objective c - How can one display Gregorian calendar year for an NSDate when calendar in iOS settings is Japanese or Buddhist -


i trying display 4 digit gregorian year of nsdate while calendar set japanese. 

nslog(@"date joined: %@", self.datejoined); nscalendar *calendar = [[nscalendar alloc] initwithcalendaridentifier:nsgregoriancalendar]; nsdateformatter *formatter = [[nsdateformatter alloc] init]; formatter.calendar = calendar; formatter.locale = [[nslocale alloc] initwithlocaleidentifier:@"en_us"]; formatter.timezone = [nstimezone timezonewithabbreviation:@"est"]; formatter.dateformat = @"yyyy"; nslog(@"year joined: %@", [formatter stringfromdate:self.datejoined]);

log:

date joined: 2012-05-29 22:13:54 +0000 year joined: 4000

what doing wrong?

try this. works.

nscalendar *cal = [[nscalendar alloc] initwithcalendaridentifier:nsgregoriancalendar];  nsdatecomponents *datecomps = [cal components:(nsyearcalendarunit) fromdate:self. datejoined];  nslog(@"date = %d",[datecomps year]);  // ignore if using arc [cal release];

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...
