Hope that helps Either save the text/string using NSUserDefaults or you can use SQLite to save/update/insert/retrieve the data.And when displaying it in textfield just retrieve it from sqlite…

Saving UITextField Input

Saving UITextField Input

should help you out Ive had a look at many other questions regarding this (I know there are alot!), but none seem to satisfy my query. Basically I have a view controller which includes two UITextFields. The app is designed so that this page loads, the user inputs numbers, and then taps the background to get rid of the keyboard, and the values save. I then want this to be pre loaded in the text field every time the user navigates back to the page. I presume I will have to create another IBAction called saveData or something, but is there anyway to automatically save it when the background is tapped? Also to save the data I was thinking of using NSUserDefaults, are there any other methods to save data? Any help is appreciated, Michael I use the following code for the editing and background tap part of my application: , NSUserDefaults will work nicely for this:
code :
-(IBAction) backgroundTap:(id) sender {

    NSString *inputOne = textInputOne.text;
    NSString *inputTwo = textInputTwo.text;

    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    [userDefaults setObject:inputOne forKey:@"InputOne"];
    [userDefaults setObject:inputTwo forKey:@"InputTwo"];

    [textInputOne resignFirstResponder];
    [textInputTwo resignFirstResponder];
    [sender resignFirstResponder];
}
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];   
textInputOne.text = [userDefaults objectForKey:@"InputOne"];
textInputTwo.text = [userDefaults objectForKey:@"InputTwo"];

this will help Couldn't you link both events to the same action? Maybe you could make a BOOL in your header file called needsSaving. Set it to NO every time editing begins, then YES every time the data is saved successfully. Then only execute the body of your saving methods if needsSaving is NO, that will avoid unnecessary saving. I think doing this would simplify this function of your app. i.e.
code :
- (IBAction)col2_singleValueEditDidBegin:(id)sender {
    needsSaving = YES;
}

- (int)saveDataToServer
{
    [self.tableView resignFirstResponder];

    if (!dirtyFlag || !needsSaving) {
        return 0;
    }

    NSString *errors = [DataSource updatePatientWorkflowClinicalChecklistForAppointment:[[[DrChronoDataSource getCurrentAppointment] valueForKey:@"appointment_id"] intValue] clinicalInfo:self.clinicalChecklist checklistId:[self.clinicalChecklistId intValue] patientWorkflowServerId:patientWorkflowServerId];

    if ((NULL == errors) || ![errors isEqualToString: @""]) {
        //Show error messages.
        if (NULL == errors) {
            errors = @"Failed to save data to server.  Please retry.";
        }
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Status" message:errors delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [alert show];
        [alert release];
        return -1;
    } else {
        needsSaving = NO;
        [self dismissModalViewControllerAnimated:FALSE];
    }

    self.dirtyFlag = 0;
    return 0;
}

Hope this helps You are never setting the Name value, it should be done in alertView:clickedButtonAtIndex:
I would also suggest doing away with the @"1", and either checking for nil (as @Roman suggests) or storing a BOOL in another defaults key.
code :
...
utextfield.tag = 9876; // some value likely not in use by the internals



- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
  if (buttonIndex == alertView.cancelButtonIndex) {
    [[NSUserDefaults standardUserDefaults] removeObjectForKey:@"Name"];
  } else if (buttonIndex == alertView.firstOtherButtonIndex) {
    UITextField *utextfield = (UITextField *)[alertView viewWithTag:9876];
    [[NSUserDefaults standardUserDefaults] setValue:utextfield.text forKey:@"Name"];
  }
  [[NSUserDefaults standardUserDefaults] synchronize];
}

it fixes the issue Instead of adding the strings in the textFieldDidEndEditing method, add them on the done button's click method.
Here are some steps you could try in the done button's method:

Initialization of the variable 'secondscountdown' was never used; consider replacing with assignment to '_' or removing it.
code :
  let secondsCountDown = secondsCountField.text
