Make Phone Call from TableView cell

[james4026]

I've seen

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://"]];

where you are suppose to enter the number to be called. How do you get it to call a number that appears as detailTextLabel in a cell?? The detailTextLabel has been set as an NSMutableArray as has the actual TextLabel. This appears in a tableview as well.

I have only been using xcode for about 2 weeks so please be 'gentle' with me, haha.

Thanks!!

Use the table delegate's tableView:didSelectRowAtIndexPath: method to find which cell was tapped and dial the associated number.

Like this?

- (void)tableViewUITableView *)tableView didSelectRowAtIndexPathNSIndexPath *)indexPath {

[[UIApplication sharedApplication openURL: [NSURL URLWithString:@"tel://"];


I assume that something needs to go with "tel://" so that it knows where to get the number from?? The numbers are in an NSarray called cabNumbers if that helps.

You would get it from the data source where you populate the table from (most likely your array), using the indexPath parameter to get the one that was tapped.

Assuming your table view has a row for every entrain your cabNumbers array, you could use code like this:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{
  NSString* phone = [cabNumbers objectAtIndex: indexPath.row];
  NSString* urlString = [NSString stringWithFormat: @"tel://%@", phone];
  [[UIApplication sharedApplication openURL: [NSURL URLWithString: urlString];
}

The trick is the "stringWithFormat" method. It takes a format string as a parameter, and lets you combine strings with other strings, convert numbers to strings, and do various other types of format conversions. The "%@" in the format string above means "replace %@ with the contents of an object." When the object is a string, it replaces the "%@" with the contents of the string.

Do a search for "String Format Specifiers" in the XCode help system, and look for the section in the String Programming Guide titled "String Format Specifiers" for more information on using string formatting.
