Xcode show UIAlertView after UITableRowSelection? - ios

Question

this is my first question, sorry if something is wrong
Well I'm trying to create a view in which i can select a friend from a table view and then it should say the number and the mail on a UIAlertView but I dont know how to do this
the friend list is obtained from an xml file on my site, and then is parsed an showed on a table with a custom cell design
this is the code that creates each cell
- (UITableViewCell *)tableView:(UITableView *)myTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = (UITableViewCell *)[self.messageList dequeueReusableCellWithIdentifier:#"ContactListItem"];
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"ContactListItem" owner:self options:nil];
cell = (UITableViewCell *)[nib objectAtIndex:0];
}
NSDictionary *itemAtIndex = (NSDictionary *)[messages objectAtIndex:indexPath.row];
UILabel *userLabel = (UILabel *)[cell viewWithTag:2];
userLabel.text = [itemAtIndex objectForKey:#"user"];
return cell;
}
thanks
Santiago

Answer 1

You have to implement the didSelectRowAtIndexPath: method.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSDictionary *itemAtIndex = (NSDictionary *)[messages objectAtIndex:indexPath.row];
NSString *name = [itemAtIndex objectForKey:#"user"];
NSString *email = [itemAtIndex objectForKey:#"email"];
NSString *phone = [itemAtIndex objectForKey:#"phone"];
NSString *messageStr = [NSString stringWithFormat:#"Email : %#\nPhone : %#", email, phone];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:name message:messageStr delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}

-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath is the method you would need to implement. This is assuming the view you are presenting the table view in is the delegate for the table view.
-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//Alert view logic happens here getting all the cell information
}
