How to convert datetime format to NSString?

Question

I have a value from xml 2009-11-23T05:24:41.000Z.

Now I want to display the line as follows: Wed, Nov 4, 2009 8:00 PM - Wed, Nov 4, 2009 9:00 PM

How is this possible?

Answer 1

You need to do something like this:

NSDateFormatter * inputFormatter = [ [ [ NSDateFormatter alloc ] init ] autorelease ];
NSDateFormatter * outputFormatter = [ [ [ NSDateFormatter alloc ] init ] autorelease ];
[ inputFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss'.000Z'" ];
[ outputFormatter setDateFormat:@"EEE, MMM d, yyyy h:mm a" ]; 

NSString * inputString = @"2009-11-23T05:24:41.000Z";
NSDate * inputDate = [ inputFormatter dateFromString:inputString ];
NSString * outputString = [ outputFormatter stringFromDate:inputDate ];

// outputString = @"Mon, Nov 23, 2009 05:24 AM"

For more information on customization, NSDateFormattersee the Unicode Date Format Template Guide .

Answer 2

Use methods NSDateFormatter -dateFromString:and -stringFromDate:.
