ibeacon - iPhone background bacon ranging stopping as of screen PW lock issue -


we have ios bacon ranging app works fine in background on ipad air , mini when screen pw locks.

we have blocker bug iphones 5s/6 of password screen lock, beacon ranging stops. (we have set nsdefaults plist attributes nsfileprotectionnone, not issue.)

the beginbackgroundtaskwithexpirationhandler keep alive forever hack not work more couple minutes.

questions: how can app on iphone ranging beacons in background after screen password locks (which think makes app state inactive)?

when lock screen displayed, ios app not in foreground, , limits on how long allowed run in background kick in.

using beginbackgroundtaskwithexpirationhandler "hack", an app can range beacons in background 180 seconds after lock screen comes up, or beacon entry/exit event occurs. what seeing on iphone expected behavior. limit imposed os , not bug.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
