Create textfields based on user input

Question

I want to create textfields based on user input. Let's say 5 textfield are needed

for (int x = 0; x < self.howMany; x++) 
{
    NSLog(@"%i", x_position);
    self.textFieldRounded = [[UITextField alloc] initWithFrame:CGRectMake(10, x_position, 300, 25)];
    self.textFieldRounded.borderStyle = UITextBorderStyleRoundedRect;
    self.textFieldRounded.textColor = [UIColor blackColor]; //text color
    self.textFieldRounded.font = [UIFont systemFontOfSize:17.0];  //font size

    [self.view addSubview:self.textFieldRounded];
    x_position += 30;
}

So far, so good. That code create five textfields. The problem is that these textfields are not "unique". Each of these textfield can contain different information. What to do so that I can gather information of each of these fields ?

Answer 1

Add a tag to them.

int i = 1;
for (int x = 0; x < self.howMany; x++) 
{
    NSLog(@"%i", x_position);
    self.textFieldRounded = [[UITextField alloc] initWithFrame:CGRectMake(10, x_position, 300, 25)];
 textFieldRounded.tag = i++;
 ...

And then, when you need to find textfield 3 for example, do:

UITextField *textField = (UITextField *)[self.view viewWithTag:3];

Answer 2

You could set a tag for each text field.

self.textFieldRounded.tag = x;

Then you can use the tag to identify your text fields. You can iterate through self.view to find all subviews (text fields) using this technique.
