iphone - Stop setKeepAliveTimeout handler from being called after application came foreground? -


for voip application sending ping packet server every 10 minutes using setkeepalivetimeout, works fine, i'm not sure how stop handler being called once application came foreground.

eg: here how set timeout

 [[uiapplication sharedapplication] setkeepalivetimeout:600 handler:^{ [self backgroundhandler]; }];

background handler:

- (void)backgroundhandler {     printf("10 minute time elapsed\n");     // action... }

above function being called after application came foreground, have read in apple documentation set handler nil stop it. have tried below in applicationwillenterforeground 

[uiapplication sharedapplication] setkeepalivetimeout:600 handler:nil];

still i'm getting call every 10 mins. how handle this, need use flag only.

any appreciated.

you have invoke clearkeepalivetimeout stop timer. setkeepalivetimeout: designed keep voip connection on , that's why it's periodically called.
