multithreading - Background update issue on iOS app -


i'm trying make "auto-update" process make user stay updated every x minutes while app's awake. i'm doing it's background call every x minutes asks server if there updates make or not.

the thing when make call , server returns yes, i've got to update 2 things: local db , user interface (cause there might changes on interface too).

what i've got thread problem. if don't make drawing while app's updating i've got no issue, when app crashes.

any ideas how control threading issue?

i'm assuming using coredata database. need make sure updates make managed object context occur on thread on context created (typically main thread).

you need make sure updates make user interface occur on main thread.

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...
