How to save and load UITextField using NSUserDefaults?

Question

Possible Duplicate:
How would I save and load a UITextField?

I have tried EVERYTHING and unfortunately nothing works for me. I have probably tested about 10 ways of saving and loading the UITextFields but they don't work. I have six UITextFields and want to save them when a button is pressed and load when viewDidLoad is called.

Please can I have some help as I've got to publish the app within the next day or two and I still haven't managed to do this...

Thanks,

James

If you could post some code on what you are trying it'd be very helpful — Suhail Patel, Sep 06 '11 at 10:10
There's so many different types I've tried but I deleted the code once it hadn't worked... I literally tried everything that's listed on here and I followed several tutorials... — pixelbitlabs, Sep 06 '11 at 10:17

NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];

NSString* textField1Text = textField1.text;
[defaults setObject:textField1Text forKey:@"textField1Text"];

NSString* textField2Text = textField2.text;
[defaults setObject:textField2Text forKey:@"textField2Text"];

NSString* textField3Text = textField3.text;
[defaults setObject:textField3Text forKey:@"textField3Text"];

NSString* textField4Text = textField4.text;
[defaults setObject:textField4Text forKey:@"textField4Text"];

NSString* textField5Text = textField5.text;
[defaults setObject:textField5Text forKey:@"textField5Text"];

NSString* textField6Text = textField6.text;
[defaults setObject:textField6Text forKey:@"textField6Text"];

[defaults synchronize];

NSString* temp = [defaults objectForKey:@"textField1Text"];
NSString* temp = [defaults objectForKey:@"textField2Text"];
NSString* temp = [defaults objectForKey:@"textField3Text"];
NSString* temp = [defaults objectForKey:@"textField4Text"];
NSString* temp = [defaults objectForKey:@"textField5Text"];
NSString* temp = [defaults objectForKey:@"textField6Text"];

NSLog(@"%@,%@,%@,%@,%@,%@",temp1,temp2,temp3,temp4,temp5,temp6);

NEW EDIT

  - (IBAction) saveBtnPresssed : (id) sender
  {

        NSUserDefaults *defaults=[NSUserDefaults standardUserDefaults];

        NSString* textField1Text = textField1.text;

        [defaults setObject:textField1Text forKey:@"textField1Text"];

        NSString* temp = [defaults objectForKey:@"textField1Text"];

        NSLog(@"%@",temp);

  }

Can we continue talking on chat please? – pixelbitlabs Sep 06 '11 at 11:17
All works now, thanks for your help! I simply put the viewDidLoad text under ApplicationDidFinishLaunchingWithOptions section :) – pixelbitlabs Sep 06 '11 at 11:21

This link may be helpful to you.

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

// saving an NSString

[prefs setObject:@"your textField text" forKey:@"keyToLookupString"];

I've just tried that and it didn't work for me. Here's my code; Code for button to save: http://pastie.org/2490681 Code for viewDidLoad: http://pastie.org/2490687 – pixelbitlabs Sep 06 '11 at 10:17
I've added an answer below about synchronising after looking at your code. Give it a try :) – Suhail Patel Sep 06 '11 at 10:21
Didn't work for me unfortunately :( – pixelbitlabs Sep 06 '11 at 10:30

After you set your Objects you need to call synchronise to have it saved and committed into your User Defaults like so (Using the example you provided above in a comment):

- (IBAction)doSaveAllNotes{

    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
    [prefs setObject:Assignment1.text forKey:@"Assignment1Text"];
    [prefs synchronize]; // This is to save it and is pretty important!

    NSLog(@"Saved All Notes");
}

Still not working, even with "[prefs synchronize];" added... :S – pixelbitlabs Sep 06 '11 at 10:26
You need to give us more info, is the `Assignment1.text` proper text? You sure it isn't nil? Is the `doSaveAllNotes` method being called? – Suhail Patel Sep 06 '11 at 10:35
Assignment1.text doesn't have any text when loaded, it has a placeholder, is this an issue? I did type into it then press save but still didn't work :( – pixelbitlabs Sep 06 '11 at 10:46
And yes, that method is being called. – pixelbitlabs Sep 06 '11 at 10:46
