ios - 将 NSDate 格式化为 DDMMYYYY？

Question

我必须从 Date 发送 DDMMYYY 日期才能与 API 通信。

NSDateComponents *dateComponents; NSCalendar *gregorian; NSDate *日期；

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

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

我必须使用 [dateComponents day] 等吗？是否有一些方法可以帮助我像在 PHP 中那样执行该任务？

Answer 1

试试这个

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

Answer 2

只是：

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

Answer 3

试试这个代码：

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]

只需像这样更改您的代码。

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