UIDatePicker Selected value is wrong in case UIDatePicker was not scrolled

enter image description here

I am making an iPhone app in which I am using UIDatePicker and displaying the selected the time in a actionsheet. In actionsheet the time is displaying with 10 mints interval.

textfield value is set correctly when I do scroll the Datepicker

If I don't scroll the action sheet then direct click on select button then text field set the current time (11:56) but I select in action sheet (11:50) time. (textfield) shows the incorrect value.

How can I set the textfield's value (11:50). Give me some solution.

I dont know this way correct wrong but its working for me

-(void)selectedTime{
    NSDateFormatter *outputFormatter = [[NSDateFormatter alloc] init];
//    [outputFormatter setDateFormat:@"h:mm a"];
    [outputFormatter setDateFormat:@"HH:mm:ss"];
    selectedTime = [outputFormatter stringFromDate:datePicker.date];
    NSArray *temp=[selectedTime componentsSeparatedByString:@":"];
    NSLog(@"%@",temp);
    NSInteger mins=[[temp objectAtIndex:1]integerValue];
    //check your interval here
    if (mins<=29) {
        selectedTime=[NSString stringWithFormat:@"%@:%@:%@",[temp objectAtIndex:0],@"00",@"00"];
    }else if (mins>=31 && mins<=59){
        selectedTime=[NSString stringWithFormat:@"%@:%@:%@",[temp objectAtIndex:0],@"30",@"00"];
    }else{
//        selectedTime = [outputFormatter stringFromDate:datePicker.date];
    }
    if (self.delegate && [self.delegate respondsToSelector:@selector(SelectedValue:)]) {
        [self.delegate SelectedValue:selectedTime];
    }
    [self.popupController dismiss];
}

My interval is 30 mins

EDIT Make your class to handle UIControlEventValueChanged event in your picker. Add this line ViewDidLoad method or when your actionsheet shown:

  [picker addTarget:self action:@selector(dateChanged:) 
          forControlEvents:UIControlEventValueChanged];

Now selector would be called when date is changed

UPDATE

- (void) dateChanged:(id)sender{
    // handle date changes and set in textField
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    NSString *strdate = [dateFormatter stringFromDate:self.datePicker.date]; //provide your selected date here
    self.dateTexField.text = strdate;
}

If above method is not called means date is not changed so always set default date in your textField.

Convert date to string object

UPDATE

 NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
 NSString *strdate = [dateFormatter stringFromDate:self.datePicker.date]; //provide your selected date here

Now set value to textField like this:

  self.dateTextField.text = strdate;

I think the easiest way is just to attach a toolbar with a done button to your TextField that has the UIDatePicker as its inputView. Keep track of your current TextField by maintaining a reference to it in TextViewDidBeginEditing. Then in the done button do something like this:

if (_currentTextField == _myTextFieldThatUsesADatePicker) {
    self.myDateProperty = _myDatePicker.date;
}

Just set the dateSelected from your date picker after select button press.... 

NSDate *date = datePicker.date;
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"dd/MM/yyyy"];    
NSString *dateString = [formatter stringFromDate:date];
yourTxtField.text = dateString;
