NSDateFormatter dateFormat ShortStyle not working

ios,iphone,swift,xcode6,nsdateformatter

My friend looked at the code and point out the problem. This problem is caused by the differences of the date format between Chinese/Japanese and English. In Chinese/Japanese, the date format is year/month/date. But in English, the date format is month/date/year. In my code, I set the dateStyle into ShortStyle...

NSDateFormatter dateFromString return wrong year

ios,objective-c,ios8,nsdateformatter,ios7.1

The issue is the locale of the formatter. If you want to use gregorian calendar regardless of the device settings, you generally should set locale to en_US_POSIX. formatter.locale = [NSLocale localeWithLocaleIdentifier:@"en_US_POSIX"]; See Apple Technical Q&A #1480.

nsdateformatter

Surely you could just use substringFromIndex on the string, something that should work for the next eight thousand years or so (a). In other words, something like: self.julian.text = [[julianFormatter stringFromDate:julianLabel] substringFromIndex:3]; (a) It'll work as per your specification until we reach the year 10,000 but keep in mind you'll...

Swift date formatting with NSDateFormatter

ios,xcode,nsdateformatter

let dateShow = formatter.dateFromString(v["feedDate"].description) I would first check if v["feedDate"] isn't an optional, because in this case the v["feedDate"].description would probably contain string like Optional("2015-05-10T18:39:55+02:00") as opposed to 2015-05-10T18:39:55+02:00, which obviously won't get converted to NSDate...

Converting A NSDate Array to a String Array in Swift

string,swift,parse.com,nsdateformatter

This is a highly inefficient way of formatting the dates into a String since it instantiates a new NSDateFormatter each time.

Swift - convert date string from a “datepicker filled date field” to nsdate

swift,nsdate,nsdateformatter,uidatepicker

I think I've fixed it. I think the thing that was causing problem was that I was setting locale to currentLocale but then 2 lines down specifying a dateFormat which would work if it corresponds to the current locale but not otherwise. Anyway, fix appears to be just specify locale...

Swift: can't get NSDate dateFormatter right

ios,date,swift,nsdate,nsdateformatter

It looks like your date formatter is a bit off. "MM'/'DD'/'YYYY" reads "Padded month / day of the year (not month) / year of the current week (so Jan 1-6 could overlap and add side-effects)" I'm guessing that what you're aiming for is "MM'/'dd'/'yyyy", which reads "Padded month / padded...

Swift: Result of dateFromString nil unexpectely

Remove the line with the NSDateFormatterStyle: let dateFormatter = NSDateFormatter() dateFormatter.dateFormat = "dd.MM.yyyy HH:mm" dateFormatter.locale = NSLocale(localeIdentifier: "en_US_POSIX") let timestamp = dateFormatter.dateFromString("07.07.2015 19:07") This is because setting an NSDateFormatterStyle overrides dateFormatter.dateFormat, making the results nil when using both. The solution is to not use NSDateFormatterStyle if you already have a...

It all comes down to knowing your format code strings. You are misusing "HH" here so the hour is coming out wrong. Another problem is that you are not capturing the error.

Setting dateStyle or timeStyle will override any custom dateFormat you have set.

It's due the difference between your timezone and UTC. The value 2029-12-31T00:00:00+00:00 is on December 31 in the UTC timezone. But when you setup the date components you are getting back the date in your timezone where it's December 30 local time.

How do I change the displayed time format after NSTimer is initiated?

ios,objective-c,nstimer,nsdateformatter

The problem is that you have two different updateTimers -- self.updateTimer the class variable and updateTimer the local variable. You're invalidating the class variable, but initializing and running multiple local NSTimers with different locales during each call to startTimer. That's why you see this "flickering" -- it's because multiple NSTimers...

I'm not sure why you expect that the dateFormat changes if the date changes significantly. The significant time change event is triggered when the time (i.e. [NSDate date]) changes.

Converting NSDate to NSString and back won't return the same date

ios,ios8,nsdate,nsdateformatter

The problem is that you lose the sub-second accuracy in conversion. When creating [NSDate now], the sub-second information is kept in NSDate object.
