datepicker giving unrecognized selector error with UIControlEventValueChanged

I am writing a simple datepicker code for iphone but this one error is driving me crazy. Here are two use cases, one where it works and second where it doesn't:

  1. working case: When I select a date from picker and create a UIButton and calls the "-(IBAction)showdate:(id)sender" with "touch up inside" event of this button. showdate is a simple method which right now shows an alert of selected date.

  2. non-working case: When I call the same above mentioned method with "Value Changed" event of the picker I get following error: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFType showdate:]: unrecognized selector sent to instance

I have tried this with both Interface Builder as well as programmatically but getting similar results.

Could someone please tell me what am I missing here.

thanks,

Rols

You are doing wrong you cant call the IBAction with datePicker like this. For calling a function on value change event of date picker you dont need any button, Do like this.

Use this in your viewDidLoad- 

[self.datePicker addTarget:self
                            action:@selector(showdate:)
                  forControlEvents:UIControlEventValueChanged];

then write this function in your .m file. 

 -(void)showdate:(id)sender
    {
        //your code.
    }
