As in my application if some action regarding "httpcall" are posted in the mainthread and my app is waiting for a response from server and same time home button is pressed than although app is entering background but IOS delegates (such as "didEnterBackground") are not getting called till the response are received.

Also sometime even if I'm relaunching the app its not responding till it gets crashed by itself.

Note:I'm using CyberLink code for my HTTP posts.
