Is there an easy way to init an NSDate with the current UTC date/time?
766
timeZone = [NSTimeZone timeZoneForSecondsFromGMT:0]; //Create a date string in the local timezone dateFormatter. timeZone = [NSTimeZone timeZoneForSecondsFromGMT:[NSTimeZone localTimeZone]. secondsFromGMT]; NSString *localDateString = [dateFormatter stringFromDate:[NSDate date]]; NSLog(@"date = %@", localDateString);
In this article i'll show you how to do some common tasks with the NSDate object. Get Today's Date: NSDate* date = [NSDate date];
Use DateFormatter to parse and format a date in Swift. The default time zone for a DateFormatter is the device's local time, so to obtain UTC time the timeZone value needs to be configured.
NSDate objects encapsulate a single point in time, independent of any particular calendrical system or time zone. Date objects are immutable, representing an invariant time interval relative to an absolute reference date (00:00:00 UTC on 1 January 2001).
[NSDate date];
You may want to create a category that does something like this:
-(NSString *)getUTCFormateDate:(NSDate *)localDate { NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"UTC"]; [dateFormatter setTimeZone:timeZone]; [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"]; NSString *dateString = [dateFormatter stringFromDate:localDate]; [dateFormatter release]; return dateString; } NSDate is a reference to an interval from an absolute reference date, January 1, 2001 00:00 GMT. So the class method [NSDate date] will return a representation of that interval. To present that data in a textual format in UTC, just use the NSDateFormatter with the appropriate NSTimeZone (UTC) to render as needed.
