How to use one UIDatePicker for multiple UITextFields?

Question

In my viewDidLoad I have the following Code:

UIDatePicker* datePicker = [[UIDatePicker alloc] init];
datePicker.datePickerMode = UIDatePickerModeDate;
[datePicker addTarget:self action:@selector(datePickerChanged:) forControlEvents:UIControlEventValueChanged];
dateField1.inputView = datePicker;
dateField2.inputView = datePicker;
dateField3.inputView = datePicker;
dateField4.inputView = datePicker;

(The dateField's are all UITextFields)

In my -(void)datePickerChanged:(UIDatePicker*)datePicker method, how do I know which dateField is being edited, so that I can fill in the picked date?

Currently I am using a new UIDatePicker for each UITextField, but I hope there is a more elegant solution for this situation.

Any help is appreciated!

Answer 1

if([textField1 isFirstResponder]) {

}
else if[textField2 isFirstResponder]){

}

...etc...

You can set up different tags for your dateFields and check what field was changed in datePickerChanged: method. But to do it you should store original results in another place (for example in dictionary where your dateField's tags will be a keys). I did not tried this before but should work.
