Sending data from a Text Field to a Mutable Array

Question

I have a textfield that I am trying to have the data sent to a Mutable Array when the user presses done. The only way this works is when I do textFieldArray = [[NSMutableArray alloc]initWithObjects:self.textField.text, nil]; but then it rewrites the mutable array when the user taps adds another object. Here is my code:

- (IBAction)doneButton:(id)sender {

[self resignFirstResponder];

[textFieldArray addObject:self.textField.text];

NSLog(@"array: %@", textFieldArray);
}

This may be flagged as a duplicate question but I cannot find anything that solves my problem, Thanks for helping.

What's wrong with the code you posted? The code appears to be correct. — rmaddy

@rmaddy it doesn't add the object to the array. When I log it it says (null) — user3186310

@rmaddy Thanks, just tried that but it just overwrites whatever is in the array, not add to the array. — user3186310

Where are you initializing the array? It should be done once in the proper init method. — rmaddy

Just add this to viewDidLoad: method and it should work fine:

textFieldArray = [[NSMutableArray alloc]init];

You need to allocate and initialise this array,but not every time you adding new object in Array.

I'd put this in the proper init... method since it really has nothing to do with views.

@Greg My bad it does work, I had a typo in my code. Thanks for the help.

Have you added this line I posted to viewDidLoad and it still override the data?

Try this:

- (IBAction)doneButton:(id)sender {
     if(!textFieldArray)
     {
         textFieldArray = [[NSMutableArray alloc]initWithObjects:self.textField.text, nil];
     }
     else
     {
        [textFieldArray addObject:self.textField.text];
     }
}
