无论如何，iPad模态表单占据了整个屏幕 [英] iPad modal form sheet takes up the whole screen anyways

问题描述

我正在尝试在iPad上创建一个表单模式，它应该是540x620模式视图。

I'm trying to create a form sheet modal on iPad, which should be a 540x620 modal view.

我创建了一个带有NIB文件的视图控制器其视图是540x620大小的UIView（上面有东西）。

I've created a view controller with a NIB file whose view is a 540x620 sized UIView (with stuff on it).

我将模态演示样式设置为 UIModalPresentationFormSheet ，并在当前视图控制器上调用 presentModalViewController：animated：。

I set the modal presentation style to UIModalPresentationFormSheet, and call presentModalViewController:animated: on the current view controller.

我的视图从底部滑入，但它不是一张表单，而是占据了整个屏幕（我的视图元素都锚定在左上角）屏幕）。

My view slides in from the bottom, but instead of being a form sheet, it takes up the whole screen (my view elements are all anchored in the top left of the screen).

更奇怪的是，当我解雇它时，所有在它下面的用户界面都被重新布置在中心，大约在一张表单中屏幕中央的大小区域。 Bizarro！

Even stranger, when I dismiss it, all the UI that was "underneath" it, is all re-layed out to be in the center, in approximately a form sheet sized area in the center of the screen. Bizarro!

任何人都有什么可能导致这种行为的建议？

Anyone have any suggestions as to what could cause this behavior?

谢谢。

推荐答案

想出来。我在父视图控制器上设置模式演示样式 - 需要在新创建的子控制器上设置它。人们需要将其视为孩子的财产，而不是父母所控制的财产。

Figured this out. I was setting the modal presentation style on the parent view controller-- it needs to be set on the newly-created child controller. One needs to think of it as a property of the child, not something the parent controls.

我会删除这个问题，但我想把它留作路标对于未来的任性。

I would delete this question, but figure I'll leave it as a signpost for the future wayward.
