I'd like to have a UIDatePicker where the user can pick a month and a day but not the year. I'm aware that leap years have an extra day, so for simplicity, let's throw that day away.
Is there any way to remove the year column or have 2 reels with month/day that act like the UIDatePicker (grey out days that don't exist in the selected month)?
You cannot use the UIDatePicker class as it stands to do this - The UIDatePicker only supports the following modes
typedef enum {
UIDatePickerModeTime,
UIDatePickerModeDate,
UIDatePickerModeDateAndTime,
UIDatePickerModeCountDownTimer
} UIDatePickerMode;
Create a view and controller that implement the UIPickerViewDelegate and create your own - you may find a little more detail here Fixed labels in the selection bar of a UIPickerView

Is there a way to display the day of week (short or long) in the picker itself? I've seen examples of this value getting calculated but I've found nothing that shows a picker that resembles to IOS one where the left most wheel shows the day of the week AND the day of the month...
You can do it with the dateOrder option, where you would need to pass: 'mmD ddy'
It will look something like
$('#demo').mobiscroll().date({
// your inti properties
dateOrder: 'mmD ddy'
});
i have a functionility for show count down timer in format, but when uidatepicker in count down timer mode , it show only HH:MM.
how i can add a extra field for second in uidatepickerview.

You can't. UIDatePicker only displays hours and minutes in countdown mode. If you need to display seconds as well, you'll have to recreate it yourself using a UIPickerView.
As always, you should file an enhancement request to request this functionality.
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView;
{
return 2;
}
it will create section in your picker view.
The default UIDatePicker shows both the date and time. I need to show only the month, day, year and time like this
How can I change the date picker to this?
Well First off I suggest reading through the UIDatePicker documentation. Here are the Date Picker Modes:
Date Picker Mode
The mode of the date picker.
typedef enum {
UIDatePickerModeTime,
UIDatePickerModeDate,
UIDatePickerModeDateAndTime,
UIDatePickerModeCountDownTimer
} UIDatePickerMode;
If you cannot find what you need there. Then you can create your own by using a UIPickerView.
Any idea on how to customize the UIDatePicker with single column with list of events in it,and user should be able to select one among it ? Let me know some details about it. or example related to it.
Thank You
In code:
UIDatePicker has the datePickerMode property exactly for this reason.
You can set it with UIDatePickerModeTime.
In Interface Builder:
The top property in Date Picker Attributes window is Mode - choose Time.
You can use any of these
UIDatePickerModeDate, // Displays month, day, and year depending on the locale setting (e.g. November | 15 | 2007)
UIDatePickerModeDateAndTime, // Displays date, hour, minute, and optionally AM/PM designation depending on the locale setting (e.g. Wed Nov 15 | 6 | 53 | PM)
Like this
datePicker.datePickerMode = UIDatePickerModeDateAndTime;
I'm getting crashes from my UIDatePicker view and I think it's because I'm not retaining the pickers selected date. Can anyone tell me if this could be correct?
I have a modal view for selecting a toDate and a fromDate range. These values are passed into the modal view and grabbed out of the view when it's dismissed.
The view has one UIDatePicker and a segmented button for switching between the to and from dates.
Every time the segmented control switches I set the pickers date to the matching to or from date. When the picker value changes I update the to or from dates accordingly. The view crashes after a couple of switches between these dates.
I'm not retaining the pickers selected date so I'm guessing when I set the value of the pickers date from the toDate to the fromDate the toDate is being released so when I switch the picker back to the toDate it's going to crash.
Also to use the selected date from the picker outside the view will the date need to be retained as the picker will be released along with the date?
Does this make sense to anyone?
If you need to grab the date value from a UIDatePicker, you indeed need to retain a copy if you'll be using it outside the scope of the function (say, over multiple AutoreleasePool cycles).
Getting the date from a UIDatePicker will retain a reference but it will be autoreleased so effectively is only valid until the autorelease pool is destroyed.
Remember to release your reference once you've finished with it.
For simply using it temporarily inside a function, you won't need to retain it as stated above.
Why don't you set a property of your viewvcontroller or other class to the date you get using:
self.date = date;
Define date to be a #property with a retain attribute. That way you should be able to use date in other places of your app, and it won't be autoreleased when you go through the runloop.
