nsdatecomponents

I'm writing a GTD app for the iPhone. For the due tasks, I want to display something like "Due tomorrow" or "Due yesterday" or "Due July 18th". Obviously, I need to display "Tomorrow" even if the task is less than 24 hours away (e.g. the user checks at 11pm on Saturday and sees there's a task on Sunday at 8am). So, I wrote a method to get the number of days in between two dates. Here's the code... NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"yyyy-MM-dd-HH-mm"]; NSDate *nowDate = [dateFormatter dateFromString:@"2010-01-01-15-00"]; NSDate

How do I get the NSDateComponents of a single NSDate? I don't want the components of the difference between 2 dates, just the seconds, minutes, hours, day, month and year of a NSDate? There's an example in the Apple docs , Listing 3: Getting a date’s components : NSDate *today = [NSDate date]; NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSDateComponents *weekdayComponents = [gregorian components:(NSDayCalendarUnit | NSWeekdayCalendarUnit) fromDate:today]; NSInteger day = [weekdayComponents day]; NSInteger weekday = [weekdayComponents weekday];

I am expecting 2010-10-11 00:00:00 But instead I receive 2010-10-10 21:00:00 +0000 I know, that I can add a few hours and receive desired date, but I do not understand why I get previous day with 21 hours... Please, help! NSDateComponents *comps = [[NSDateComponents alloc] init]; [comps setYear:2010]; [comps setMonth:10]; [comps setDay:11]; [comps setHour:0]; [comps setMinute:0]; [comps setSecond:0]; NSCalendar *cal = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSDate *retDate = [cal dateFromComponents:comps]; KingofBliss I think your problem may be solved by setting

I'm trying to figure out what day (i.e. Monday, Friday...) of any given date (i.e. Jun 27th, 2009) Thank you. I've been doing: NSDateFormatter* theDateFormatter = [[[NSDateFormatter alloc] init] autorelease]; [theDateFormatter setFormatterBehavior:NSDateFormatterBehavior10_4]; [theDateFormatter setDateFormat:@"EEEE"]; NSString *weekDay = [theDateFormatter stringFromDate:[NSDate date]]; This has the added bonus of letting you choose how you'd like the weekday to be returned (by changing the date format string in the setDateFormat: call Lots more information at: http://developer.apple.com

This question already has an answer here: How to compare two dates in Objective-C 14 answers Is date1 == date2 not a valid way to compare? If not, what is the correct alternative? Here's my code: - (NSDate*) dateWithNoTime { unsigned int flags = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit; NSCalendar* calendar = [NSCalendar currentCalendar]; NSDateComponents* components = [calendar components:flags fromDate:self]; NSDate* dateOnly = [calendar dateFromComponents:components]; return dateOnly; } - (BOOL) sameDayAsDate:(NSDate*)dateToCompare { NSDate *date1 = [self dateWithNoTime]

how do I set an existing NSDate 's time? That is I have a date (say current date/time), but then want to set this to a specific time (e.g. 11.23am) say. What is the quickest way to do this in objective C? I'm looking at NSCalendar and see methods such as dateByAddingComponents:toDate:options: , and dateFromComponents: , but these don't seem to quite hit the mark for what I need here. For example: dateFromComponents: - I would have to work out all components for this to work which seems like overkill dateByAddingComponents:toDate:options: - I don't want to ADD in my case but rather "set" the

I want to convert server UTC time to local time and vice-versa. Here is my code.. var isTimeFromServer = true var time:String! var period:String! let timeString = "6:59 AM" //Current UTC time if isTimeFromServer { let index = timeString.index(timeString.startIndex, offsetBy: 5) let twelve = timeString.substring(to: index) var dateString:String! let dateFormatter = DateFormatter() dateFormatter.dateFormat = "H:mm" let date12 = dateFormatter.date(from: twelve)! dateFormatter.dateFormat = "h:mm a" let date22 = dateFormatter.string(from: date12) //print(date22) dateString = date22 //print(
