Modizer asks to reset settings when it was autoclosed #13

Closed mistydemeo closed 12 years ago

mistydemeo commented 12 years ago

Modizer will display its post-crash "reset your settings" prompt after being autoclosed by the OS. In practice, I find this means that most times when I open it I'm asked whether I want to wipe my settings - which I don't! I wonder, is there a better way to handle this?

I'm using an iPod Touch October 2011 with iOS 5.0.1.

Hi,

Basically it depends on what is happening when an app is "autoclosed". It just the matter of calling [detailViewControlleriPhone saveSettings]; [detailViewControlleriPhone updateFlagOnExit]; //the one used to identify clean or dirty exit

Today they are both called when the app is closed "normally". So you just need to know what objective C method is called and add the 2 lines to exit cleanly.

According to Apple's developer docs, there is no guaranteed method that will be called to notify an app of termination if it's inactive; applicationWillTerminate is only guaranteed if the application is in the foreground and is going to be terminated. An inactive background application may receive a sigkill at any time.

So, updateFlagOnExit should always be set on applicationDidEnterBackground, rather than conditionally as it is right now - that may be all that's necessary to fix this.
