Help me to solve this issue.

Answer 1

-(NSDate *)getFirstDateOfCurrentYear
 {
  //Get current year
  NSDate *currentYear=[[NSDate alloc]init];
  currentYear=[NSDate date];
  NSDateFormatter *formatter1 = [[NSDateFormatter alloc] init];
  [formatter1 setDateFormat:@"yyyy"];
  NSString *currentYearString = [formatter1 stringFromDate:currentYear];

  //Get first date of current year
  NSString *firstDateString=[NSString stringWithFormat:@"10 01-01-%@",currentYearString];
  NSDateFormatter *formatter2 = [[NSDateFormatter alloc] init];
  [formatter2 setDateFormat:@"hh dd-MM-yyyy"];
  NSDate *firstDate = [[NSDate alloc]init];
  firstDate = [formatter2 dateFromString:firstDateString];

  return firstDate;
 }
