format a NSDate to DDMMYYYY?

问题

I have to send a DDMMYYY date from a Date to communicate with an API.

NSDateComponents *dateComponents; NSCalendar *gregorian; NSDate *date;

gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];

dateComponents = [[NSDateComponents alloc] init];
self.date = [gregorian dateByAddingComponents:dateComponents toDate:[NSDate date] options:0];

Do I have to use the [dateComponents day] and so on? is there some method that can help me to performing that task like in PHP?

Try this

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"ddMMyyyy"];
NSString *textDate = [NSString stringWithFormat:@"%@",[dateFormatter stringFromDate:[NSDate date]]];
NSLog(@"Date %@",textDate);
[dateFormatter release];

Just:

  NSDateFormatter *outputFormatter = [[NSDateFormatter alloc] init];
  [outputFormatter setDateFormat:@"ddMMyyyy"];
  NSString *textDate = [NSString stringWithFormat:@"%@",[outputFormatter stringFromDate:[NSDate date]]];
  [outputFormatter release];

Try this code:

NSDateFormatter* dateFormatter = [[[NSDateFormatter alloc] init] autorelease];
[dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_US_POSIX"] autorelease]];
[dateFormatter setDateFormat:@"ddMMyyyy"];
NSDate *current = [NSDate date];
NSString *currentstring = [dateFormatter stringFromDate:current]

Try this:

NSLog(@"%@", [dateFormatter stringFromDate:[NSDate date]]);

Agree With Ruben Esposito

Just change your code like this.

NSDateFormatter *dtFormatter = [[NSDateFormatter alloc]init];
[dtFormatter setDateFormat:@"ddMMyyyy"];    
NSString *strDate = [NSString stringWithFormat:@"%@",[dtFormatter stringFromDate:[NSDate date]]];
[dtFormatter release];
NSLog(@"%@",strDate);
