TableViewCell with touchable's labels - ios

Question

I'm trying to create a tableview that the cells contains name, telephone and mail. If the user touches the telephone, the app calls to the phone (click to call). If the user touches the mail, I need to open the mail app with a new email to the "touched address".
First, I'm trying to develop the touchable label that contains an email, but I'm receiving the error "selector sent to instance".
I need to identify the tapgesture, and then, identify if it's an email or telephone, get the text and calls or open mail app.
Current code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
...
cell.lblEmail.userInteractionEnabled = YES;
UITapGestureRecognizer *tapGesture =
[[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(labelTap)];
[cell.lblEmail addGestureRecognizer:tapGesture];
return cell;
}
- (void)labelTap:(UIGestureRecognizer *)sender {
UILabel *labelSender = (UILabel*) sender;
NSLog(#"%text: %#", labelSender.text);
}

Answer 1

Change this line:
[[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(labelTap)];
to
[[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(labelTap:)];
This is required because labelTap as a selector is distinct from labelTap:. The former is a selector with no parameters (which doesn't exist, hence the exception), and the latter is the one with 1 parameter, which you have indeed defined.

Vinod, Claus were correct. I changed for UIButton and worked perfectly.
I'm identifying witch mail was selected, with this code: Detecting which UIButton was pressed in a UITableView
