How to combine date and time from two UIDatePickers?

Question

I have two UIDatePickers in my app, one mode is for selecting date and other to time mode. I have fired a notification when the exact date and time is reached.

Answer 1

NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *dateComponents = [calendar components:NSDayCalendarUnit|NSMonthCalendarUnit|NSYearCalendarUnit fromDate:self.datePicker.date];
NSDateComponents *timeComponents = [calendar components:NSHourCalendarUnit|NSMinuteCalendarUnit fromDate:self.timePicker.date];

NSDateComponents *newComponents = [[NSDateComponents alloc]init];
newComponents.timeZone = [NSTimeZone systemTimeZone];
[newComponents setDay:[dateComponents day]];
[newComponents setMonth:[dateComponents month]];
[newComponents setYear:[dateComponents year]];
[newComponents setHour:[timeComponents hour]];
[newComponents setMinute:[timeComponents minute]];

NSDate *combDate = [calendar dateFromComponents:newComponents]; 

NSLog(@" \ndate : %@ \ntime : %@\ncomDate : %@",self.datePicker.date,self.timePicker.date,combDate);
