Edit: This does not check the edge case where the beginning of the week starts in the prior month. Some updated code to cover this: https://stackoverflow.com/a/14688780/308315 In case anyone is still paying attention to this, you need to use ordinalityOfUnit:inUnit:forDate: and set firstWeekday to 2. (1 == Sunday and 7 == Saturday) Here’s the code: … Read more
Just add one day unit to the date until it reaches the current date (Swift 2 code): var date = startDateNSDate // first date let endDate = NSDate() // last date // Formatter for printing the date, adjust it according to your needs: let fmt = NSDateFormatter() fmt.dateFormat = “dd/MM/yyyy” // While date <= endDate … Read more
let now = Date() let dateFormatter = DateFormatter() dateFormatter.dateFormat = “LLLL” let nameOfMonth = dateFormatter.string(from: now)
Your statement The problem with the above method is that you can only set one unit of time … is not correct. NSCalendarUnit conforms to the RawOptionSetType protocol which inherits from BitwiseOperationsType. This means that the options can be bitwise combined with & and |. In Swift 2 (Xcode 7) this was changed again to … Read more
In Swift 5 there is a simple one-liner to get the number of days (or any other DateComponent) between two dates: let diffInDays = Calendar.current.dateComponents([.day], from: dateA, to: dateB).day Note: As pointed out in the comments, this solution measures the 24h periods and therefore requires at least 24h between dateA and dateB.
You can use the NSDate and NSCalendar classes: NSDate *today = [NSDate date]; //Get a date object for today’s date NSCalendar *c = [NSCalendar currentCalendar]; NSRange days = [c rangeOfUnit:NSDayCalendarUnit inUnit:NSMonthCalendarUnit forDate:today]; today is an NSDate object representing the current date; this can be used to work out the number of days in the current … Read more
@Chuck’s answer is correct, and lead me to the following code. Thought I’d share: NSDateComponents *comps = [[NSDateComponents alloc] init]; [comps setDay:10]; [comps setMonth:10]; [comps setYear:2010]; NSDate *date = [[NSCalendar currentCalendar] dateFromComponents:comps];
Swift 3/4/5: Calendar.current.isDateInToday(yourDate) Calendar.current.isDateInYesterday(yourDate) Calendar.current.isDateInTomorrow(yourDate) Additionally: Calendar.current.isDateInWeekend(yourDate) Note that for some countries weekend may be different than Saturday-Sunday, it depends on the calendar. You can also use autoupdatingCurrent instead of current calendar, which will track user updates. You use it the same way: Calendar.autoupdatingCurrent.isDateInToday(yourDate) Calendar is a type alias for the NSCalendar.
Swift 3 and 4 drop-in extensions This actually gets a lot easier with Swift 3+: You can do it without guard (you could if you wanted to, but because DateComponents is a non-optional type now, it’s no longer necessary). Using iOS 8’s startOfDayForDate (now startOfDay), you don’t need to manually set the time to 12pm … Read more
Swift 3 & 4 Retrieving the day of the week’s number is dramatically simplified in Swift 3 because DateComponents is no longer optional. Here it is as an extension: extension Date { func dayNumberOfWeek() -> Int? { return Calendar.current.dateComponents([.weekday], from: self).weekday } } // returns an integer from 1 – 7, with 1 being Sunday … Read more
