从iPhone OS 3.0呼叫的代码不起作用？

Question

NSString *StrPhoneNo = @"(21) 2197-78797";

[[UIApplication sharedApplication] openURL:
      [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", StrPhoneNo]];

This is not working?

Answer 1

The phone number doesn't look correct to me. I don't know where you're located, but I guess you need a 0 or 1 in front of the phone number. Or if it's an international number, add a "+" in front of the country code.

Answer 2

In my code I'm calling "+353876543210" and it's working fine. So I guess the phone number is in the wrong format.
