UIDatePicker with UIToolbar - ios

Question

I'm trying to implement UIToolbar on UIDatepicker to dismiss it when touching "Done" button. But when I tap on the button, the datepicker is scrolling and the action button doesn't work.
Here is my code :
datepicker = [[UIDatePicker alloc] initWithFrame:CGRectZero];
[datepicker setDatePickerMode:UIDatePickerModeDate];
[datepicker addTarget:self action:#selector(changeDate:) forControlEvents:UIControlEventValueChanged];
UIToolbar *toolbar= [[UIToolbar alloc] initWithFrame:CGRectMake(0,0,self.view.frame.size.width,44)];
toolbar.barStyle = UIBarStyleDefault;
UIBarButtonItem *flexibleSpaceLeft = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem* doneButton = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(dismiss)];
[toolbar setItems:[NSArray arrayWithObjects:flexibleSpaceLeft, doneButton, nil]];
[datepicker addSubview:toolbar];
My datepicker :
Thank you for your help.

Answer 1

If you use UITextField set
textField.inputAccessoryView = toolbar;
textField.inputView = datepicker;

Answer 2

You have to set inputAccessoryView and InputView to to your UITextField
txtField.inputAccessoryView = toolBar;
txtField.inputView = datePickerView;

Answer 3

remove this line from your code:
[datepicker addSubview:toolbar];
and add dismiss method nd add
txtCurrent.inputAccessoryView = toolbar; in didbeginEditing.
-(void)textFieldDidBeginEditing:(UITextField *)textField {
txtCurrent = textField;
[datePicker setHidden:NO];
txtCurrent.inputAccessoryView = toolbar;
if ([textField.text isEqualToString:#""]) {
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
NSDate *eventDate = [NSDate date];
[dateFormat setDateFormat:#"MM/dd/yyyy"];
NSString *dateString = [dateFormat stringFromDate:eventDate];
textField.text = [NSString stringWithFormat:#"%#",dateString];
}
[textField setInputView:datePicker];
}
-(void)dismiss{
datePicker.hidden = YES;
[self.view endEditing:YES];
}

Try this [self.view addSubview:toolbar];
picker = [[UIDatePicker alloc] init];
picker.autoresizingMask = UIViewAutoresizingFlexibleWidth;
picker.datePickerMode = UIDatePickerModeTime;
[picker addTarget:self action:#selector(dueDateChanged:) forControlEvents:UIControlEventValueChanged];
//CGSize pickerSize = [picker sizeThatFits:CGSizeZero];
picker.frame = CGRectMake(0.0, self.view.frame.size.height - 250, self.view.frame.size.width, 250);
picker.backgroundColor = [UIColor whiteColor];
toolbar= [[UIToolbar alloc] initWithFrame:CGRectMake(0,self.view.frame.size.height - 294,self.view.frame.size.width,44)];
toolbar.barStyle = UIBarStyleDefault;
UIBarButtonItem *flexibleSpaceLeft = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIButton* infoButton = [UIButton buttonWithType: UIButtonTypeInfoLight];
[infoButton addTarget:self action:#selector(dismiss) forControlEvents:UIControlEventTouchDown];
UIBarButtonItem* doneButton =[[UIBarButtonItem alloc]initWithCustomView:infoButton];
[toolbar setItems:[NSArray arrayWithObjects:flexibleSpaceLeft, doneButton, nil]];
[self.view addSubview:toolbar];
[self.view addSubview:picker];
