iOS6: Changed behavior when using tel://-url to dial phone number

I am seeing an undocumented changed behaviour, when using the tel:-URL-Scheme to dial a phone number.

Example

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://232322"]];

In iOS4 and iOS5 after the called ended, the user was left in the phone app. In iOS 6 the app, that made the call, is now relaunched. Interestingly making a facetime-Call using the facetime:// URL does not relaunch the app. Not very consistent:) Does anyone know how to control that behaviour, so it behaves like under iOS4/iOS5?

Solution

  • You can't, the implementation is totally up to the app that response the URL scheme. In the case of the tel: scheme it's the dialer.

    Since Apple does have not released any scheme parameter for tel: there is no way to control the behavior of the dialer.
