Because there is a mass of question related to NSDate on SO and they all have the same shade, I will give you a longer answer, probably this can be referred from other questions. A. There is a common misunderstanding, what a date is: A date is a point on timeline. It does not deal … Read more
The 24-hour format is “HH”, not “hh”. The reason that it works in the Playground may be that user defined settings can override the 12/24-format choice, compare What is the best way to deal with the NSDateFormatter locale “feechur”?. To be on the safe side, set the “en_US_POSIX” locale for the date formatter: formatter.locale = … Read more
Duh!! Sometimes you have an “Aha!!” moment, sometimes it’s more of a “Duh!!” This is the latter. In the category for initWithSafeLocale the “super” init was coded as self = [super init];. This inits the SUPERCLASS of NSDateFormatter but does not init the NSDateFormatter object itself. Apparently when this initialization is skipped, setLocale “bounces off”, … Read more
I think you need to take a look at: + (NSString *)dateFormatFromTemplate:(NSString *)template options:(NSUInteger)opts locale:(NSLocale *)locale As per the docs: Returns a localized date format string representing the given date format components arranged appropriately for the specified locale. Return Value A localized date format string representing the date format components given in template, arranged appropriately … Read more
The reason for this behaviour is Locale, It sets the correct Locale. Set the local of your NSDateFormatter to en_US_POSIX will fix this. It works for both 24-hour and 12 hour format. On iPhone OS, the user can override the default AM/PM versus 24-hour time setting (via Settings > General > Date & Time > … Read more
This isn’t a problem with NSDateFormatter, it’s a change in how iOS 11 supports localization. Under iOS 11, [NSLocale currentLocale] only returns languages supported by your app’s localizations. If your app only supports English (as the base localization), then no matter what language the user selects on the device, currentLocale will always return English. Under … Read more
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
For simplicity I’m assuming that the dates you are formatting are all in the past (no “tomorrow” or “next week”). It’s not that it can’t be done but it would be more cases to deal with and more strings to return. You can use components:fromDate:toDate:options: with whatever combination of date components you are looking for … Read more
In Apple’s documentation they specified that in UIDatePickerModeDate. The DatePicker displays months, days of the month, and years. The exact order of these items depends on the locale setting. An example of this mode is [ November | 15 | 2007 ]. But In device it display as DD/MM/YYYY. See UIDatePicker for more info. So … Read more
I found out it works if you do it this way (see below). The key is using the method: – [NSDateFormatter getObjectValue:forString:range:error:] instead of -[NSDateFormatter dateFromString] The complete code: + (NSDate *)parseRFC3339Date:(NSString *)dateString { NSDateFormatter *rfc3339TimestampFormatterWithTimeZone = [[NSDateFormatter alloc] init]; [rfc3339TimestampFormatterWithTimeZone setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@”en_US_POSIX”] autorelease]]; [rfc3339TimestampFormatterWithTimeZone setDateFormat:@”yyyy-MM-dd’T’HH:mm:ssZ”]; NSDate *theDate = nil; NSError *error = nil; … Read more
