UIDatepicker's blue "today" label not changing

ansonl · 05-16-2011, 11:45 PM

Hey,

When the user might use an app w/ a date picker that shows date and time and then leave their device on overnight, the blue Today label in the date picker still stays on the previous day's date, not the new date.

Is there a way to clear the date picker and then send it a new date?

Code:

datepicker = nil; //I was thinking that this would reset the date picker settings
datePicker.date = [NSDate date];

^doesn't work, just sets the new time and date, but not the today label.

Code:

[datePicker setDate:[NSDate date] animated:NO];

Also,
Maybe try changing the datePickerMode to "reload" the data.

setDate doesn't work, it just sets the date. How would I get it to reload?

Hmm, doesn't seem to work, either. Still keeps the Today label on the previous date.

I guess removing the datepicker and recreating it would work, but another method would probably be much better.

So if you change it like so:

Code:

yourDatepicker.datePickerMode = UIDatePickerModeCountDownTimer;//Some random mode...
yourDatepicker.datePickerMode = UIDatePickerModeDateAndTime;//The mode you want...

It doesn't change

Yes, I used setDatePickerMode, but same thing.

No ideas, anybody?

use reloadAllComponents

ansonl · 05-18-2011, 11:01 PM

I'm trying this

Code:

[datePicker reloadAllComponents];

but the app freezes and says

Code:

-[UIDatePicker reloadAllComponents]: unrecognized selector sent to instance

This should be the right way to use it, right?

That is because UIDatePicker does not inherit from UIPicker. So that Method is not available on the UIDatepicker.

Your just gonna have to rebuild it I guess.

Try:

Code:

[datePicker reloadInputViews];

I wish it worked, but it didn't seem to do anything. Have you tried it successfully before? Maybe I just didn't do something right...
