Which UITextField delegate method will be called without resing keyboard?

Question

I am in situation where user enters data into UITextField in without resign of keyboard he presses Next button go to next page.

That textfield is in custom cell with UITextView. Now I want to capture everything in every textfield & UITextView of that UITableView when user enters into it because at time of Next button click I need to save the data.

Till Now I have implemented below methods but none of these getting called when user enters data into TextField and directly press Next button without returning keyboard

- (void)textFieldDidEndEditing:(UITextField *)textField
{

    NSString *strTitle = [textField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
    textField.text = strTitle;


}


- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{   

    return YES;
}

- (BOOL)textFieldShouldEndEditing:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}

What could be the best wat to save from that TextFields before Next?

Answer 1

textFieldDidEndEditing in not always called when you lose the focus. see the post https://stackoverflow.com/a/1229914/641062. It explains a bit about more about the endEditing method's behaviour.

So must save your data in this method. This will called for every character you type.

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{   

    return YES;
}
