区分iOS中的单击和双击主页按钮

Question

I want to handle single click and double click on Home button separately. I know applicationWillResignActive: but it gets call in both conditions. applicationDidEnterBackground: but I want to process data before app goes in background not after.

Is there any way I can recognise single and double click on home button separately?

Answer 1

Nope. You can only see when your app enters the background (or terminates). You can't see why .

Answer 2

when application in running single click will call

• applicationwillresigned
• applicationDidEnterBackground

but double click will call only

• applicationwillresigned

and will wait for your response.

you can use bool to figure out whether it is double or single click
