Question

From coded detailView of my app which has a grouped table view. I want app to dial selected phone number or send text or send email if clicked on email and take to google maps if address is selected.
this is my didSelectRowAtIndexPath.. and its not working. i don’t know how to get info of selected cell. Please help.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

    Directory *text = (Directory *)[tableView cellForRowAtIndexPath:indexPath];

    //check content of text.
    NSLog(@"Phone Number Selected is %@", text);

    //NSString *dialHome = [dispHomephone stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:[phone]"]]
}

And here is my cellForRowAtIndexPath if it helps.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    int cellPhoneLen = [dispCellphone length];
    int workPhoneLen = [dispWorkphone length];
    int homePhoneLen = [dispHomephone length];
    int emailLen = [dispEMail length];

    NSString *address = [NSString stringWithFormat:@"%@\n"@"%@ %@ %@\n"@"%@", dispAddress, dispCity, dispState, dispZip, dispCountry];
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:CellIdentifier] autorelease];
    }

    cell.selectionStyle = UITableViewCellSelectionStyleBlue;

    // Configure the cell...
    switch (indexPath.section) 
    {
        case 1:
        {
            if (homePhoneLen != 0)
            {
                switch (indexPath.row)
                {
                    case 0:
                    {
                        if (homePhoneLen != 0)
                        {
                            cell.textLabel.text = NSLocalizedString(@"home :", @"homephone label");
                            cell.detailTextLabel.text = dispHomephone;
                        } break;
                    case 1:
                        if (workPhoneLen != 0)
                        {
                            cell.textLabel.text = NSLocalizedString(@"work :", @"workphone label");
                            cell.detailTextLabel.text = dispWorkphone;
                        } break;
                    case 2:
                        if (cellPhoneLen != 0)
                        {
                            cell.textLabel.text = NSLocalizedString(@"mobile :", @"cellphone label");
                            cell.detailTextLabel.text = dispCellphone;
                        }
                    }
                }
            }

• First off, what is Directory? Looking at your first code snippet, it looks like Directory is a subclass of UITableViewCell, but then your second snippet indicates that you are not using a UITableViewCell subclass.

  Change this line:

  Directory *text = (Directory *)[tableView cellForRowAtIndexPath:indexPath];

  To this:

  UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

  Then you can get the values of the UITableViewCell like this:

  NSString *myString = cell.detailTextLabel.text

I’ll leave it for you to determine what type of information is stored in the cell because you know better how your app works.

• To make a call do this:

  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel://%@",myString]]]

• To send a text do this:

  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"sms://%@",myString]]]

• To open maps do this:

  myString = [addressText stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];
NSString* urlString = [NSString stringWithFormat:@"http://maps.google.com/maps?q=%@", myString];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlText]];

• To send an email do this:

  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"mailto://%@",myString]]]
