iphone - iOS 7 - didUpdateLocations delegate not called after app goes in background -


i'm able receive location updates on (simulators , ipad device) iphone device. 

self.locationmanager = [[[cllocationmanager alloc] init] autorelease]; self.locationmanager.desiredaccuracy = kcllocationaccuracybestfornavigation; self.locationmanager.pauseslocationupdatesautomatically = no; self.locationmanager.delegate = self;  - (void)locationmanager:(cllocationmanager *)manager didupdatelocations:(nsarray *)locations {     cllocation *newlocation = locations.lastobject;     nslog(@"didupdatelocations newlocation = %@", newlocation); . . }

i receive didupdatelocations (nslog message) long app in foreground after press home button (i.e. app goes in background), stop receiving notifications in didupdatelocations. 'console' doesn't show nslog message , thereafter location icon in status bar goes away within 10 seconds.

what works doesn't -

  1. appears ios 6 installed on other iphone 3gs works fine. little location icon doesn't go away.

  2. test on ipad device ios 7 , app keeps running in background.

  3. all simulators (iphone , ipad) ios 6 ios 7 works expected.

  4. when test on iphone 4 ios 7, app doesn't run in background. probably, issue on ios 7 (and specific iphone devices).

i think found cause of problem. "settings" app in ios 7 has general > "background app refresh" turned off :( turned "on", app started running in background :)

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
