How to call actions between classes?!

Question

Hi guys, yeah it's me again :)

I've got a little problem.

I've got a custom cell with a TextField. I want the keyboard to hide when i tap "done"

so normally i do this jus with [sender resignFirstResponder].

In this case that doesn't work because the custom cell is a class itself and has its own .h and .m files.

How is it possible to link something like that in general?

Answer 1

okay, sorry thouht it was clear :)

I've got a UITableViewCell. Within this cell there's a UITextField. If I edit this textfield the keyboard shows up. To hide the keyboard I normally make a function in the obove viewController. It contains only this [sender resignFirstResponder]. In this case that doesn't help.

So the first question is where do i write this action. The second question is: How do i for example set the propertys for a class.(I've got a class like where I define my CLLocationmanager and i want to set the parameter for this in another view controller.

I hope that this is better to understand :)

Sorry for the bad questioning in the first post. Thank you!

Btw I am not able to edit the obove post...

Set your UITextField's delegate to the UIViewController. You can do this in Interface Builder (if you created your UITableViewCell like that), or through code (in your UIViewController).

tableViewCell.textView.delegate = self

Now, in your UIViewController, add this function:

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
  [textField resignFirstResponder];
  return NO;
}

This code hasn't been tested, but it should probably work.
