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 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 basic app with a list view with manualy added cells.
How would i make it so that when a cell is clicked , a specific date is added to the iphone calendar?
Info - using latest xcode with storyboards
You should have a delegate for you list view that response to the UITableViewDelegate protocol. By tableView:didSelectRowAtIndexPath: you can catch the click to your cell.
Then, use EKEventStore class to access your calendar. Your appointment is represented by an EKEvent.
EDIT
For more information you should consult the Introduction to Calendars and Reminders, Event Kit Framework Reference, and Table View Programming Guide.
This is the general approach, for a more detailed description you should tell, what your issues are and what did you try. Nobody at SO will write the program for you.
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
Fixed labels in the selection bar of a UIPickerView
So XCode has been driving me crazy.. When writing iPhone apps using pickers or table views, when I state that the controller conforms to the DataSource and Delegate methods, XCode isn't generating code sense for those respective methods, and it's driving me nuts given how wordy some of them are..
Like -(NSInteger) tableView: (UITableView *) tableView indentationLevelForRowAtIndexPath: (NSIndexPath *) indexPath;
..I don't want to have to type that out every time I implement that. Is there a setting I've missed, or does XCode not dive into a protocol after you state you conform to it to generate code sense?
Not now, apparently.
I am looking into this right now. I am also baffled as to why there are not snippets for all the major delegate things you are going to use 10 ways to Sunday. I did a snippet recently for UITableViewDataSourceDelegate and that is very worthwhile. Wasted a bunch of time trying to get an Edit Menu to popup on a collection view cell last night that ended up being delegate methods in the docs not having the exact required syntax.
It is super clear how this should work. Two choices (not either/or, both should be supported):
As you say, I declare myself a delegate, I put in the - and start typing the method name, there should be a completion.
When Xcode notes that I have an incomplete implementation, in general, not just of delegates, it should have a quickfix to add stubs for chrissakes. That would take them no time to implement.
This is the last area in which eclipse really trounces Xcode. I don't understand the reluctance to just slam the door on this once and for all.
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.
