I need to get time in millisecond accuracy. How can I get it from NSDate . Currently when I NSLog time, it is showing only upto seconds. Jhaliya You'll need to use the below method to convert sec. into millisecond: ([NSDate timeIntervalSinceReferenceDate] * 1000) For those who want to get the time in mili seconds (like in Java) double timestamp = [[NSDate date] timeIntervalSince1970]; int64_t timeInMilisInt64 = (int64_t)(timestamp*1000); (tested with iOS7 and the iPhone simulator using Xcode 5) Kees is right about the milliseconds calculation, but you might want to consider processing only the

How would you get the date of the the first saturday that occurs after today in Objective-C for iOS?

In my app i'm using Facebook Graph API and when I'm fetching user details i get the user's birthday as a string with format MM/DD/YYYY. My question is, how can I convert string "MM/DD/YYYY" to NSDate ? I try doing NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"MM/DD/YYYY"]; NSDate *date = [dateFormatter dateFromString:@"08/08/2012"]; [dateFormatter release]; But I got the wrong date Using NSDateFormatter you can convert directly from a NSString to a NSDate .

I'm trying to format a date from a string into another format. For example: 2012-05-29 23:55:52 into 29/05 *newline* 2010 . I just don't get the logics behind NSDate and NSDateFormatter, I think.. Any help will be appreciated. Thanks :) You will need to create an NSDateFormatter, and then set it's dateFormat to match the first date you have, eg: NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"]; That will set your date formatter to recognise your date string. You can then obtain an NSDate object from this using NSDate *myDate

I'm trying to figure out what day (i.e. Monday, Friday...) of any given date (i.e. Jun 27th, 2009) Thank you. I've been doing: NSDateFormatter* theDateFormatter = [[[NSDateFormatter alloc] init] autorelease]; [theDateFormatter setFormatterBehavior:NSDateFormatterBehavior10_4]; [theDateFormatter setDateFormat:@"EEEE"]; NSString *weekDay = [theDateFormatter stringFromDate:[NSDate date]]; This has the added bonus of letting you choose how you'd like the weekday to be returned (by changing the date format string in the setDateFormat: call Lots more information at: http://developer.apple.com
