iPad上不规则形状的模态视图

问题描述

是否可以使用 presentModalViewController 显示不规则形状的模态视图？模态部分覆盖屏幕（演示文稿样式设置为 UIModalPresentationFormSheet ）

Is it possible to display an irregularly shaped Modal view using presentModalViewController? The modal is covering the screen partially (presentation style is set to UIModalPresentationFormSheet)

我尝试简单地设置superview clipsToBounds 为NO，它不起作用。我似乎也无法摆脱圆角。

I tried simply setting the superview clipsToBounds to NO, it didn't work. I can't seem to get rid of the rounded corner as well.

PS：我试图避免创建自定义视图并手动执行此操作。

PS: I am trying to avoid having to create a custom view and do this manually.

PPS：我从文档中注意到我们现在应该在iOS 5中使用 presentViewController 它没有完成虽然有任何不同。

PPS: I noticed from the docs that we are supposed to use presentViewController now in iOS 5. It didn't accomplish anything different though.

推荐答案

我有点工作了。这有点像黑客，但它确实有效。

I sort of got it working. It's a bit of a hack, but it works.

代码（这是产生模态的控制器内部）：

The code (this is inside the controller who spawn the modal):

// Present the modal
[self presentViewController:modalVC animated:YES completion:NULL];

// Let content overflow and shrink superview to a small dimension
modalVC.view.clipsToBounds = NO;
modalVC.view.superview.bounds = CGRectMake(modalVC.view.superview.bounds.origin.x, modalVC.view.superview.bounds.origin.y, 100, 100);

现在只需让模态的视图比superview更大，你就可以对形状发疯了。

Now just make the modal's views bigger than the superview and you can go crazy with the shape.

请注意，触摸只会在超级视图区域注册。

Note that touches will only register on the superview area.
