ios - Why does my NSURLSession dataTask make multiple calls to the server? -


i have nsurlsession datatask created using following method:

nsurlsessionconfiguration *defaultconfigobject = [nsurlsessionconfiguration defaultsessionconfiguration];     nsurlsession *defaultsession = [nsurlsession sessionwithconfiguration: defaultconfigobject delegate:hvc delegatequeue:    [nsoperationqueue mainqueue]]; nsurlsessiondatatask * datatask = [defaultsession datataskwithurl:url ];     [datatask setaccessibilitylabel:@"userprofiling"];      [datatask resume];

here, hvc viewcontroller handling delegate server data task call.

i see datatask making multiple calls server continuously.

is there way ensure 1 call made?

this has been solved , answered below.

i answering own question here.

by mistake, writing above code in method being called repeatedly. corelocation framework continuously updating user's location.
