Can't get values from text fields from UITableView - iphone

Question

I have a UITableView that I used for username/password enter.
But I have problem to get values when I click on button.
This is how I make table:
- (UITableViewCell *)tableView:(UITableView *)table cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *kCellIdentifier = #"Cell";
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:kCellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:kCellIdentifier];
cell.accessoryType = UITableViewCellAccessoryNone;
if ([indexPath section] == 0) {
UITextField *playerTextField = [[UITextField alloc] initWithFrame:CGRectMake(110, 10, 185, 30)];
playerTextField.adjustsFontSizeToFitWidth = YES;
playerTextField.textColor = [UIColor blackColor];
if ([indexPath row] == 0) {
playerTextField.placeholder = #"example#gmail.com";
playerTextField.keyboardType = UIKeyboardTypeEmailAddress;
playerTextField.returnKeyType = UIReturnKeyNext;
}
else {
playerTextField.placeholder = #"Required";
playerTextField.keyboardType = UIKeyboardTypeDefault;
playerTextField.returnKeyType = UIReturnKeyDone;
playerTextField.secureTextEntry = YES;
}
playerTextField.backgroundColor = [UIColor whiteColor];
playerTextField.autocorrectionType = UITextAutocorrectionTypeNo;
playerTextField.autocapitalizationType = UITextAutocapitalizationTypeNone;
playerTextField.textAlignment = NSTextAlignmentLeft;
playerTextField.tag = 0;
playerTextField.clearButtonMode = UITextFieldViewModeNever;
[playerTextField setEnabled: YES];
playerTextField.backgroundColor = [UIColor clearColor];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
[cell addSubview:playerTextField];
}
}
if ([indexPath section] == 0) { // Email & Password Section
if ([indexPath row] == 0) { // Email
cell.textLabel.text = #"Email";
}
else {
cell.textLabel.text = #"Password";
}
}
return cell;
}
And this is what I have tried in button tap:
...
for (UITableViewCell* aCell in [self.tableView visibleCells] ) {
UITextField* aField = (UITextField *)[aCell viewWithTag:0];
NSLog(aField.text);
}
..
This prints me just: Email Password (labels not data that I entered).
How to get entered values here?

Answer 1

All views default their tag to 0. Because of this, [aCell viewWithTag: 0] is returning the first view with tag zero - in this case the cell's textLabel - which is a UILabel that also responds to .text. If you set the tags in your cellForRowAtIndexPath: to something other than zero it should start working for you.

Answer 2

In that case you can give the tag to textfield like playerTextField.tag = 115 and you can get view by tag like UITextField *aField = (UITextField *)[aCell viewWithTag:115]; and display NSLog(#"text:%#",aField.text);
