预先感谢普朗基
First of all i am a n00b. After long time of trying and research i decided to get some external help.
My Project:
i made a book for children, but it was rejected because it only allowed portrait orientation.
it seams apple wants upside-down as well.
in my appdelegate i switch the ViewControllers (Pages of my Book), there the rotation works.
But behind the Pages i have the window from my appdelegate, the pages are rotating but not my window/background.
How and where in my delegate can i (allow) rotate my window in portrait and upside-down?
Here my appdelegate:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIImage *bg = [UIImage imageNamed:@"t2.jpg"];
UIImageView *tisch = [[UIImageView alloc] initWithImage:bg];
tisch.frame = CGRectMake(0, 0, 768, 1024);
[window addSubview:tisch];
[tisch release];
[self addButtonNext];
[self initAnimation];
[self animieren:self.animation];
[self playNavigation];
[self addButtonStop];
[self addButtonPlay];
[window makeKeyAndVisible];
return YES;
}
Any ideas?
It would be really cool if anyone could help me!
Thanks in advance Planky

首先，当你说“看来苹果也想要颠倒过来”时，这是非常令人惊讶的。大多数 iOS 应用程序明确不支持颠倒方向，因为这通常会带来糟糕的用户体验。它们仅支持纵向和左/右横向。
接下来，不要将子视图直接添加到 win
dow中。这几乎总是错误的，并且绕过了内置的轮换逻辑（正如您所发现的）。只需使用UIViewController。这就是它的用途。您可以（尽管通常不应该）向window.rootViewController.view添加内容，但这实际上仅适用于特殊问题（例如跨对等视图的拖放）。只需使用视图控制器即可。它将立即解决您 90% 的问题。不是每个页面有一个视图控制器，而是只有一个 PageViewController 来更改它显示的页面。然后，PageViewController 可以将所有这些额外的 UI 元素放入视图中。
First, when you say "it seams apple wants upside-down as well" this is very surprising. Most iOS applications explicitly do not support upside-down orientation since it is often a poor user experience. They only support portrait and left/right landscape.
Next, do not add subviews directly to the win
dow. This is almost always wrong and bypasses the built-in rotation logic (as you've discovered). Just use aUIViewController. That's what it's for. You can (though you generally shouldn't) add things to thewindow.rootViewController.view, but this is really only for specialized problems (like drag-and-drop across peer views). Just use a view controller. It will solve 90% of your problems out of the box.Rather than having a single view controller per page, just have a single PageViewController that changes which Page it displays. The PageViewController can then put all these extra UI elements into the view.
