TimeZone Change causes Month shown to be wrong.

[Airtower]

If you set the Time zone to anything other than default, for ex. GMT. You can select back a month but as soon as you press forward a month with the arrow or a date into the next month, you get the slide transition to the current month forever.

If I get it right, the animation does not stop?
Does that happen to you in the sample?

[Airtower]

I'll check on the sample. The animation works except the months can only be decremented and never incremented (next month)

[Airtower]

I can't get the sample to work. The Swift version doesn't have a call for a timeZone change in it either. The OBJ-C version does but has issues with the pod file when I try to run it. I can't tell if this issue is isolated to my app or a bug. My app uses the OBJ-C version.

To clarify, the animation stops, problem is, it shows the same month as was shown before. If you go back, it shows the previous month but if you press "Next Month" it will show you the same month again.

I'm not using this control in any of my projects since a long time, that's why I'm not actively fixing it.
I've updated all the sample projects and now they should at least start and run. I did not experience this "going to the wrong month" animation so far

I'm having the same issue, if I set
[self.datePicker setDateTimeZoneWithName:@"UTC"];
the month doesn't change

Here's a quick video for you to check:

@hons82 any way I can help with this?

[Airtower]

Me too? Ive tried to fix it but can't seem to get it work on my end.

... sorry for the late reply, but I can't dedicate a lot of time to this project anymore...

Unfortunately I still can't reproduce this problem on my end. I did put it in the THCalendarDatePickerExample sample like that

- (IBAction)touchedButton:(id)sender {
    if(!self.datePicker)
        self.datePicker = [THDatePickerViewController datePicker];
    self.datePicker.date = self.curDate;
    self.datePicker.delegate = self;
    [self.datePicker setDateTimeZoneWithName:@"UTC"];
    [self.datePicker setAllowClearDate:NO];
    [self.datePicker setClearAsToday:YES];
    [self.datePicker setAutoCloseOnSelectDate:NO];
    [self.datePicker setAllowSelectionOfSelectedDate:YES];
    [self.datePicker setDisableYearSwitch:YES];
    [self.datePicker setDaysInHistorySelection:12];
    [self.datePicker setDaysInFutureSelection:0];
    [self.datePicker setSelectedBackgroundColor:[UIColor colorWithRed:125/255.0 green:208/255.0 blue:0/255.0 alpha:1.0]];
    [self.datePicker setCurrentDateColor:[UIColor colorWithRed:242/255.0 green:121/255.0 blue:53/255.0 alpha:1.0]];
    [self.datePicker setCurrentDateColorSelected:[UIColor yellowColor]];
    
    [self.datePicker setDateHasItemsCallback:^BOOL(NSDate *date) {
        int tmp = (arc4random() % 30)+1;
        return (tmp % 5 == 0);
    }];
    [self presentSemiViewController:self.datePicker withOptions:@{
                                                                  KNSemiModalOptionKeys.pushParentBack    : @(NO),
                                                                  KNSemiModalOptionKeys.animationDuration : @(1.0),
                                                                  KNSemiModalOptionKeys.shadowOpacity     : @(0.3),
                                                                  }];
}

and everything is working as expected...
