I'm using Date Picker, which is set to Count Down Timer mode. By default it displays the current time. How would I set it to display a specific time on start up? Thanks in advance.
You can use date property
UIDatePicker > date
Use this property to get and set the currently selected date

I am trying to set the initial scroll position as I have a floating search bar that will sit above my calendar.
Here is what it looks like on load as you can see the initial date is hidden:
Here is what I want it to look like on start as you can see the initial date is just below my floating search bar:
Anyone know how I can achieve this? Setting the initial start date 1/2 days behind is not an option as the height will vary based on the number of events in those days.
As per the current implementation of the calendar, there is no support to change the initial scroll position. The calendar will be positioned as the initial date view based on the initial display date value or controller display date value.

I am playing with a UIDatePicker in my project and I have decided to change the text color to white with
self.datePicker.setValue(UIColor.white, forKey: "textColor")
I also have a minimum date set to today's date. The issue I am having is that the date and time text outside of my minimum date is still grey making it hard to see on my screen. I have been browsing the documentation and am not able to find a list of what key value pairs are available to the class in order to fix this. Thanks.
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.
hi guys can any body help me to figure out that how i can restrict the minimum date in UIDatePickerView? i tried to set property minumumDate from xib file but it is not working, even i set the the mode like this
[datePicker setDatePickerMode:UIDatePickerModeCountDownTimer];
but still it is not working. what i want to do is that user cannot scroll down from a specific date. example: if restricted date is 21.11.2011 then user should not scroll it to less then this date so please help me to figure it out
Thanx in advance
I think you would want to set the mode to 'UIDatePickerDate', as 'UIDatePickerCountDownTimer' is meant to display a time. Have you tried:
[datePicker setDatePickerMode:UIDatePickerModeDate];
[datePicker setMinimumDate:minDate];
minDate would be an NSDate with the restricted date. For info on how to initialize this date, see here in the Apple documentation. Especially the part about date components.
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.
