iphone - How to make UIDatePicker to show user selected time -

-

i have uidatepicker letting user chose time . uitableview in uiview on click of uibutton uiddatepicker appears, when user choose time , press button dismiss uiddatepicker view , if wants check whats time had chose in uiddatepicker. uiddatepicker doesn't show time user had selected shows current time or time start time of datepicker . i want display time user has chosen user when opens datepicker again. code when user press uibutton display uiddatepicker view 

-(ibaction)settingsbuttonchanged:(uibutton *)sender {      usertimepicker = [[uidatepicker alloc]init];     [usertimepicker addtarget: self                        action: @selector(usertimepickervaluechanged:)forcontrolevents: uicontroleventvaluechanged]; }

this code lets datepicker have custom time limit

-(ibaction)datepickertimenbuttonchanged:(uibutton *)control {      if (control.tag == 1)     {         self.selectedbutton = control.tag;          int starttime = 7;         int endtime = 11;          nsdate *date1 = [nsdate date];         components = [gregorian components: nsuintegermax fromdate: date1];          [components sethour:starttime];;         [components setminute:00];          nsdate *startdate = [gregorian datefromcomponents:components];          [components sethour:endtime];         [components setminute:00];          nsdate *enddate = [gregorian datefromcomponents:components];          morningbutton.selected = yes;         afternoonbutton.selected = no;         eveningbutton.selected = no;         nightbutton.selected = no;          [usertimepicker setdatepickermode:uidatepickermodetime];          [usertimepicker setminimumdate:startdate];         [usertimepicker setmaximumdate:enddate];          [usertimepicker setdate:startdate animated:yes];         [usertimepicker reloadinputviews];      }      if (control.tag == 2)     {         self.selectedbutton = control.tag;          morningbutton.selected = no;         afternoonbutton.selected = yes;         eveningbutton.selected = no;         nightbutton.selected = no;          int starttime = 12;         int endtime = 15;          nsdate *date1 = [nsdate date];         components = [gregorian components: nsuintegermax fromdate: date1];          [components sethour:starttime];         [components setminute:00];          nsdate *startdate = [gregorian datefromcomponents:components];          [components sethour:endtime];         [components setminute:00];          nsdate *enddate = [gregorian datefromcomponents:components];          [usertimepicker setdatepickermode:uidatepickermodetime];          [usertimepicker setminimumdate:startdate];         [usertimepicker setmaximumdate:enddate];          [usertimepicker setdate:startdate animated:yes];         [usertimepicker reloadinputviews];      } }

code lets user selects own time

-(void) usertimepickervaluechanged:(uibutton *)sender {      switch (self.selectedbutton)     {         case 1:         {             nsuserdefaults *userselectedmorningtime = [nsuserdefaults standarduserdefaults];              nsdate *selectedmorningtime = [usertimepicker date];              nslog (@"setting: morningtimekey");              storedmorntime = selectedmorningtime;              [userselectedmorningtime setobject:selectedmorningtime forkey:@"morningtimekey"];             [userselectedmorningtime synchronize];         }             break;          case 2:         {             nsuserdefaults *userselectedafternoontime = [nsuserdefaults standarduserdefaults];              nsdate *selectedafternoontime = [usertimepicker date];              nslog (@"setting: afternoontimekey");              storedafternoontime = selectedafternoontime;              [userselectedafternoontime setobject:selectedafternoontime forkey:@"afternoontimekey"];             [userselectedafternoontime synchronize];         }             break; }

from make out code saving selected time nsuserdefaults, never using saved time it.

my guess if change should work. 

-(ibaction)datepickertimenbuttonchanged:(uibutton *)control {     nsuserdefaults *defaults = [nsuserdefaults standarduserdefaults];      if (control.tag == 1)     {         self.selectedbutton = control.tag;          int starttime = 7;         int endtime = 11;          //saved morning time date user defaults         nsdate *date1  = [defaults objectforkey:@"morningtimekey"];         if(!date1) date1 = [nsdate date];         components = [gregorian components: nsuintegermax fromdate: date1];          [components sethour:starttime];;         [components setminute:00];          nsdate *startdate = [gregorian datefromcomponents:components];          [components sethour:endtime];         [components setminute:00];          nsdate *enddate = [gregorian datefromcomponents:components];          morningbutton.selected = yes;         afternoonbutton.selected = no;         eveningbutton.selected = no;         nightbutton.selected = no;          [usertimepicker setdatepickermode:uidatepickermodetime];          [usertimepicker setminimumdate:startdate];         [usertimepicker setmaximumdate:enddate];          [usertimepicker setdate:startdate animated:yes];         [usertimepicker reloadinputviews];      }      if (control.tag == 2)     {         self.selectedbutton = control.tag;          morningbutton.selected = no;         afternoonbutton.selected = yes;         eveningbutton.selected = no;         nightbutton.selected = no;          int starttime = 12;         int endtime = 15;          //saved afternoon time date user defaults         nsdate *date1  = [defaults objectforkey:@"afternoontimekey"];         if(!date1) date1 = [nsdate date];          components = [gregorian components: nsuintegermax fromdate: date1];          [components sethour:starttime];         [components setminute:00];          nsdate *startdate = [gregorian datefromcomponents:components];          [components sethour:endtime];         [components setminute:00];          nsdate *enddate = [gregorian datefromcomponents:components];          [usertimepicker setdatepickermode:uidatepickermodetime];          [usertimepicker setminimumdate:startdate];         [usertimepicker setmaximumdate:enddate];          [usertimepicker setdate:startdate animated:yes];         [usertimepicker reloadinputviews];      } }

this baffling me @ moment. i'm experienced programmer looking throw bit of surprise fiancee on countdown page our wedding. desired effect simulated confetti falling behind main page. setup follows: i have array of divs in javascript. each div absolutely positioned on page. have interval set updates every 50 or milliseconds. on each tick, run loop on array of divs, , calculations , update positions. problem problem having, however, though can see divs created, stored array, , modified (in case, each has slight randomized rotation) during initialization phase, once tick update position starts, div stored in whatever last slot of array gets position updated. tried hard-coding each div index testing purposes, strictly last element update position. upon printing current "left" , "top" style values each div before , after calculations shows value has been changed, no visible change noticeable. here's basic code: javascript var container;
