UUDatePikcer_Max_Min

UUDatePicker have four style to select:
-

    UUDateStyle_YearMonthDayHourMinute,
    UUDateStyle_YearMonthDay,
    UUDateStyle_MonthDayHourMinute,
    UUDateStyle_HourMinute

and you need to add it's delegate method or used by block:
-
- (id)initWithframe:(CGRect)frame PickerStyle:(DateStyle)uuDateStyle didSelected:(FinishBlock)finishBlock;
        
        UUDatePicker *datePicker= [[UUDatePicker alloc]initWithframe:CGRectMake(0, 0, 320, 200)
                                 PickerStyle:a[i]
                                 didSelected:^(NSString *year,
                                               NSString *month,
                                               NSString *day,
                                               NSString *hour,
                                               NSString *minute,
                                               NSString *weekDay) {
                                     //nslog
                                 }];

#pragma mark - UUDatePicker's delegate
- (id)initWithframe:(CGRect)frame Delegate:(id<UUDatePickerDelegate>)delegate PickerStyle:(DateStyle)uuDateStyle;


 - (void)uuDatePicker:(UUDatePicker *)datePicker
                year:(NSString *)year
               month:(NSString *)month
                 day:(NSString *)day
                hour:(NSString *)hour
              minute:(NSString *)minute
             weekDay:(NSString *)weekDay

if you want to choose datePikcer's range or make picker scroll to specified time, you can do like this:
-

    UUDatePicker *datePicker= [[UUDatePicker alloc]initWithframe:CGRectMake(0, 0, 320, 200)
                                                        Delegate:self
                                                     PickerStyle:UUDateStyle_YearMonthDayHourMinute];
    NSDate *now = [NSDate date];
    
    //scroll to specified time
    datePicker.ScrollToDate = now;
    
    //select the max limit time
    datePicker.maxLimitDate = now;
    
    //select the max limit time
    datePicker.minLimitDate = [now dateByAddingTimeInterval:-1110000];
    
    textfield.inputView = datePicker;

anyway, the code still has many deficiencies need your participation to make it perfect.
