iOS Delegate Does Not Push or Present a View -


i have homeview , homedropdownview.

homedropdownview shown drop-down view on homeview.

homeview delegate of homedropdownview.

when action in homedropdownview want call delegate method in homeview , have delegate method present third view controller, testviewcontroller it's navigation controller.

if try launch testviewcontroller anywhere in class works fine - except delegate method.

there animations in homedropdownview putting call delegate method in complition not make view controller appear. , in case i'm using animation's don't fire anyway; there's resizing without animation.

testviewcontroller's init called viewdidload not viewwillappear , view dose not appear.

code:

homedropdownview

- (void)finalaction {     ...     [self calldelegateaction];     ...  - (void)calldelegateaction {     if ([self.delegate respondstoselector:@selector(launchtestview)] ) {         [self.delegate launchtestview];     } else {         dlog(@"error out user.");     } }

homeview

- (void)launchtestview {         //[self listsubviewsofview:self.parentviewcontroller.view];          nslog(@"delegate method | self: %@", self);          testviewcontroller *tvc = [[testviewcontroller alloc] initwithnibname:@"testviewcontroller" bundle:nil];         //[self.navigationcontroller presentviewcontroller:tvc animated:yes completion:nil];         //[self.view.window.rootviewcontroller presentviewcontroller:tvc animated:yes completion:nil];         //[self.navigationcontroller pushviewcontroller:tvc animated:yes];         appdelegate *appdelegate = (appdelegate *)[[uiapplication sharedapplication] delegate];         [appdelegate.tabbarcontroller.navigationcontroller presentviewcontroller:tvc animated:yes completion:^() {             nslog(@"done!");         }]; }

none of above approaches work. if put exact same code viewdidappear or put in button action method, work fine. @ time of calling delegate method's self homeview , subviews, including nav controller seem there. in tabcontroller-based project think of above acceptable ways call nav controller still.

what missing? why delegate method not want push/present viewcontroller on homeview's nav controller? it's i'm missing can't find reason in apple docs or other thread. help!

sadly turned out homeview being changed underneath execution of message. time homeview got message call no longer same homeview object had requested action in first place. not same delegate. done appear user same view being used different things. example of why should not destroy , re-create critical views. should have been using same view , reloading objects instead if knew sending messages. or had notion of control structure.

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...
