objective c - Neither connectionDidFinishLoading: nor didFailWithError: get invoked -


calling 

connectioninprogress = [[nsurlconnection alloc] initwithrequest:request delegate:self startimmediately:yes];

when disconnect , reconnect internet simulator. 1 call initwithrequest: not causing neither connectiondidfinishloading: nor didfailwitherror: invoked.

i call in loop , getting following results (when disconnected).

didfailwitherror: fetch failed: internet connection appears offline.

next call after few seconds (as internet reconnected).

didfailwitherror: fetch failed: server specified hostname not found.

and next time call neither of 2 callbacks being invoked.

i ran same problem iphone simulator.

after 6 hours of debugging, googling , searching stackoverflow have found solution: the iphone simulator has bug! (or @ least tests proved).

when disconnect wifi/internet cable mac trying simulate network connectivity disappearing, not simulated in iphone simulator! (in fact if notice wifi connectivity icon on simulator not disappear)

i have tried deploy app (which creates nsurlconnection well) on iphone 4, , if put in airplane mode didfailwitherror gets called! while instead not happening on simulator!

note using xcode 4.0 , developing ios 4.3

so answer is: try deploy app on real ios device , work!
