Question

任何人解决我从网络服务获得日期和时间匹配的问题，但我需要在日期选择器中编辑单独的时间...我需要设置最大时间和最短时间。

这是我的代码

- (IBAction)EndBreak_btn:(id)sender {


  //  _text_EndBreak.text=_MATCHDATE;
    [_datePicker_View setHidden:NO];
    [_date_picker setHidden:YES];
     [_date_picker1 setHidden:NO];
    _date_picker1.datePickerMode = UIDatePickerModeTime;
    [_date_picker1 addTarget:self
                     action:@selector(BreakEnd:)forControlEvents:UIControlEventValueChanged];

}

-(void)BreakEnd:(id)sender
{

    NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"hh:mm:ss"];
    NSDate *date = [dateFormat dateFromString:_MATCHDATE];
      [dateFormat setDateFormat:@"hh:mm:ss"];
    [_date_picker1 setDate:date];
   //[_date_picker1 setMinimumDate:date];


    NSString *Time = [dateFormat stringFromDate:date];
    BREAKENDTIME =[NSString stringWithFormat:@"%@ %@" ,[_text_EndBreak text],Time];

}

我在时间选择器中单独显示时间但是当我选择它因为MatchDate字符串是Nill而崩溃时...我无法从MatchDateString单独转换时间在此先感谢

使用

NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
                            2016-06-25 12:00:00
[dateFormat setDateFormat:@"yyyy-MM-dd hh:mm:ss"];
NSDate *date = [dateFormat dateFromString:_MATCHDATE];
  [dateFormat setDateFormat:@"hh:mm:ss"];

// for minimum date
[_date_picker1 setMinimumDate:date];

// for maximumDate
int daysToAdd = 2;
NSDate *newDate1 = [date dateByAddingTimeInterval:60*60*24*daysToAdd];

 [_date_picker1 setMaximumDate:newDate1];



 NSString *Time = [dateFormat stringFromDate:date];
BREAKENDTIME =[NSString stringWithFormat:@"%@ %@" ,[_text_EndBreak text],Time];

在日期选择器中显示时间设置最大时间和最短时间
