ios – 如何在UIDatePicker中禁用未来的日期,月份和年份？

@H_419_1@如何隐藏UIDatePicker中的未来日期,以便用户只选择过去和当前的生日.

我搜索很多来源,但我无法获得所需的结果.

这是我的代码,

dateofBirthDatePicker = [[UIDatePicker alloc] initWithFrame:CGRectMake(0.0,44.0,0.0,0.0)];

    dateofBirthDatePicker.datePickerMode = UIDatePickerModeDate;
    [dateofBirthDatePicker setBackgroundColor:DATE_PICKER_GRAY_COLOR];

//    UILabel *label = [UILabel appearanceWhenContainedIn:[UITableView class],[UIDatePicker class],nil];
//    label.font = HELVETICA_NEUE(24);
//    label.textColor = GREEN_COLOR;
    [dateofBirthDatePicker addTarget:self
                              action:@selector(LabelChange:)
                    forControlEvents:UIControlEventValueChanged];
    dateofbirthTextField.inputView = dateofBirthDatePicker;
    [self datePickerToolBar];
}

- (void)LabelChange:(id)sender
{
    NSDateFormatter *dateFormat= [[NSDateFormatter alloc] init];
    [dateFormat setDateFormat:@"dd/MM/yyyy"];
    dateofbirthTextField.text = [NSString stringWithFormat:@"%@",[dateFormat stringFromDate:dateofBirthDatePicker.date]];
}

如果任何身体知道解决方案,请给出建议.我真的很感激你

dateofBirthDatePicker.maximumDate=[NSDate date];
