I have a similiar but slightly more complex problem, and I’ve found a very simple solution! The problem: My incoming ISO8601 dates look like this: 2006-06-14T11:06:00+02:00 They have a timezone offset at the end. The solution: Use Peter Hosey’s ISO8601DateFormatter which you can download from here. ISO8601DateFormatter *formatter = [[ISO8601DateFormatter alloc] init]; NSDate *theDate = … Read more
func convertDateFormater(date: String) -> String { let dateFormatter = NSDateFormatter() dateFormatter.dateFormat = “yyyy-MM-dd’T’HH:mm:ss.SSSZ” dateFormatter.timeZone = NSTimeZone(name: “UTC”) guard let date = dateFormatter.dateFromString(date) else { assert(false, “no date from string”) return “” } dateFormatter.dateFormat = “yyyy MMM EEEE HH:mm” dateFormatter.timeZone = NSTimeZone(name: “UTC”) let timeStamp = dateFormatter.stringFromDate(date) return timeStamp } Edit for Swift 4 func convertDateFormatter(date: … Read more
When something like this is referred to as expensive, it doesn’t necessarily mean that you should never do it, it just means avoid doing it in situations when you need to get out of a method as quickly as possible. For example, back when the iPhone 3G was the latest device, I was writing an … Read more
You don’t need near as many single quotes as you have (only needed on non date/time characters), so change this: [self.dateFormatter setDateFormat:@”yyyy’-‘MM’-‘dd’T’HH’:’mm’:’ss’Z'”]; To this: [self.dateFormatter setDateFormat:@”yyyy-MM-dd’T’HH:mm:ssZZZ”]; … self.currentQuestion.updated = [self.dateFormatter dateFromString:[self.currentParsedCharacterData stringByReplacingOccurrencesOfString:@”:” withString:@”” options:0 range:NSMakeRange([self.currentParsedCharacterData length] – 5,5)]]; Documentation here: https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/DataFormatting/Articles/dfDateFormatting10_4.html#//apple_ref/doc/uid/TP40002369-SW1 Unicode Format Patterns: http://unicode.org/reports/tr35/tr35-6.html#Date_Format_Patterns Dealing with TimeZones with Colons (+00:00): http://petersteinberger.com/2010/05/nsdateformatter-and-0000-parsing/
You can convert unixTimestamp to date using Date(timeIntervalSince1970:). let unixTimestamp = 1480134638.0 let date = Date(timeIntervalSince1970: unixTimestamp) If you want to display date in string with specific formate than you can use DateFormatter like this way. let date = Date(timeIntervalSince1970: unixtimeInterval) let dateFormatter = DateFormatter() dateFormatter.timeZone = TimeZone(abbreviation: “GMT”) //Set timezone that you want dateFormatter.locale … Read more
YYYY is not the same as yyyy. According to this page which the iOS Date format page references; `y`: Year `Y`: Year (in “Week of Year” based calendars). This year designation is used in ISO year-week calendar as defined by ISO 8601, but can be used in non-Gregorian based calendar systems where week date processing … Read more
First, you need to convert your string to NSDate with its format. Then, you change the dateFormatter to your simple format and convert it back to a String. Swift 3 let dateString = “Thu, 22 Oct 2015 07:45:17 +0000” let dateFormatter = DateFormatter() dateFormatter.dateFormat = “EEE, dd MMM yyyy hh:mm:ss +zzzz” dateFormatter.locale = Locale.init(identifier: “en_GB”) … Read more
If your time format is in 24hrs please use “HH:mm:ss” format. Please test the code and let me know if it is working for you. I have tested and it is returning “4 PM” NSString *dats1 = @”16:00:00″; NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; [dateFormatter3 setDateStyle:NSDateFormatterMediumStyle]; [dateFormatter3 setDateFormat:@”HH:mm:ss”]; NSDate *date1 = [dateFormatter3 dateFromString:dats1]; NSLog(@”date1 … Read more
None of these answers were as aesthetically pleasing as what I’m using, so I thought I would share: Swift 3: func daySuffix(from date: Date) -> String { let calendar = Calendar.current let dayOfMonth = calendar.component(.day, from: date) switch dayOfMonth { case 1, 21, 31: return “st” case 2, 22: return “nd” case 3, 23: return … Read more
I don’t know what’s wrong with your code.But looks too much unnecessary things are there like you’re setting calendar, fetching some elements from string. Here is my small version of UTCToLocal and localToUTC function. But for that you need to pass string in specific format. Cause I’ve forcly unwrapped date objects. But you can use … Read more
