Failed to call

Question

I want to make a phone call, and for this I use the code below.

- (void)callPhoneNumber:(NSString *)phoneNumber
{
    UIWebView * webView2 = [[UIWebView alloc] init];

    // Remove non-digits from phone number
    phoneNumber = [[phoneNumber componentsSeparatedByCharactersInSet:[[NSCharacterSet decimalDigitCharacterSet] invertedSet]] componentsJoinedByString:@""];

    // Make a call
    NSURL * url = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", phoneNumber]];
    [webView2 loadRequest:[NSURLRequest requestWithURL:url]];
    [self.view addSubview:webView2];
}

Before calling, I will ask the user to select an option using UIActionSheet. When the user selects a parameter, based on which I place a call.

The problem is that the above code works fine if I don't show UIActionSheetand place the call directly. It asks for a warning requesting user confirmation for making a call. But after displaying UIActionSheet, if I call the method above, it does not display confirmation confirmation.

NSString *phoneNumberURL = [NSString  stringWithFormat:@"telprompt:%@", phoneNumber];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumberURL]];
