Question

I have a modalviewcontroller and have two buttons on it: Cancel and Save. There is a UITextField which is editable.
Whenever I click on save button I do save it but the text doesnot get save because when I click on the button to open the modalviewcontroller, the text disappears. Dont know whats wrong with my code.
Here is my code :

- (void)viewWillAppear:(BOOL)animated {

self.cancel = self.navigationItem.leftBarButtonItem;
self.save = self.navigationItem.rightBarButtonItem;

UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc] initWithTitle:@"Cancel" style:UIBarButtonItemStylePlain target:self action:@selector(cancelAction)];
self.navigationItem.leftBarButtonItem = cancelButton;
[cancelButton release];

UIBarButtonItem *saveButton = [[UIBarButtonItem alloc] initWithTitle:@"Save" style:UIBarButtonItemStylePlain target:self action:@selector(saveAction)];
self.navigationItem.rightBarButtonItem = saveButton;
[saveButton release];

[super viewWillAppear:animated];
}

-(IBAction) cancelAction{
[[self parentViewController] dismissModalViewControllerAnimated:YES];   
  }

  -(IBAction) saveAction{
 NSString *text = [textFieldBeingEdited text];

[textFieldBeingEdited setText:text];
[self setDescription:text];


[[self parentViewController] dismissModalViewControllerAnimated:YES];   
   }

I am not sure if I have to use the following code to save the text in textfield :

- (void)textFieldDidEndEditing:(UITextField *)textField
   {
[self dismissModalViewControllerAnimated:YES];
   }

I don’t see in your code anywhere that you are setting the text in the UITextField when the view appears. You can add some code to your viewWillAppear method to set the text when the view appears, such as:

[textField setText:[self description]];

(It looks like you are storing the NSString in the description variable.)

Also, if this is some kind of string that could be considered a User Default, you can store the string there. I’ve used this before and it populates my UITextField nicely.

Code Example:

-(void)viewDidLoad
{
stringValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"string"];
[textField setText:stringValue];
}

-(IBAction)saveAction
{
stringValue = [textField text];
[[NSUserDefaults standardUserDefaults] setObject:stringValue forKey:@"string"];
}
