标题:
IPAD摄像头切换发生的问题
我这里在IPAD AIR和IPAD2都重现了一个摄像头切换的问题。
具体描述如下：
1.先打开前置摄像头，网络对方和我自己都能正确看到我的图像
2.然后切换后摄像头，网络对方看到切换后的画面，但我本机的画面冻结了。
3.随后再反复切换，网络对方都能正确反映切换的画面，但我本机的画面一直冻结不变。

您好，请问您是使用的SDK包里面的标准示例程序测试的，还是用您自己写的程序来测试的？
是否有使用的SDK包src目录下helloAnyChat来验证一下呢？

我参考helloAnyChat自己写的程序,helloAnyChat没有问题。我也觉得很奇怪，不知道是否有什么因素没有考虑？

是否没有更新SDK（.h头文件以及.a库）到最新的版本？
请将SDK输出的相关日志贴上来，我们帮您分析一下，谢谢。

请重新下载SDK包，更新里面的.a库文件，我们在11月份有更新一次。

更新了最新的SDK，还是不行。不过我发现了一个情况就是：
在我进行切换摄像头后，系统先回调了OnLocalVideoRelease但是不知道什么原因没有接着回调OnLocalVideoInit
所以本地窗口没有显示，而网络对方正常切换了画面。
希望这个线索有用。

反复测试就是：

所以本地窗口没有显示，而网络对方正常切换了画面。

您好，请将更新SDK之后的日志信息帖上来，我们帮您分析一下，谢谢。

以下是日志：我进行了两次handleDoubleTap，第一次只是触发了OnLocalVideoRelease，没有触发OnLocalVideoInit，所以导致本机的画面冻结，对方画面正常切换。

您好，请问你得工程结构是怎样的模式？
比如说，工程结构利用一个视图控制器类去管理全部的控制器类、用导航控制器结构，或是用 Storyboard 模式？
如果方便的话建议将摄像头切换发生问题的工程发邮件到：
chenxs@bairuitech.com
，我们帮您调试一下，谢谢！

没有用storyboard和nib直接在loadView中创建视图
