Found out the solution to the problem. The problem was setting the added frameworks as requiredinstead of optional
找到了解决问题的方法。问题是根据需要设置添加的框架而不是可选的
GO TO Project-> Targets-> Build Phases-> Link Binary with Libraries
转到项目-> 目标-> 构建阶段-> 将二进制文件与库链接
There, set the status of added frameworks to Optional
在那里，将添加的框架的状态设置为Optional
This solved my problem.
这解决了我的问题。

It may happen because of framework compilation. I worked out it
这可能是由于框架编译而发生的。我解决了
App target -> Build Phases -> Embed Frameworks.
应用程序目标 -> 构建阶段 -> 嵌入框架。
So mark copy only when installing on. Clean the project and run it!
所以只在安装时标记副本。清理项目并运行它！

You need to add this Framework to Xcode.
您需要将此框架添加到 Xcode。
Right-click on "Frameworks" > Choose Add > Existing Frameworks Locate "AVFoundation" then choose Add.
右键单击“框架”> 选择“添加”>“现有框架”找到“AVFoundation”，然后选择添加。
If you want to add it manually, choose the other button and navigate to:
如果您想手动添加它，请选择另一个按钮并导航到：
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.1.sdk/System/Library/Frameworks/AVFoundation.framework/
Replace the iPhone SDK version with whatever you are building against.
将 iPhone SDK 版本替换为您正在构建的任何版本。
Perhaps also see this answer: Missing AVFoundation.framework
也许还可以看到这个答案：Missing AVFoundation.framework
Also, sometimes you just need to close Xcode, then clean and rebuild.
此外，有时您只需要关闭 Xcode，然后清理并重建。
