如何将一个Dialog View控制器作为子视图添加到UIView或副Versa？ [英] How can I add a Dialog View Controller as a Subview to a UIView or Vice Versa?

问题描述

我有一个对话框视图。我有一个对话框视图。我有一个对话框视图。控制器和它的根只是显示一个类似于iphone音乐歌曲可滚动视图布局的字符串列表。我需要的是位于屏幕顶部的子视图和下面的可滚动DVC。我需要顶视图总是在视图中，而用户可以滚动根元素，因为顶视图将持有统计信息。

我已经尝试添加一个子视图，但它只是重叠的dvc下面，我没有能够找出一种方法添加dvc作为子视图到UIView。

任何帮助将非常感激。

解决方案

是实现这是一个单一的根视图控制器，主机两个子视图控制器。一个子视图包含窗口顶部的统计信息。底部子视图包含保存对话框视图的导航控制器。

I have looked around the web for some time looking for any resources on this topic and have come up with nothing that solves my dilemma.

I have a dialog view controller and its root is simply displaying a list of strings similar to how the iphone music song scrollable view is laid out. What I need is a subview located at the top of the screen and the scrollable DVC below it. I need to the top view to be always in view while the user can scroll through the root element because the top view will be holding statistics.

I have tried adding a subview but it simply overlaps the dvc below it, and I have not been able to figure out a way to add a dvc as a subview to a UIView.

Any help would be much appreciated.

解决方案

What is needed to achieve this is a single root view controller that hosts two subview controllers. One subview contains the statistics at the top of the window. The bottom subview contains a navigation controller that holds the dialog view.
