nsdateformatter

I am able to display the current time on my iPad application using the code, NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setTimeStyle: NSDateFormatterShortStyle]; NSString *currentTime = [dateFormatter stringFromDate: [NSDate date]]; timeLabel.text = currentTime; But this gives the time only when the application is loaded. How do i get the time to keep running? Like a digital clock. Use this: NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setTimeStyle: NSDateFormatterShortStyle]; [NSTimer scheduledTimerWithTimeInterval:1.0

I want to know which is this date format Friday, December 18th and also is this standard date format or i have to some hard work to get this. Thanks. I don't think the th is possible to achieve via formatters. Although you can do it like this: NSDate *today = [NSDate date]; NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init]; [dateFormat setDateFormat:@"EEEE, MMMM d"]; NSString *dateString = [dateFormat stringFromDate:today]; NSCalendar *cal = [NSCalendar currentCalendar]; unsigned unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit; NSDateComponents *dtComp =

//NSString *compileDate = [NSString stringWithFormat:@"%s", __DATE__]; NSString *compileDate = [NSString stringWithUTF8String:__DATE__]; NSDateFormatter *df = [[[NSDateFormatter alloc] init] autorelease]; [df setDateFormat:@"MMM d yyyy"]; //[df setDateFormat:@"MMM dd yyyy"]; NSDate *aDate = [df dateFromString:compileDate]; Ok, I give up. Why would aDate sometimes return as nil? Should it matter if I use the commented-out lines... or their matching replacement lines? It can return nil if the phone's Region setting is not US (or equivalent). Try setting the formatter's locale to en_US: NSString

I have an array of NSDate objects that I'm trying to convert to a string . My way of converting them is with NSDateFormat , but, if there's another better way, I'd be happy to hear. The most things a date would have is: Days-Hours-Minutes-Seconds-Milliseconds But some will have less, like: Minutes-Seconds-Milliseconds Or even less. Now I will have to convert them to a string . Would I have to create if statements to determine if it has days, hours, and so on, or is there an easier way of doing this? Example using NSDataDetector (Swift 2.0): let textDate = "dan's march 31, 1975 12:34 pm"; do {

Question Why is string nil? let formatter = NSDateComponentsFormatter() let referenceDate = NSDate(timeIntervalSinceReferenceDate: 0) let intervalDate = NSDate(timeInterval: 3628810, sinceDate: referenceDate) let string = formatter.stringFromDate(referenceDate, toDate: intervalDate) I'm expecting a string like "6w 10s" to be returned. (6 weeks is 3,628,800 seconds.) Attempted Troubleshooting To troubleshoot, I tried setting allowedUnits : formatter.allowedUnits = .YearCalendarUnit | .MonthCalendarUnit | .WeekCalendarUnit | .DayCalendarUnit | .HourCalendarUnit | .MinuteCalendarUnit |
