Question

I’ve a UITableViewController which has Edit/Save and cancel buttons. At present I’m displaying 5 row’s of custom UITableViewCell’s. Custom UITableViewCell contains textfield and label. Let’s say if user enters text in 1st table cell and hits “Save” then I’m losing the entered/modified text. Whereas if user hits return key after entering/modifying text then the entered/modified value is captured via:

- (BOOL)textFieldShouldEndEditing:(UITextField *)textField 
{
.......code exists to capture value here
}

but on the other hand if user hits “Save” button without returning the textfield then I’m losing the entered/modified value. What’s the best way to capture user’s input here:

a) when user returns text field –> which I’m doing already
b) when user hits save button without returning textfield/textview –> ????

thanks in advance,
Rama

Answer 1

You could keep a property that holds the string as it’s being entered using a delegate method. Something like:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    NSMutableString *testString = [NSMutableString stringWithString:self.textField.text];
    [testString replaceCharactersInRange:range withString:string];
    self.stringInProgress = testString;
    return YES;
}

Another option might be to call [tableView endEditing] as the first thing to do on a save but I’m not certain that fires the textFieldShouldEndEditing: notification.
