Turning NSDate into NSString

Question

convert string to nsdate

Currently I have this code. It's for adding events to the calendar.

[...]
event.startDate = [[NSDate date] dateByAddingTimeInterval:86400];
event.endDate = [[NSDate date] dateByAddingTimeInterval:90000];

What I need is the code to add to a spesific start date and end date, and that's where NSString comes in handy. But I've had no luck converting it so far.

Refer this code :

NSString to NSDate

NSString *dateString = @"01-02-2010";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
// this is imporant - we set our input date format to match our input string
// if format doesn't match you'll get nil from your string, so be careful
[dateFormatter setDateFormat:@"dd-MM-yyyy"];
NSDate *dateFromString = [[NSDate alloc] init];
// voila!
dateFromString = [dateFormatter dateFromString:dateString];
[dateFormatter release];

NSDate convert to NSString:

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd-MM-yyyy"];
NSString *strDate = [dateFormatter stringFromDate:[NSDate date]];
NSLog(@"%@", strDate);
[dateFormatter release];

Hope it helps you

Thanks! How do I add it to the calendar though? (With regards to the code I previously posted) – GThaman Titan Jan 03 '13 at 14:59
@GThamanTitan : I guess you are already adding to event calendar, what do you want exactly? – P.J Jan 03 '13 at 15:00
What I meant is what should I write in the event.StartDate code now? (Instead of DateByAddingTimeInterval) – GThaman Titan Jan 03 '13 at 15:08
ok, so you are getting in NSString format and you want to convert it into NSDate, what is format of NSString you are getting, try NSLog it – P.J Jan 03 '13 at 15:10
I changed the code to event.startDate = [[NSDate date] dateFromString:@"dateString"]; and the app crashes. – GThaman Titan Jan 03 '13 at 15:14
are you familiar with ObjectiveC coding, what is value you are getting in dateString – P.J Jan 03 '13 at 15:18
check my above NSString to NSDate, just paste same code as it is, and also check if you are getting dateString value in format of dd-MM-yyyy – P.J Jan 03 '13 at 15:20
I'm a beginner to Objective-C. I set it to dateString because it refers to the date "01-02-2010". – GThaman Titan Jan 03 '13 at 15:20
NSLog dateString and tell me data you are getting there – P.J Jan 03 '13 at 15:21
This is the error I get: http://imgur.com/q5iD1 – GThaman Titan Jan 03 '13 at 15:29
just replace your crash code line with event.startDate = dateFromString; – P.J Jan 03 '13 at 15:34
Great thanks so much! But now the date is not correct, it adds the event tomorrow, not the date I specified. – GThaman Titan Jan 03 '13 at 15:36
You need to set locale of your calendar event properly, i.e. GMT – P.J Jan 03 '13 at 15:37

convert NSDate to NSString as

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateStyle:NSDateFormatterMediumStyle];

NSString *string = [dateFormatter stringFromDate:date];
[dateFormatter release];

That's an example if you need the format like “Nov 23, 1937”:

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateStyle= NSDateFormatterMediumStyle;
NSString* string= [formatter stringFromDate: date];

Check out the reference for other styles. If you need another style that hasn't a constant, you can use the date format, in this case it's:

formatter.dateFormat= @"MMM dd, yyyy"; // same as medium style

But the preferred way is to use the style, use the format only if there isn't a propert style.
