内存泄漏-应用程序退出信号9。

I have an application which is dealing with many data structures, uiimageviews, videos, creating bit map context and so on. Every time the application is crashing on its continuous usage for a long time. The application is crashing with the memory warning --> Application exited abnormally with signal 9. What may be its reason. What does signal 9 means.

我有一个应用程序，它处理很多数据结构，uiimageviews，视频，创建位图上下文等等。每次应用程序在长时间的连续使用中崩溃。应用程序与内存警告一起崩溃——>应用程序在信号9中异常退出。可能是它的原因。信号9意味着什么?

I think this is due to the memory issue. Your app is using lot of memory due that is app is killed..

我认为这是由于记忆问题。你的应用程序使用了大量的内存，因为这是应用程序被杀死了。

It sounds like it might be related.

听起来好像有关系。

It can also be a privacy/permission issue. We forgot to add NSCameraUsageDescription and UILaunchStoryboardName to Info.plist file and our app crashed with error Message from debugger: Terminated due to signal 9

它也可以是隐私/权限问题。我们忘记添加NSCameraUsageDescription和UILaunchStoryboardName到Info。plist文件和我们的应用程序在调试器中出现错误消息:由于信号9而终止。

After adding the following lines to Info.plist the app sopped crashing.

在添加以下行信息之后。这款应用程序被淘汰了。

<key>NSCameraUsageDescription</key>
<string>The app would like to let you make a picture.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>The app would like to let you choose an item from your Photos.</string>
