nsdate

My date string that I am getting is 2014-01-08T21:21:22.737+05:30 of this format. How do i confer it to NSDate? I tried: NSString *currentDateString = @"2014-01-08T21:21:22.737+05:30"; [dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss.SSS+05:30"]; NSDate *currentDate = [dateFormatter dateFromString:currentDateString]; NSLog(@"CurrentDate:%@", currentDate); It returns nil. Any thoughts? Use this code it is working fine your dateFormatter was wrong . NSDateFormatter *dateFormatter=[[NSDateFormatter alloc]init]; NSString *currentDateString = @"2014-01-08T21:21:22.737+05:30"; [dateFormatter

I'm using a NSDateFormatter to parse a RFC 822 date on the iPhone. However, there is no way to specify optional elements in the date format. There are a couple of optional parts in the RFC 822 specification which is breaking the date parser. If nothing works out, I'd probably have to write a custom parser to obey the specs. For example, the day name is optional in the spec. So both these dates are valid: Tue, 01 Dec 2009 08:48:25 +0000 is parsed with the format EEE, dd MMM yyyy HH:mm:ss z 01 Dec 2009 08:48:25 +0000 is parsed with the format dd MMM yyyy HH:mm:ss z This is what I am currently

This is a little more complicated then just NSPredicate *predicate = [NSPredicate predicateWithFormat:@"startDate >= %@ AND endDate <= %@", startDay,endDay]; I'm building a calendar app and I need to pull events out of my core data store that occur on a given day. However, it's possible for an event to start/end on a different day then the day I'm trying to display, e.g. My Date Range (Start = 2011-12-02 00:00:00 to End = 2011-12-02 23:59:59) An Event (Start = 2011-12-01 23:00:00 to End = 2011-12-02 05:00:00) How can I write a predicate to determine if that event falls in that date range. Keep

I'm trying to use the NSDate dateFromString method but I'm getting an warning and it's crashing the app. The code looks like: NSString *pickerDate = [NSString stringWithFormat:@"%@", timeSelector.date]; NSDate *defaultDate = [NSDate dateFromString:pickerDate]; The warning is: 'NSDate' may not respond to '+dateFromString'. It appears that method is deprecated (in the midst of an upgrade from XCode 2 to 3. What alternate method can I use to create a date from a string? NSDateFormatter is the intended way for you to get an NSDate from an NSString . The most basic usage is something like this:

I have got value from the xml 2009-11-23T05:24:41.000Z . Now i want to display string like this: Wed, Nov 4, 2009 8:00 PM - Wed, Nov 4, 2009 9:00 PM How it possible? You'll want to do something like this: NSDateFormatter * inputFormatter = [ [ [ NSDateFormatter alloc ] init ] autorelease ]; NSDateFormatter * outputFormatter = [ [ [ NSDateFormatter alloc ] init ] autorelease ]; [ inputFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss'.000Z'" ]; [ outputFormatter setDateFormat:@"EEE, MMM d, yyyy h:mm a" ]; NSString * inputString = @"2009-11-23T05:24:41.000Z"; NSDate * inputDate = [ inputFormatter

I need Objective C method for converting Gregorian date to Julian days same as this PHP method (GregorianToJD). According to http://en.wikipedia.org/wiki/Julian_day , the Julian day number for January 1, 2000, was 2,451,545. So you can compute the number of days between your date and this reference date. For example (Jan 1, 2014): NSUInteger julianDayFor01012000 = 2451545; NSCalendar *cal = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; [cal setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]]; NSDateComponents *comp = [[NSDateComponents alloc] init]; comp.year = 2014;

I generate a NSDate object from string. let dateFormatter = NSDateFormatter() dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss" dateFormatter.timeZone = NSTimeZone(abbreviation: "GMT") let stringToDate = dateFormatter.dateFromString(dateFromService) // 2015-07-20 12:00:43 +0000 I get this string value from webserver. I need to modify for personal device timezone. Want to add hours this stringToDate object but not work var addHours : Int = 2 // 2 hours will be added var newDate = stringToDate.dateByAddingTimeInterval(addHours) Duncan C You're asking the wrong question. This is what's known as an

NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; [formatter setDateFormat:@"hh:mm:ss a"]; NSLog(@"Today's Time: %@", [formatter stringFromDate:[NSDate date]]); The above code just gives the following output Today's Time: 15:46:43 I want the output to be Today's Time: 3:46 PM . I surfed a lot and i did not find a way to show AM/PM. Would be really helpful if someone can help me find a way out. I am using XCode 6.3 and my Device has iOS 8.3 installed in it. Check your device settings for 24 hour time. If it is on, turn it off. Your code is perfectly fine. I am getting output as shown
