使用：

//懒加载-(DatePickerView *)datePickerView{    if(!_datePickerView){        _datePickerView = [DatePickerView new];        _datePickerView.delegate =self;        _datePickerView.datePicker.minimumDate = [NSDate date];    }    return _datePickerView;}//显示 如果设置默认日期可以这个 [self.datePickerView.datePicker setDate:[NSDate date]]; [self.datePickerView showDatePickerView];
