在另一个UIView中显示UIImagePickerController [英] Displaying UIImagePickerController within another UIView

问题描述

我在UIImagePickerController的最后几个月工作的很多，尤其是在OS3.1中的新功能，以及相机视图顶部的重叠视图。这已经很好了。

I've been working pretty extensively the last couple months with UIImagePickerController, particularly with the new capabilities in OS3.1 and newer to overlay views on-top of the camera view. This has worked just fine.

但是，我目前正在一个项目，我想在现有视图中显示UIImagePickerController的摄像机视图。

However, I am currently working on a project where I'd like to be able to display the camera view of the UIImagePickerController within an existing view. Essentially, the exact opposite of what I've currently been doing.

一个例子是带有导航组件的View控制器（想想顶部和底部的水平条带渐变），并且在点击这些条之一上的按钮时，内容区域显示相机视图。快门动画应该向上，顶部和底部的导航栏将始终在顶部。

An example would be a View Controller with navigation components (Think top and bottom horizontal bars with gradients), and upon tapping a button on one of these bars, then content area displays the camera view. The shutter animation would should up, and the top and bottom navigation bars would remain always on-top.

我已经成功添加UIImagePickerController到窗口视图，作为

I've had success adding the UIImagePickerController to the window view, as well as presenting it modally, but haven't had any luck adding it as a subView.

例如：

[window addSubview:camera.view];
[self presentModalViewController:camera animated:YES];

推荐答案

所有你需要做的是调用viewWillAppear和viewDidAppear。

All you need to do is call viewWillAppear and viewDidAppear.

下面是一个示例，其中_pickerController是UIImagePickerController的实例：

Here is an example where _pickerController is an instance of UIImagePickerController:

[self.view addSubview:_pickerController.view];
[_pickerController viewWillAppear:YES];
[_pickerController viewDidAppear:YES];
