Answer 1

I'm giving you the answer, but downvoting your question for being too elementary and whose solution could easily found with a simple search.

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"MM/dd/yyyy hh:mm:ss a"];
NSDate *date = [formatter dateFromString:myDateString];
[formatter setDateFormat:@"dd MMMM yyyy aa:mm:ss a"];
NSString *newDate = [formatter stringFromDate:date];

Answer 2

NSString *dateStr = @"12/31/2013 09:12:15 AM";

// Convert string to date object
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"MM/dd/yyyy hh:mm:ss a"];
NSDate *date = [dateFormat dateFromString:dateStr];  

// Convert date object to desired output format
[dateFormat setDateFormat:@"EEEE MMMM d, YYYY"];
dateStr = [dateFormat stringFromDate:date];  
[dateFormat release];
