formatar um NSDate para DDMMYYYY?

Question

Tenho que enviar uma data DDMMAAA de uma Data para me comunicar com uma API.

NSDateComponents *dateComponents;NSCalendar *gregoriano;NSDate *data;

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

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

Tenho que usar o [dia de dateComponents] e assim por diante?existe algum método que possa me ajudar a realizar essa tarefa como no PHP?

Experimente

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

Apenas:

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

Concordar com Ruben Esposito

Basta alterar seu código assim.

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