UITableView上的reloadData后未选择文本字段

Question

In my UITableView I have rows which contain 4 textfields each. After user ends editing couple of things in UITableView datasource are being recalculated, so I need to reload UITableView after edition of textfield. But because tableview is being reloaded, when user touches another textfield to edit while editing the first one, second textfield doesn't get selected. He has to touch it again before it can be edited.

Is there a way to avoid this behaviour? Unfortunately I do need to use reloadData instead of reloadSections or reloadRows methods. Any help will be appreciated, thanks!

Answer 1

Reloading a table view will resign the first responder of the text field or even text view. You could try this trick if you have multiple changes that need to be made.

[[self tableView] beginUpdates]
[[self tableView] endUpdates]

Answer 2

Try assigning a gestureRecognizer to each field or same one to all fields. Once you capture the touch in required field, capture the tag and make that field the firstResponder .

Answer 3

Summing up all the help I received and my own ideas I've gone with the following:

-Delay reload for 0.01 sec so textFieldDidBeginEditing gets called

-Then save textfield's tag and cell's index path to variables in textFieldDidBeginEditing

-Call reloadData on tableview

-Call becomeFirstResponder on textfield saved with variables

This however caused keyboard hiding for a brief moment as it didn't have any responder during reloading. To resolve that I created a fake textfield in tableview's superview and assigned him as a responder up to a moment when tableview was reloaded to assign back to the textfield that was selected by a user.

Certainly not the cleanest solution, but it works.
