iOS 10 UIImagePickerController 黑屏
<p><p>我遇到了一个奇怪的问题....<br/>
在运行 <code>iOS 10</code> 的设备上，相机预览显示黑屏。<br/>
但在<strong>旧版本中它可以正常工作</strong>。<br/>
我正在使用 <code>UIImagePickerController</code> 和 </p>
<pre><code>self.sourceType = UIImagePickerControllerSourceTypeCamera;
</code></pre>
<p>我的 info.plist 文件:</p>
<p> <a href="/image/OkfWZ.png" rel="noreferrer noopener nofollow"><img src="/image/OkfWZ.png" alt="enter image description here"/></a> </p>
<p> <a href="/image/0Csn5l.jpg" rel="noreferrer noopener nofollow"><img src="/image/0Csn5l.jpg" alt="enter image description here"/></a> </p>
<p>示例项目:<a href="https://github.com/arturdev/cameraTest" rel="noreferrer noopener nofollow">https://github.com/arturdev/cameraTest</a> </p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我用不同的方法解决了这个问题。</p>
<p>不要创建 UIImagePickerController 的子类，因为 Apple 不支持 UIImagePickerController 的子类。</p>
<p>重要</p>
<blockquote>
<p>The UIImagePickerController class supports portrait mode only. This
class is intended to be used as-is and does not support subclassing.
The view hierarchy for this class is private and must not be modified,
with one exception. You can assign a custom view to the
cameraOverlayView property and use that view to present additional
information or manage the interactions between the camera interface
and your code.</p>
</blockquote>
<p>这里是替代解决方案:</p>
<p>在 UIViewController 中添加这段代码</p>
<blockquote>
<pre><code>self.imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
self.imagePickerController.showsCameraControls = NO;
self.imagePickerController.delegate = self;
;
;
;
</code></pre>
</blockquote>
<p>在所有 iOS 版本和设备上都能正常工作。 :):)</p></p>
