ios - UIDatePicker and date not storing properly -


i have ibaction method tied uitoolbarbutton runs following code.

the uidatepicker setup show time user. therefore, picker randomly chooses date: date today, date tomorrow. want picker choose time selected (but in future). e.g. if user picks 6:00am @ 10:00pm on jan 1st, want date store 6:00 on jan 2nd.

the following if should that, 50% of time nslog returns 1 answer , 50% of time returns other.

if (self.picker.date >= [nsdate datewithtimeintervalsincenow:0]) {     nsuserdefaults *defaults = [nsuserdefaults standarduserdefaults];     nsdate *pickerdate = self.picker.date;     [defaults setobject:pickerdate forkey:@"pickerdate"];     [defaults synchronize];     nslog(@"the date more now. pickerdate %@",pickerdate); } else {     nsuserdefaults *defaults = [nsuserdefaults standarduserdefaults];     nscalendar*       calendar = [[nscalendar alloc] initwithcalendaridentifier: nsgregoriancalendar];     nsdatecomponents* components = [[nsdatecomponents alloc] init];     components.day = 1;     nsdate * pickerdate = [calendar datebyaddingcomponents: components todate: self.picker.date options: 0];     [defaults setobject:pickerdate forkey:@"pickerdate"];     [defaults synchronize];     nslog(@"the date less now. pickerdate %@",pickerdate); }

edit: code modified, logic backwards problem remains.

you can't use >= (or similar) operator compare 2 nsdate objects. these objects. must use compare: method compare 2 dates. have comparing see if 1 object pointer greater or equal object pointer. not want.

the proper replacement be:

if ([self.picker.date compare:[nsdate date]] != nsorderascending) {

note [nsdate date] gives same result [nsdate datewithtimeintervalsincenow:0].

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
