How to get UITextField values when button is clicked - iphone

Question

I have this view:
and these implementations:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [self.tableLogin dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier] autorelease];
cell.accessoryType = UITableViewCellAccessoryNone;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
if ([indexPath section] == 0) {
UITextField *textfield = [[UITextField alloc] initWithFrame:CGRectMake(110, 10, 165, 30)];
textfield.adjustsFontSizeToFitWidth = YES;
textfield.textColor = [UIColor blackColor];
textfield.backgroundColor = [UIColor whiteColor];
textfield.autocorrectionType = UITextAutocorrectionTypeNo;
textfield.autocapitalizationType = UITextAutocapitalizationTypeNone;
textfield.textAlignment = UITextAlignmentLeft;
textfield.clearButtonMode = UITextFieldViewModeNever;
textfield.delegate = self;
if ([indexPath row] == 0) {
textfield.tag = 0;
textfield.placeholder = #"your username";
textfield.keyboardType = UIKeyboardTypeDefault;
textfield.returnKeyType = UIReturnKeyNext;
}
else {
textfield.tag = 1;
textfield.placeholder = #"required";
textfield.keyboardType = UIKeyboardTypeDefault;
textfield.returnKeyType = UIReturnKeyDone;
textfield.secureTextEntry = YES;
}
[textfield setEnabled:YES];
[cell addSubview:textfield];
[textfield release];
}
}
if ([indexPath section] == 0) {
if ([indexPath row] == 0) {
cell.textLabel.text = #"Email";
}
else {
cell.textLabel.text = #"Password";
}
}
return cell;
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
switch (textField.tag) {
case 0:
self.username = textField.text;
break;
case 1:
self.password = textField.text;
break;
}
return true;
}
When the user click Login button without tap "Done" for close the keyboard it doesn't save the field values. How can I tricky-fix this?

Answer 1

Two options:
Keep a reference to both textfields and pull their text values in the "Done" button's action method.
Alternatively, register for the UITextFieldTextDidChangeNotification and capture input as it happens.

Answer 2

You can use - (void)textFieldDidEndEditing:(UITextField *)textField and save your values there, in addition to hitting the return key.
