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];      } }

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

How to call a javascript function after the page loads with a chrome extension? -

-
there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey? (function submitaction() ). both chrome extensions , greasemonkey offer ways specify when script inject if executed. in chrome extension, you set in manifest : "content_scripts": [ { "run_at" : "document_idle", in greasemonkey compatible userscripts, set in metadata // @run-at document-end in both cases, have add script if want ensure resources loaded when function executed : document.addeventlistener('load', submitaction);
