URL schemes in table cells

[alexanderMobile]

Hi,

The documents mention you can use different URL schemes like mailto and tel to open up mail or make a call. How would you integrate this so when a table's cell is clicked, it performs the equivalent of if a mailto hyperlink was clicked?

You need to implement a UITableViewDelegate method in e.g. your UIViewController subclass:

- (void)tableViewUITableView *)tableView selectionDidChangeToIndexPathNSIndexPath *)newIndexPath fromIndexPathNSIndexPath *)oldIndexPath

Assuming your table cell references a URL you can simply launch that URL using:

UIApplication* theApp = [UIApplication sharedApplication]; //get application singleton
[theApp openURL: url];

Thanks, that's what I was after.

However, when trying it out, I get errors based on the URL:

UIApplication* theApp = [UIApplication sharedApplication];
[theApp openURL:[NSURL URLWithString:@"mailto:test@example.com"]];

This returns the error
"Unsupported URL
The URL wasn't loaded mailto:test@example.com"

UIApplication* theApp = [UIApplication sharedApplication];
[theApp openURL:[NSURL URLWithString:@"http://www.google.com"]];

Here, my application minimizes (zooms out), screen goes black, then the simulator shuts down.

Is this normal behavior in the Simulator?

Yes, that's normal on the simulator. What's happening is that your application is launching an external application using that URL: this causes your application to exit, and the debugger closes. On the simulator there is no handler for the "mailto:" protocol-- thus you get the other error.

Give it a try on an actual device?
