Swift-原型单元从TextField获得价值

Question

I have a tableView with 2 prototype Cells.

The first Prototype Cell has a TextField and Button on the right. Let's say it "Cell1"

The second Prototype Cell has only a label. Let's say it "Cell2"

I just want to type something in the first cell and then by taping the Button to :

1) Create a new Cell2 Prototype Cell Row

2) That new Cell2 Prototype Cell Row must have a Label with the value i entered on the Cell1 TextField.

So with that way i could have a list of Cell2 Rows with different values of TextField.

I know how to achieve the first (the new Row created) but not the second.

When the segue starts, i have only the Cell1 Prototype like this photo :

And when i tap the + Button, i have a new Row of "Cell2" Prototype. This kind of Cell must have the label of the Textfield everytime.

How can i take the value of TextField everytime and pass it to new created Cell2 Row Label?

Answer 1

In all probability your difficulty is merely that your data model is a little too simple-minded. Keep in mind that all the work must be done by your cellForRowAtIndexPath: implementation consulting the data model. Thus the data model must know two things for each row:

1. Is this a prototype 1 row or a prototype 2 row?

2. What is the text field (if this is a prototype 1 row) or label (if this is a prototype 2 row) value for this row?

Given a data structure that carries that information, it is clear enough how to proceed:

• As the user types in a text field, the text field delegate should enter the text field's text into the model at that row.

• When the user hits the Plus button, we figure out what row this is and insert into the data model, immediately after the current row, a new entry marked as a prototype 2 row with the same text value as the current row. We then insert the row into the table as well, so that our cellForRowAtIndexPath: is called for the new row.

Given those simple instructions, it's quite easy to build a working example of the sort of thing you're trying to do:
