is there a way to set the UIDatepicker to minute and seconds versus Hour and Minute
edit I ended up adding my own UIPicker class, and creating the value and label myself.
I don't think there is any builtin way to do this in the SDK. Try just subclassing UIPickerView and you should end up with basically the same result.
If you search the help for UICatalog it has full examples of pickers and how to make you own custom picker.
There is no option to show minutes seconds according to the API documentation.

I need to create Custom UIDatePicker Control Displaying Only Days of week,Hours,Minutes and time Format(Am,Pm). I had just started iOS development so not having so much of idea.Any insights or reference appreciated. Thanks
Look at the datePickerMode property of UIDatePicker
The different available modes are :
typedef enum {
UIDatePickerModeTime,
UIDatePickerModeDate,
UIDatePickerModeDateAndTime,
UIDatePickerModeCountDownTimer
} UIDatePickerMode;
If you need days of week, you will need to implement a basic UIPickerView and add your own data on it.
You need to create your own customized pickers using UIPickerView. If we want to to use UIDatepicker,
Need to use date picker mode as UIDatePickerModeDateAndTime and we need to over shadow the other data which is not necessary.
I have a button in my view with the UIDatePickerModeCountDownTimer. How do I actually get it to start counting down? Examples would be fantastic.
You can create a datasource for you minute-seconds picker. It has two Components: minute and seconds. You have to implement some methods in UIPickerViewDelegate and UIPickerViewDataSource Protocols.
Apple's sample code UICatalog.app is for your reference. You can find there is a sample for how to create a customized picker.
I want to remove year from iOS date picker. Need to use in iPhone app.
This is down to the users phone localization settings... You'll need to create some sort of custom UIPicker if you want to make it the same for all.
Quick and easy way, create your UIPickerView with just two components.
You can't use the UIDatePicker because 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

hii there?
Can I make Date picker and Time picker in iphone separately.
If yes then plz give me some reference.
thanks in advance.
Yes. It's simple, you can set it through Interface builder itself.
I have a UIDatepicker created in UIBuilder and instantiated once when the app first loads. When first presented, the datepicker correctly flags today's date with the word 'Today'. On IOS 4, if I dismiss the app to the background, and reactivate it a day later, the date has advanced, but yesterdays date is still flagged as 'Today'. Explicitly updating the controls date has no effect. It looks like the control determines 'Today' only once, when created.
I've tried calling init to re-initialise it in-situ, but can't get that to work.
Am I missing something?
As a workaround for this bug you might catch the UIApplicationWillEnterForegroundNotification and dump and recreate the table cells to get a correct 'today' flag.
You can use UIDatePicker from Interface Builder. But when you return to the app you need to execute
[datePicker sizeToFit];
and it will updates "Today" cell.
The UIDatePicker shows the default value from your Interface Builder setting. I added UIDatePicker in viewDidLoad{} but not in Interface Builder, it works well.
