Question

This question is a bit related to one I posed previously entitled “Recognizing UIButton from a loop“.

In this case, I have generated a bunch of UITextFields with a loop. When the value of one of them is changed, I’m able to recognize which textfield it was.

However, I want to then edit every textfield that was generated. Specifically, I get input from the one textfield that was edited, and I want to recalculate the other textfields based on the input and name of the recognized textfield.

How do I call for every one of the other generated, non-edited textfields to be modified?

Since you are already using tags, this is what viewWithTag is used for:

// Get a reference to the textfield with tag 3
UITextField *textField3 = (UITextField *)[self.view viewWithTag:3];

// Calculate your new value
float result = 4.32; // Calculate the value that you want the textfield with tag 3 to display

// Change the contents
textField3.text = [NSString stringWithFormat:@"%f", result];
