The setup: The table has 1 custom cell. This cell has 1 text box. In each text box a number is entered. The tableView has 5 rows (of this cell). If I change one number in any of the cells, then all the cells need to be updated, I simply call tableView.reloadData(). The change in the text box is handled with the editingDidEnd event.
The problem: I click any of the textFields and change the number. Then, I click another textField to change its value. first editingDidEnd is called, all the values are re-calculated, and tableView.reloadData is called. Now, the click to the second textField is missed because the table is reloaded.
I am not able to update the cells directly because they are custom cells and the value is changed within that class. I cannot update ALL the cells from custom cell class.
A difficult question to explain in writing especially for a non native English speaker. If you understand the question, any pointers will be appreciated :).
Using Xcode 7.1 and Swift. Thank you.
When you call reloadData, all the cells are removed from the tableview and re-added. Since it is removed, it is no longer in the responder chain meaning its text field can't be the firstResponder (selected).
There are two options that could work.
Keep track of the row that is selected, call reloadData then call becomeFirstResponder on the text field for the correct row.
Not call reload data and just update the values in the text fields. This option more depends on the striation of your app.
