How to change text in UITextView and UITextField

I need to edit my UITextView and when I make these changes I need them to reflect that in my UITextFields. Currently i can use the code below to move whatever text i write into the first UITextField is there a simple way to move each line to a separate UITextField?

Like the image, except the 1, 2 and 3 going to a different UITextField.

-(IBAction)print:(id)sender {

NSString *texto = [[NSString alloc] initWithFormat:@"%@ %@",[myTextField text],[myTextView text]];
[myTextField setText:texto];
[myTextView setText:@""];
[myTextView resignFirstResponder];

}

Like this

Really, I need to figure this out. Any help will be appreciated.

Have your view controller conform to the UITextViewDelegate protocol.

Next, set the delegate property of your text view to your view controller.

Then, implement - (void)textViewDidChange:(UITextView *)textView, along these lines:

- (void)textViewDidChange:(UITextView *)textView
{
    // Set the text for your text fields.
    //
    // (I'm assuming your code for determining the text to put in the
    // text fields works as you intend, so I'm just copying it here.)

    NSLayoutManager *layoutManager = [textView layoutManager];
    unsigned numberOfLines, index, numberOfGlyphs = [layoutManager numberOfGlyphs];
    NSRange lineRange;

    for (numberOfLines = 0, index = 0; index < numberOfGlyphs; numberOfLines++)
    {
        (void) [layoutManager lineFragmentRectForGlyphAtIndex:index
                                               effectiveRange:&lineRange];

        index = NSMaxRange(lineRange);
        NSString *lineText = [textView.text substringWithRange:lineRange];
        [yourArray addObject:lineText];
    }

    textField1.text=yourArray[0];
    textField2.text=yourArray[1];
    textField3.text=yourArray[2];
    textField4.text=yourArray[3];
    textField5.text=yourArray[4];
    textField6.text=yourArray[5];
    textField7.text=yourArray[6]; 
}
