I have an NSArray of NSDate objects and I want to sort them so that today is at 0, yesterday at 1 etc. Is it ascending or descending, and do i use a function, selector or what? There are different sort methods for NSArray because there may be different ways you want to sort things. NSSortDescriptors are a general way that give you a lot of options as far as what keys to use in sorting, what selectors you want to use on those keys, and overall order to use, etc. Or you can use functions or comparator blocks instead if your case requires that or if that's more convenient for your particular case

How can I create an NSDate with today's date and an hour, minutes, and seconds of 5, 0, and 0 respectively? I.e. the date will be 07/02/2010 05:00:00 //Gives us the current date NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSDateComponents *components = [gregorian components:NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit fromDate:[NSDate date]]; [components setHour:5]; NSDate * date = [gregorian dateFromComponents:components]; [gregorian release]; Something along those lines should do the trick. 来源： https://stackoverflow.com

Suppose I have a simple String, extracted from an array of strings (representing dates) - var myDateString = "2015-11-25 04:31:32.0" Now, I want to convert it to a string that looks like Nov 25, 2015 . For that, I assume I need to - get a NSDate date object from string using NSDateFormatter get a string from that NSDate object by using some functionality (which I've been unable to find) I've been trying this in Playground, but have been unable to solve such a simple problem. Here is what I have tried - Line 1| var dateFormatter = NSDateFormatter() Line 2| dateFormatter.locale = NSLocale

In my iPhone app, I'd like to be able to determine if the user's locale's date format is Month/Day (i.e. 1/5 for January fifth) or Day/Month (i.e. 5/1 for January fifth). I have a custom NSDateFormatter which does not use one of the basic formats such as NSDateFormatterShortStyle (11/23/37). In an ideal world, I want to use NSDateFormatterShortStyle, but just not display the year (only month & day#). What's the best way to accomplish this? You want to use NSDateFormatter's +dateFormatFromTemplate:options:locale: Here is some Apple sample code: NSLocale *usLocale = [[NSLocale alloc]
