How to get other control value from UITableViewCell? - iphone

Question

I have one doubt that how to get other control's value when we select a row or tap on button while having custom tableViewCell.
Suppose I have a TableView Cell with a TextField, a Slider and button. Button has action using:
btn.tag = indexPath.row;
[btn addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
Now I can get button on its action method. I need to get textField's value and slider's value on button tap.
The one option is I create a array and store values for these two control in that array and manage this. But I don't think this is correct way to manage it.
Please navigate me to the currect way to get value of UITableViewCell's subview's value.
Thanks

Answer 1

While creating your textfield and slider, give them a constant tag and then add to cell's contentView
textfield.tag= TEXTFIELDTAG; //TEXTFIELDTAG = 100 or any other constant
[cell.contentView addSubview:textfield];
and then in your buttonTapped: method
-(void)buttonTapped:(id)sender
{
int row = ((UIButton*)sender).tag;
NSIndexPath* indexpath = [NSIndexPath indexPathForRow:row inSection:0]; // in case this row in in your first section
UITableViewCell* cell = [table cellForRowAtIndexPath:indexPath];
UITextField* textfield = [cell.contentView viewWithTag:TEXTFIELDTAG];
}

Whenever you create subviews (button , text field etc. ) for your UITableViewCell don't forget to tagged them.
myTextField.tag = 0;
myTextLabel.tag = 1;
[cell addSubview:myTextField];
[cell addSubview:myTextLabel];
Once you tagged, you could access them using below method.
- (UIView *)viewWithTag:(NSInteger)tag
When you select,you could get the subviews of your UITableViewCell's by using ViewWithTag function of UIView.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableview cellForRowAtIndexPath:indexPath];
UITextField* myTextField = [cell viewWithTag:0];
UILabel* myTextLabel = [cell viewWithTag:1];
}
