Problem with a call button - doesn't open tel:// URL
I am trying to make a call button that will call 18 which is Fire Dept in France.
So my code is :
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://18"]];
It doesn't work and I get this message in the console :
< warning > Ignoring unsafe request to open URL tel://18
But I saw other application that have the same button fully working !
I am trying this on the device of course.
What am I missing ?
Ok I Found the answer after wasting many hours...
Here is the solution :
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://18?1"]];
The iPhone accepts the interrogation mark but ignores it when initiating the call !
In Safari, if you try this :
It won't work but if you try this :
It will call 18 !
The correct url has no backslashes. That is, it should be tel:18
tel://18?1 works fine on iOS4, but it seems that iOS5 ignores everything after the ? character and refuses to just call 18...
However, tel://18♯1 works on iOS5 (and calls number 18) but not on iOS4, so you have to switch according to the iOS version of the client.
