UIPopover锁定背景视图 [英] UIPopover locking background view

问题描述

我正在尝试复制iPad密码视图。这基本上是没有箭头方向的弹出窗口，它将背景视图锁定为类似于模态视图控制器。

I am trying to replicate the iPad passcode view. Which basically is a popover with no arrow direction, that locks the background view kinda like a modal view controller.

我的问题：有没有办法在呈现弹出窗口时锁定基础背景视图。

My question: Is there a way to lock the underlying background view when presenting a popover.

我的想法：我能想到的唯一真正的解决方案是将popover放在模态视图控制器中。并以这种方式呈现。

My idea: The only real solution that i could come up with is placing that popover inside a modal view controller. and presenting it that way.

想法？

推荐答案

使用视图控制器的 modalInPopover 属性： http://developer.apple.com/iphone/library/documentation/uikit/reference/UIViewController_Class/Reference/Reference。 html＃// apple_ref / doc / uid / TP40006926-CH3-SW72

Use the modalInPopover property of your view controller: http://developer.apple.com/iphone/library/documentation/uikit/reference/UIViewController_Class/Reference/Reference.html#//apple_ref/doc/uid/TP40006926-CH3-SW72

这个问题提供了一些关于制作没有箭头的弹出窗口的信息，尽管它不是明确是否正确：没有任何箭头的UIPopover

This question provides some information on making a popover with no arrows, though it's not clear whether it's correct or not: UIPopover without any arrows
