Nsdate Conversion返回Null

Question

我正在尝试将字符串转换为日期，但它返回null。

  NSString *offer_publishdate*=@"15/10/2013";
        NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
        [dateFormat setDateFormat:@"yyyyMMdd"];
        NSDate *date = [dateFormat dateFromString:offer_publishdate];
          NSLog(@"date:%@",date);

Answer 1

请选择确切的日期格式

 NSString *offer_publishdate*=@"15/10/2013";
    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"dd/MM/yyyy"];
    NSDate *date = [dateFormat dateFromString:offer_publishdate];
      NSLog(@"date:%@",date);

Answer 2

试试这种方式......

 NSString *offer_publishdate*=@"15/10/2013";
        NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
        [dateFormat setDateFormat:@"dd/MM/yyyy"];
        NSDate *date = [dateFormat dateFromString:offer_publishdate];

将日期格式化程序从@"yyyyMMdd更改为@"dd/MM/yyyy"
