Get text from text field on Table cell - ios

Question

I have a custom cell with a UITextField . Where I should set the delegate, in the custom cell class or in the view's class ?
I was trying to do this in both, but no results. I set the delegate from storyboard.
Here is what I did:
-(void)textViewShouldReturn:(UITextField *)textField
{
if ([textField.text isEqualToString:#""]){
return;
}
UIAlertView *helloEarthInputAlert = [[UIAlertView alloc]
initWithTitle:#"Name!" message:[NSString stringWithFormat:#"Message: %#", textField.text]
delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[helloEarthInputAlert show];
}
But this part is working if i put this cell.noteTextField.delegate=self :
-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
self.tableView.frame=CGRectMake(self.tableView.frame.origin.x, self.tableView.frame.origin.y-30, self.tableView.frame.size.width, self.tableView.frame.size.height);
return YES;
}

Answer 1

Add the delegate in the custom cell's class. But do not forget to implement the protocols
// MyCell.h
#interface MyCell : UITableViewCell <UITextFieldDelegate>
// ...
// MyCell.m
-(void)autoconfigureCell // a method I added to configure cell, but also can do in "-(void)layoutSubviews"
{
// ...
myTextField.delegate = self;
// ...
}
-(BOOL)textFieldShouldReturn:(UITextField *)textField // <-- BOOL
{
// do stuff
return YES;
}

You should set the delegate in your ViewController, it has to implement UITextFieldDelegate and to know what textfield is calling the delegate methods, you can do something like this:
-(void)textViewShouldReturn:(UITextField *)textField
{
CGPoint textFieldPosition = [textField convertPoint:CGPointZero toView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:textFieldPosition];
...
}
