how to detect lock and home button press event separately in iOS

Hi,

In the business logic we have an requirement where the iOS Lock and Home button press event captures separately is necessary.

I am able to add the "pause" and "resume" event. But there i didn't receive the the source of pausing the application. Like the app is paused because of screen lock timer or lock button press or home button press or call interrupt etc.

Can anybody help me to solve this issue on iOS.??

I am working on following configuration,

Titanium SDK: 3.4.1

Titanium Studio: 3.4.1

xCode: 6.0.1

nodeJs: 0.10.13

Any help is highly appreciable.
