如何为启用了后台功能的iOS应用程序获取applicationWillTerminate通知？

Question

So I'm aware that applicationWillTerminate: will not be called if your app supports background execution (unless there's some memory issue), and applicationDidEnterBackground: is called instead.

Inside of the applicationDidEnterBackground: method in the appDelegate, it says

// If your application supports background execution, 
//this method is called instead of applicationWillTerminate: when the user quits.

However, I need to save some entries into a dictionary when the user actually quits the app. I do not want to do this every time the app enters the background though. Is there a way to get the termination notification even though my app supports backgrounding?

Specifically if the app is force quit by the user, what is some sort of workaround to get a notification of this?

Answer 1

save every time the app enters into the bg. the os may THEN kill you without any further warning.
